Data retention requirements are making long-term data archive nearly as critical as short-term restore needs. But many organizations are either inadequately archiving data or paying far more than they should to get the job done.
Catalogic DPX provides a cost-effective solution for long-term data archiving in NetApp storage environments. DPX archives data to disk, tape, and/or cloud in any combination, allowing organizations to grow and change based on their requirements, while also minimizing costs. DPX gives you investment protection while meeting your compliance needs for long-term data retention. Don’t retire your data: ensure that it is always available and usable when needed.
For a better understanding of the pros and cons of disk, tape and cloud as archive targets, consult our table Pros and Cons for Each Archive Storage Type.
NDMP (Network Data Management Protocol) provides an open standard for network-based backup of network-attached storage (NAS) devices. NDMP is a valuable tool for protecting NAS data, as well as offloading it for long-term storage to disk, tape or cloud.
Catalogic helped pioneer NDMP backups and remains a leader in supporting NDMP for NetApp and other compliant NAS systems. With Catalogic DPX, you can have an easy to use and extremely cost-effective standalone NDMP solution, or you can deploy DPX as a complete backup solution, with NDMP as a component.
With DPX, you get the storage flexibility to best meet your archival and compliance needs. DPX supports archive to disk, tape and/or cloud for long-term data archive. Data can also be tiered from one target to the next.
Backup to disk provides a near-line copy of data that can be accessed quickly for day-to-day data recovery needs (beyond what you might have available via primary NAS snapshots). With a storage efficient target device, such as Catalogic vStor, storage savings can extend on-disk retention time. vStor is a software-defined storage solution that lets you create a cost-efficient archival target using the storage hardware of your choice. Disk is often used as a short-term archive location, with data tiered off to tape or cloud for longer retention.
Backup to tape offers the most cost-effective solution for truly long-term storage that is measured in months or years. With DPX, file-level restore granularity is possible, allowing for targeted restores. Tape also allows for off-site storage in secure, audited bunker facilities, which can be critical for meeting compliance goals.
Backup to cloud provides an economic tape alternative also suitable for long-term storage when tape is not desirable. Cloud backup is similar to tape functionally, but data storage is outsourced to a third-party cloud vendor. While effective, a careful review of cloud provider data access costs is warranted, especially if many restores are expected.

DPX offers highly affordable licensing for NDMP backups that are used for archiving data. Many organizations license NDMP backups as part of their overall capacity licensing for their backup software. However, because file data volumes tend to be large and constantly growing, file backup and archive may comprise a large percentage of your total backup licensing costs. By switching to Catalogic DPX for your archive needs, you can keep the remainder of your backup environment intact while gaining significant cost savings. And because NDMP backups are based on NetApp storage devices, the transition is easy to manage. You aren’t faced with re-configuring backup jobs for hundreds or thousands of servers.
There is no single best choice for archive data: it all depends on your organizational requirements for things such as retention time, RTO, CAPEX vs. OPEX spending, and so on. This table summarizes some of the pros and cons of each major archive storage type.
Catalogic engineering and support organizations have been working with NDMP from its inception. We have many experts on staff with a long history of supporting NDMP and other backup technologies. With Catalogic, you can rest assured that your critical archive deployment is in the best possible hands.
DPX supports hardware encryption for tape drives attached to a NetApp device. With hardware encryption, the tape device encrypts data as it is written to the tape. Encryption keys are generated through the DPX keyring function. Restoring from encrypted tapes is transparent.
Archiving data for long-term retention is an integral part of your data protection strategy. Compliance, audit and legal requirements demand long-term retention for many types of data. Catalogic is a leader and innovator in this technology. We can easily add data archiving to any existing data protection strategy to assist in completing your overall requirements in a cost-effective manner.
