Backups and Restores are ‘So Quick’
BearingPoint installed an ExaGrid system at its primary site that replicates data to another ExaGrid system installed at its disaster recovery (DR) site. Weidacher performs daily backups in addition to regular snapshots. “We have a mix of physical and virtual servers to back up,” he said. “We’re backing up about 300TB of data, everything from VM images, production server source files, and source code file servers.”
Weidacher has been impressed with the speed of the daily backup jobs. “Our backups are so quick now, it’s hard to even compare them to the backups we had to the tape library. ExaGrid backs up the data so much faster; some of our backups are finished in under a minute and our largest backup jobs are finished within five hours.” Switching to an ExaGrid system has resolved the issue with slow restoration of data that Weidacher had experienced with the tape library it had used in the past. “It’s very convenient to restore single files using ExaGrid and the restore times are very fast,” he said.
“Our deduplication ratios with ExaGrid are quite high, between 6:1 to 74:1, depending on the type of data,” he added. ExaGrid customers can simply transfer file system data from Unix or Linux systems to the ExaGrid server. ExaGrid delivers a 10:1 to 50:1 deduplication ratio and can replicate the deduplicated data to an offsite disaster recovery location as well as report deduplication ratios by the individual Unix/Linux backup jobs.
ExaGrid writes backups directly to a disk-cache Landing Zone, avoiding inline processing and ensuring the highest possible backup performance, which results in the shortest backup window. Adaptive Deduplication performs deduplication and replication in parallel with backups so that an RTO and RPO can be easily met. Available system cycles are utilized to perform deduplication and offsite replication for an optimal recovery point at the disaster recovery site. Once complete, the onsite data is protected and immediately available in its full undeduplicated form for fast restores, VM Instant Recoveries, and tape copies while the offsite data is ready for disaster recovery.
