Today, the approach to data protection is changing. Backup software allows for in-place recovery and the ability to instantiate data volumes directly on backup storage, which allows organizations to significantly reduce recovery time. As a result, the performance of backup storage hardware is more important than ever. At the same time, backup software can scale to manage petabytes of backup data already stored, so it is also critical to keep the hardware costs associated with storing data. Finally, new regulations require that backup data must meet both retention requirements and new data privacy requirements.
Software applications such as Veeam's Availability Platform provide organizations with the functionality to meet all of these requirements. The challenge for organizations is to update the hardware components of their data protection architecture so that the software can fully deliver on its promises.
Components of a Modern Data Protection Infrastructure
Layer 0 - Snapshot-based Instant Recovery
Snapshots have been used as a form of data recovery for over a decade. The problem is that snapshots are unorganized and are typically not integrated into the data protection process. Due to the lack of integration, most organizations retain only a small number of snapshots. Storage system snapshots need to be integrated with and managed by data protection software so that IT managers get the truth when trying to determine the most appropriate data sets for recovery.
Once the snapshots are integrated and managed by the backup solution, the backup solution can combine the snapshot dataset with "recover in place" capabilities to provide immediate recovery capabilities. More critically, the recovery occurs on the same storage system as the original dataset, so it is properly optimized for performance and runs on the same production network. The result should be a seamless application performance experience.
The challenge with several storage systems on the market that can retain a virtually unlimited number of snapshot copies is finding the right data in all those snapshots. By integrating snapshots with a backup solution, those snapshots can be searched through the search function of the backup solution.
The downside of using snapshots as a data protection solution is that snapshots are dependent on the primary storage system and its data volumes to remain available. If the storage system fails, the primary volume and its snapshots will also be unavailable. For these reasons, IT administrators should use snapshots in conjunction with other data protection layers.
