What is an NDMP Server? Understanding Network Data Management Protocol in Depth

I remember a time, not too long ago, when backing up our company’s critical data felt like wrestling a greased pig. It was cumbersome, slow, and honestly, a little terrifying. We’d spend hours, sometimes days, trying to get our tape drives to cooperate, praying that the backups were actually usable if, heaven forbid, we ever needed them. Then, we started hearing about this thing called NDMP, and the phrase “NDMP server” kept popping up in IT discussions. It sounded like a magic bullet, but what exactly *is* an NDMP server, and could it truly alleviate our data protection headaches? This article aims to demystify the Network Data Management Protocol (NDMP) and explain the crucial role an NDMP server plays in modern data management and backup strategies.

The Core Concept: What is an NDMP Server?

At its heart, an NDMP server is a specialized piece of software or a hardware appliance that implements the Network Data Management Protocol (NDMP). This protocol is designed to facilitate efficient and robust data backup and restore operations across a network, particularly for Network Attached Storage (NAS) devices. Instead of relying on client-based agents that consume valuable NAS resources, NDMP allows backup software (the NDMP client) to communicate directly with the NAS filer itself, enabling the NAS to manage its own backups. This direct interaction is what makes NDMP so powerful, especially in enterprise environments with significant NAS storage.

Think of it this way: without NDMP, a typical backup might involve the backup server pulling data from the NAS file by file, over the network. This can be incredibly inefficient, as it uses the NAS’s CPU and network bandwidth for the data transfer, and the backup server also has to manage the whole process. With NDMP, the backup server simply tells the NDMP server (the NAS filer) to perform a backup. The NAS filer then directly transfers the data to the backup destination (often a tape library or another storage device) using its own optimized internal processes, freeing up the backup server and minimizing the impact on the NAS itself.

Why NDMP? The Evolution of Network Data Management

The need for NDMP arose from the growing adoption of NAS devices. As businesses increasingly stored their data on centralized NAS filers, traditional backup methods became a bottleneck. Early NAS devices had limited processing power, and running backup agents directly on them could severely degrade performance, impacting user access to files. Furthermore, managing backups for numerous NAS devices using individual client agents became a logistical nightmare. NDMP was developed to address these specific challenges, offering a standardized, efficient, and scalable solution for NAS data protection.

Before NDMP, data protection for NAS environments often involved:

Client-based backups: Installing backup agents on each NAS filer. This could strain NAS resources, leading to performance issues.
Mounting NAS shares on backup servers: Treating NAS shares like any other network drive and backing them up from a dedicated backup server. This often required the backup server to have sufficient capacity to hold the data temporarily and could be slow.
Proprietary solutions: Each NAS vendor might have had its own unique, often inefficient, method for handling backups.

NDMP offered a vendor-neutral standard that allowed backup software from different vendors to communicate with various NAS devices. This interoperability was a game-changer for IT departments trying to consolidate their data protection strategies and reduce vendor lock-in.

How Does NDMP Work? The Protocol in Action

Understanding the mechanics of NDMP reveals its elegance. The protocol defines a set of commands and data structures that allow a backup application (the client) to control and manage backup and restore operations on a NAS device (the NDMP server). The communication typically occurs over TCP/IP. When a backup job is initiated, the NDMP client connects to the NDMP server on the NAS filer.

The key steps involved in an NDMP backup operation are generally as follows:

Connection Establishment: The NDMP client initiates a connection to the NDMP server on the NAS device, usually on port 10000.
Authentication: The client and server authenticate each other to ensure secure communication.
Command Exchange: The client sends commands to the NDMP server, specifying the data to be backed up, the destination, and other parameters. These commands include:
- CONNECT_SERVER: To establish the initial connection.
- AUTH_CONNECT: For authentication.
- TAPE_OPEN: To open a connection to the backup target (e.g., a tape drive).
- ENVIRONMENT_FILE: To set backup parameters like data format and file history.
- BACKGROUND_FILE_DB_ADD: To instruct the NDMP server to initiate a backup of a specific file or directory.
- BACKUP_FILES: To actually start the data transfer.
- TAPE_CLOSE: To close the connection to the backup target.
- DISCONNECT: To terminate the session.
Data Transfer: The NAS device (NDMP server) directly reads the data from its file system and sends it over the network to the backup destination. This is often referred to as a “three-way handshake” or “direct data path” where the NAS talks directly to the backup device.
Data Verification and Logging: The NDMP server manages the backup process, handles file system metadata, and can even perform basic verification checks before sending the data. It logs the backup operation.
Restore Operations: The process is similar for restores. The NDMP client instructs the NDMP server to retrieve data from the backup destination and write it back to the NAS file system.

A crucial aspect of NDMP is its ability to support different data paths:

Local Data Path: The NAS device directly writes data to a locally attached tape drive. This is the most efficient method, as data doesn’t traverse the network twice.
Remote Data Path: The NAS device sends data over the network to a remote NDMP-aware backup device (like a dedicated backup server with an NDMP interface or another NAS). While still more efficient than client-agent backups, it involves more network traffic.

The choice of data path often depends on the infrastructure and the specific NDMP implementation by the NAS vendor and the backup software vendor.

Key Components of an NDMP Setup

To fully grasp what an NDMP server is, it’s helpful to understand the surrounding components:

NDMP Server (NAS Filer): This is the NAS device itself, running NDMP-compliant software. It initiates and manages the backup and restore operations. Think of it as the “brains” of the backup operation for its own data.
NDMP Client (Backup Software): This is the backup application running on a separate server. It acts as the conductor, telling the NDMP server what to do, when to do it, and where to send the data. Popular backup solutions like Veritas NetBackup, Commvault, IBM Spectrum Protect, and NetWorker all support NDMP.
NDMP-Aware Backup Device: This could be a tape library, a disk-based backup appliance, or even another NAS that can receive data directly from the NDMP server.
Network Infrastructure: Reliable network connectivity (Ethernet, Fibre Channel) is essential for NDMP communication and data transfer.

The interplay between these components is what makes NDMP a powerful solution. The NDMP server on the NAS is responsible for understanding its own file system structure and efficiently reading the data. The NDMP client orchestrates the process, integrating NAS backups into the broader enterprise backup and recovery strategy.

The Role of an NDMP Server in Data Protection

The primary role of an NDMP server is to enable efficient, scalable, and reliable data protection for NAS environments. By offloading the backup process from the backup server to the NAS device itself, NDMP significantly enhances performance and reduces the burden on network resources. This is particularly critical for large NAS deployments where backing up terabytes or even petabytes of data is a daily necessity.

Here’s how an NDMP server contributes to robust data protection:

Optimized Performance: NAS filers are designed for high-speed file access and management. When they manage their own backups via NDMP, they can leverage their internal architecture to read and transfer data much faster than a general-purpose backup server might be able to. This dramatically reduces backup windows.
Reduced Network Congestion: In traditional client-agent backups, data had to travel from the NAS to the backup server and then potentially to the backup target. NDMP, especially with a local data path, minimizes this traffic. Even with a remote data path, the NAS is often better equipped to manage the direct transfer than a separate backup server coordinating the pull.
Simplified Management: Integrating NAS backups into a central backup software console becomes much simpler. The backup software communicates with the NDMP server as a single entity, rather than needing to manage individual agents on potentially hundreds of NAS filers.
Deduplication and Compression: Many NDMP implementations support inline deduplication and compression directly on the NAS device during the backup process, further reducing the amount of data that needs to be transferred and stored. This can lead to substantial storage cost savings.
File-Level Granularity: NDMP typically allows for granular restores, meaning you can restore individual files or directories rather than having to restore an entire volume or backup set. This is invaluable for quick recovery from accidental deletions or corruption.
Consistency: NDMP can help ensure data consistency, especially when dealing with applications that write data to files. Some implementations include options for application-aware backups, ensuring that data is backed up in a consistent state, even for databases or email servers residing on the NAS.

From my own experience, the difference in backup times and impact on NAS performance was night and day after we transitioned to an NDMP-based backup solution. What used to take an entire night and sometimes spill into the next business day could now be completed within a few hours, with minimal impact on our users accessing files during the backup window. This was a huge win for our IT team and our business operations.

NDMP Server Implementations: Vendor Specifics

It’s important to note that while NDMP is a standard protocol, its implementation can vary slightly between NAS vendors. Major NAS vendors like NetApp, Dell EMC Isilon (now PowerScale), Synology, QNAP, and others offer NDMP support in their enterprise-grade products. Each vendor might have specific NDMP versions supported, configuration nuances, and preferred backup software partners.

For example:

NetApp: NetApp’s Data ONTAP operating system has robust NDMP support, allowing for efficient backups to tape or disk using NDMP. They often integrate closely with leading backup software vendors.
Dell EMC Isilon/PowerScale: Isilon systems also provide comprehensive NDMP capabilities, enabling direct backups to various NDMP-compatible targets.
Synology/QNAP: While primarily known for SMB/SOHO solutions, many of their higher-end NAS devices also incorporate NDMP support, making them viable options for smaller businesses looking for efficient NAS backup solutions.

When choosing a NAS and a backup solution, it’s crucial to verify NDMP compatibility between the two. The backup software must explicitly support the NDMP version and features implemented by the NAS vendor.

Configuring and Managing an NDMP Server

Setting up and managing an NDMP server involves several steps, and while the specifics vary by NAS vendor, the general principles are consistent. This section provides a high-level overview and a checklist that IT professionals can use as a guide.

General Configuration Steps for NDMP:

Enable NDMP on the NAS: This is usually done through the NAS’s web interface or command-line interface (CLI). You’ll need to specify whether NDMP is enabled and potentially configure NDMP authentication credentials.
Configure NDMP Port: The default NDMP port is 10000. Ensure this port is open in your firewall between the NAS and your backup server.
Set Up NDMP User/Credentials: Create a dedicated user account on the NAS for NDMP operations with appropriate permissions. This account will be used by the backup server to authenticate with the NAS.
Configure Backup Destination: Ensure your tape library or backup target is properly configured and accessible to the NAS (if using a local data path) or the backup server (if the backup server is managing the remote data path).
Configure Backup Software (NDMP Client):
- Add the NAS device as a client in your backup software.
- Specify the NDMP server’s IP address or hostname.
- Enter the NDMP username and password created on the NAS.
- Select the appropriate NDMP connection type (e.g., direct, remote).
- Configure backup policies, schedules, and retention settings for the NAS data.
- Map the NAS storage to the correct backup media or destination.
Perform Test Backups and Restores: Crucially, always perform test backups of a representative dataset and then conduct test restores to verify the integrity of the backups and the restore process.
Monitor NDMP Operations: Regularly monitor NDMP backup job status, NAS system performance, and network traffic to identify and address any potential issues proactively.

NDMP Management Checklist:

Verify NDMP Enablement: Ensure NDMP is active on the NAS device.
Check Firewall Rules: Confirm that port 10000 (or the configured NDMP port) is open for communication between the NAS and the backup server.
Validate NDMP Credentials: Double-check the username and password used for NDMP authentication on both the NAS and the backup software.
Test Network Connectivity: Ensure the backup server can reach the NDMP server (NAS) and vice-versa.
Confirm Backup Target Accessibility: Verify that the backup destination (tape, disk) is visible and accessible to the NAS or backup server as required by the NDMP data path.
Review Backup Software Configuration: Ensure the NAS client is correctly configured in the backup software, with the right IP address, credentials, and NDMP settings.
Schedule Regular Audits: Periodically review NDMP configurations and permissions to ensure ongoing security and compliance.
Maintain NDMP Software Updates: Keep both the NAS operating system and the backup software updated to benefit from bug fixes and security patches related to NDMP.
Document Everything: Maintain clear documentation of your NDMP setup, including IP addresses, credentials, configuration settings, and troubleshooting steps.

As a seasoned IT professional, I can’t stress enough the importance of thorough testing. It’s not enough to just get a backup job to run. You absolutely must prove that you can restore your data. I’ve seen organizations suffer significant downtime because they assumed their backups worked without ever performing a real-world restore test.

Benefits and Drawbacks of Using an NDMP Server

Like any technology, NDMP comes with its own set of advantages and disadvantages. Understanding these can help IT professionals make informed decisions about their data protection strategies.

Advantages:

Efficiency: Significantly faster backups and restores compared to client-agent methods, especially for large NAS volumes.
Performance: Offloads backup processing from the NAS filer, reducing its load and maintaining file access performance for users.
Scalability: Well-suited for enterprise environments with a large number of NAS devices and massive data volumes.
Reduced Network Load: Minimizes network traffic, particularly with local data paths.
Simplified Management: Centralized control of NAS backups through backup software.
Vendor Interoperability: A standardized protocol that allows different vendors’ NAS and backup software to work together.
Data Integrity Features: Can include features like checksums and file system awareness for more reliable backups.
Cost Savings: Reduced reliance on backup servers and potentially less network infrastructure required can lead to cost efficiencies.

Disadvantages:

Vendor Support Varies: Not all NAS devices, especially entry-level or older models, support NDMP. The level of NDMP feature support can also vary by vendor and model.
Complexity: Initial setup and configuration can sometimes be complex, requiring specific networking knowledge and understanding of both NAS and backup software.
Cost: Enterprise-grade NAS devices that reliably support NDMP can be more expensive than entry-level solutions. Additionally, backup software licenses might be structured to account for NDMP clients.
Troubleshooting: Diagnosing NDMP-related issues can sometimes be challenging, requiring expertise in networking, the NAS operating system, and the backup software.
NDMP Protocol Limitations: Older versions of NDMP might lack certain advanced features found in newer backup technologies.
Security Considerations: Like any network protocol, NDMP requires proper security configurations to prevent unauthorized access to backup data.

When we first looked into NDMP, the initial setup was indeed a bit daunting. We had to coordinate with our NAS vendor and our backup software vendor to ensure everything was configured correctly. However, the long-term benefits in terms of performance and reliability far outweighed the initial setup hurdles. It’s a trade-off worth considering for any organization relying heavily on NAS storage.

NDMP vs. Other Backup Methods

To truly appreciate the value of an NDMP server, it’s useful to compare it to other common methods for backing up NAS data.

1. NDMP vs. Client-Agent Backups

This is the most common comparison. In a client-agent model, backup software installs an agent on the NAS filer. This agent then communicates with the backup server, and the NAS filer sends its data to the backup server, which then writes it to the backup target. Or, the backup server pulls the data from the NAS.

Key Differences:

Processing Load: NDMP offloads processing to the NAS. Client-agent backups place more load on the NAS’s CPU and memory, potentially impacting performance.
Data Path: NDMP allows for direct NAS-to-target transfer. Client-agent backups often involve the NAS sending data to the backup server first, adding an extra hop.
Efficiency: NDMP is generally more efficient for large data volumes due to direct data paths and NAS-optimized data handling.
Resource Usage: NDMP uses fewer resources on the backup server compared to managing multiple NAS agents.

2. NDMP vs. NFS/SMB Share Backups

This method involves mounting the NAS shares (via NFS for Linux/Unix clients or SMB/CIFS for Windows clients) onto a backup server or a dedicated backup client. The backup software then treats these mounted shares like any other file system and backs them up.

Key Differences:

Performance: Can be slower than NDMP as it relies on standard file sharing protocols and might not be as optimized for high-volume data movement.
Metadata Handling: NDMP has a deeper understanding of the NAS file system’s metadata, which can be crucial for consistent backups and efficient restores, especially with complex file attributes or permissions. Standard NFS/SMB backups might struggle with certain metadata.
Consistency: Achieving application-consistent backups for services running on the NAS can be more challenging with this method compared to NDMP implementations that may offer application awareness.
Complexity: While seemingly simpler, managing mounts and ensuring consistent access can become complex in large environments.

3. NDMP vs. Snapshots and Replication

Snapshots are point-in-time copies of a file system, and replication involves copying data to another location. While these are vital for disaster recovery and high availability, they are not typically considered direct replacements for traditional backups.

Key Differences:

Purpose: Snapshots and replication are primarily for rapid recovery from operational disruptions (e.g., accidental deletion, corruption, hardware failure). Backups are for long-term retention, compliance, and recovery from catastrophic events or widespread data loss.
Storage Efficiency: Snapshots are often space-efficient by only storing changes from the previous version. Replication copies entire datasets, which can be storage-intensive.
Ransomware Protection: While snapshots can be effective against ransomware if stored immutably or on separate media, a backup provides an air-gapped or offline copy that is generally more resilient to ransomware that encrypts primary and secondary storage.
Data Volume: NDMP backups are designed to move large volumes of data to a separate backup infrastructure for archival and long-term safety.

In my opinion, NDMP doesn’t replace snapshots or replication; it complements them. A comprehensive data protection strategy will often involve a combination: snapshots for rapid recovery, replication for DR, and NDMP backups for long-term retention and regulatory compliance.

Frequently Asked Questions about NDMP Servers

To further solidify understanding, let’s address some common questions about NDMP servers.

What is the primary benefit of using an NDMP server for NAS backups?

The primary benefit of using an NDMP server, which is essentially the NAS device configured to use the Network Data Management Protocol, is the significant improvement in backup and restore performance. NDMP allows the NAS filer itself to manage the backup process directly, reading data from its own file system and sending it to the backup destination (like a tape library or disk backup appliance). This is fundamentally more efficient than traditional methods where a separate backup server pulls data from the NAS, or a client agent on the NAS pushes data to a backup server. By offloading the backup tasks to the NAS, NDMP drastically reduces the burden on the backup server’s CPU and memory, frees up network bandwidth that would otherwise be consumed by data transfer to the backup server, and often results in much shorter backup windows. This is especially crucial for organizations with large amounts of data stored on NAS devices, where lengthy backup times can disrupt operations or even lead to data loss if backups cannot complete within their allocated windows.

Furthermore, NDMP enables a more direct data path between the NAS and the backup target. In many scenarios, particularly with local tape drives attached to the NAS, the data flows directly without needing to be routed through an intermediary backup server. This direct path minimizes latency and maximizes throughput. For remote data paths, while the data still traverses the network to a remote backup device, the NAS is still directly managing the transfer, often more efficiently than a backup server orchestrating the pull from multiple NAS devices. This performance gain translates into less downtime, more opportunities for backups to run, and increased confidence in the data protection strategy.

Why is NDMP important for enterprise NAS environments?

NDMP is critically important for enterprise NAS environments primarily because of the sheer scale and performance requirements of these systems. Enterprise NAS devices are designed to serve large numbers of users and applications simultaneously, often handling terabytes or even petabytes of data. Traditional backup methods, like client-agent installations that tax the NAS’s limited processing power, quickly become unmanageable and detrimental to performance in such environments. NDMP was developed precisely to address these challenges.

It provides a standardized, vendor-agnostic way for backup software to communicate with and control the backup processes on NAS filers. This standardization is key for large enterprises that might have NAS devices from multiple vendors. Instead of needing specialized, vendor-specific backup agents and tools for each NAS type, a single NDMP-compliant backup solution can often manage backups across a heterogeneous NAS environment. This simplifies management, reduces training overhead, and consolidates the data protection infrastructure. Moreover, NDMP’s efficiency in handling large data volumes, its ability to reduce network congestion, and its capacity for direct data transfer make it an indispensable tool for ensuring that enterprise-scale NAS data can be backed up reliably and within acceptable timeframes, thereby meeting stringent RTO (Recovery Time Objective) and RPO (Recovery Point Objective) requirements.

Does NDMP require special hardware or just software?

An NDMP server itself isn’t a separate piece of hardware in the traditional sense; rather, it’s the NAS (Network Attached Storage) device that has NDMP capabilities built into its operating system and firmware. So, while you don’t typically buy a distinct “NDMP server” as a standalone appliance, you do need a NAS device that supports NDMP. Major enterprise-grade NAS vendors, such as NetApp, Dell EMC (PowerScale/Isilon), and others, include NDMP support as a feature in their storage systems. This means the NAS hardware is capable of running the NDMP protocol, and the NAS’s operating system has the NDMP server software implemented within it.

On the other side of the equation, you need NDMP client software, which is typically part of a commercial backup application suite (e.g., Veritas NetBackup, Commvault, IBM Spectrum Protect). This backup software acts as the NDMP client, initiating and managing the backup jobs by communicating with the NDMP server on the NAS. In summary, NDMP relies on software running on both the NAS (the server) and the backup application (the client), with the NAS hardware being capable of running this NDMP server software effectively.

How does NDMP ensure data consistency, especially for applications?

Ensuring data consistency for backups, particularly for applications like databases or email servers that are constantly writing data, is a critical aspect of any backup strategy. NDMP implementations can contribute to this in several ways. While the core NDMP protocol is designed for file-level backups, many NAS vendors and backup software partners have developed advanced features and integrations that leverage NDMP for application-aware backups.

Here’s how it generally works:

Pre-freeze/Post-thaw Scripts: The NDMP client (backup software) can instruct the NDMP server (NAS) to run specific scripts on the NAS before initiating the backup and after it completes. These scripts can be used to quiesce applications – for instance, instructing a database to flush its cache to disk and temporarily stop accepting write operations.
Application-Specific Modules: Advanced backup solutions often have application modules (e.g., for Microsoft SQL Server, Oracle, Exchange) that work in conjunction with NDMP. These modules understand how to properly interact with the application to get it into a consistent state for backup. The NDMP protocol then facilitates the transfer of this consistent data.
File System Snapshots: Some NAS devices that support NDMP can also create very fast, space-efficient file system snapshots. The NDMP backup can then be initiated against this consistent snapshot of the file system, rather than the live, actively changing file system. This provides a consistent point-in-time image of the data for the backup process.
Metadata Awareness: NDMP’s inherent understanding of the NAS file system’s metadata can help in capturing the correct file attributes, permissions, and relationships, which is crucial for restoring applications correctly.

It’s important to note that the level of application awareness often depends on the specific NAS vendor’s NDMP implementation and the capabilities of the backup software being used. Not all NDMP setups will offer advanced application consistency out of the box; it might require specific licenses or configurations.

What are the typical NDMP ports used for communication?

The most commonly used port for NDMP communication is TCP port 10000. This is the default port specified by the NDMP standard for the initial connection between the NDMP client (backup server) and the NDMP server (NAS device). When the backup software initiates an NDMP backup or restore job, it attempts to connect to the NAS device on this port.

However, it’s important to be aware of a few nuances:

Dynamic Ports for Data Transfer: While the initial control connection is typically on port 10000, the actual data transfer might occur over dynamically assigned ports. This is especially true when the NAS is communicating directly with a backup target (like a tape library), or when the backup server is managing a remote data path. The exact ports used for data transfer can vary based on the NDMP implementation and the network configuration.
Firewall Considerations: For NDMP to function correctly, administrators must ensure that TCP port 10000 is open in all firewalls between the NDMP client (backup server) and the NDMP server (NAS device). If dynamic ports are used for data transfer, and they fall outside the standard range, firewall rules might need to be adjusted accordingly, or the backup software and NAS vendor might provide guidance on specific port ranges to open.
Vendor-Specific Configurations: While port 10000 is the standard, some NAS vendors or backup software might offer the option to configure a different port for NDMP, though this is less common. Always consult the documentation for your specific NAS and backup solution for definitive port information.

In summary, always plan to open TCP port 10000 in your firewalls for NDMP control traffic. If you encounter connectivity issues or data transfer failures, investigating dynamic port usage and firewall rules for those ports would be the next step.

The Future of NDMP and Data Management

While NDMP has been a cornerstone of NAS data protection for years, the landscape of data management is constantly evolving. New technologies like software-defined storage, advanced cloud-native backup solutions, and increasingly sophisticated data protection appliances are emerging. However, NDMP is not necessarily becoming obsolete; rather, its role might be adapting.

Many modern NAS solutions continue to support NDMP, recognizing its inherent efficiency for on-premises data. The protocol provides a proven, robust mechanism for handling large data sets. As cloud adoption grows, we might see more hybrid approaches where NDMP is used to back up on-premises NAS to a local staging area, which is then efficiently transferred to the cloud. Furthermore, vendors are continually updating their NDMP implementations to support newer features, better integration, and enhanced security.

The core principles that made NDMP valuable – direct data transfer, offloading processing, and standardization – remain highly relevant. Therefore, understanding what an NDMP server is and how it functions will likely continue to be a key skill for IT professionals managing enterprise storage for the foreseeable future.

Conclusion: Embracing the Power of the NDMP Server

In conclusion, an NDMP server is more than just a technical term; it represents a sophisticated approach to data management designed to tackle the unique challenges posed by Network Attached Storage. By enabling NAS devices to take control of their own backup and restore operations, NDMP offers unparalleled efficiency, performance, and scalability. For organizations that rely heavily on NAS for their critical data, understanding and leveraging NDMP can be a significant advantage, leading to shorter backup windows, reduced network strain, and ultimately, more robust and reliable data protection.

The journey from the struggles of manual tape backups to the streamlined efficiency of NDMP has been remarkable. It highlights how protocol standardization and intelligent design can solve complex IT problems. As data volumes continue to grow and the demands on IT infrastructure increase, the principles behind NDMP will remain vital. Whether you’re implementing a new data protection strategy or optimizing an existing one, a thorough understanding of what an NDMP server is and its capabilities is an invaluable asset for any IT professional.
