Full Backup Times Reduced From 108 Hours to 36 Hours, Deduplication Reduces Data to Maximize Disk Space
Stammer said that prior to installing the ExaGrid system, weekly full backups would run from Friday night at 7:00 p.m. to Wednesday morning. Initially, active full backups to the ExaGrid system would run approximately 60 hours but now run 36 hours after implementing the ExaGrid- Veeam Accelerated Data Mover.
“We saw a huge improvement in our backup times when we switched over to the Veeam- ExaGrid solution, but when we started using the Data Mover, we gained even better results,” said Stammer. ExaGrid has integrated the Veeam Data Mover so that backups are written Veeam-to-Veeam versus Veeam-to-CIFS, which provides a 30% increase in backup performance. Since the Veeam Data Mover is not an open standard, it is far more secure than using CIFS and other open market protocols. In addition, because ExaGrid has integrated the Veeam Data Mover, Veeam synthetic fulls can be created six times faster than any other solution. ExaGrid stores the most recent Veeam backups in an undeduplicated form in its Landing Zone and has the Veeam Data Mover running on each ExaGrid appliance and has a processor in each appliance in a scale-out architecture. This combination of Landing Zone, Veeam Data Mover, and scale-out compute provides the fastest Veeam synthetic fulls versus any other solution on the market.
Veeam uses changed block tracking to perform a level of data deduplication. ExaGrid allows Veeam deduplication and Veeam dedupe-friendly compression to stay on. ExaGrid will increase Veeam’s deduplication by a factor of about 7:1 to a total combined deduplication ratio of 14:1, reducing the storage required and saving on storage costs up front and over time.
