Avamar backup and recovery software reduces network bandwidth and backup times by using variable-length subfile segments. Each subfile segment has a unique hash identifier, which the Avamar system uses to determine if a segment has been previously backed up. The use of a unique hash identifier enables Avamar to perform source-based deduplication. Subfile segments that have been backed up are not backed up again, saving network bandwidth and reducing backup times. Unique subfile segments that have not been backed up are compressed and sent to IDPA for protection.
Extensive performance testing by Enterprise Strategy Group (ESG) demonstrated that IDPA delivers significantly reduced backup times. ESG compared an IDPA solution to Vendor A in progressively protecting a mixed-workload infrastructure that increased in scale by 100 virtual machines (VMs) with each test iteration. At the 400 VM count, IDPA showed a 64 percent faster backup time than Vendor A. The faster backup times were due in part to the significant source-side deduplication. In the lab review, the IDPA solution transferred 74 percent less data over the network than Vendor A.
IDPA DP4400 also provides target-based deduplication by integrating the Data Domain deduplication storage system. The system performs up to 99 percent deduplication processing in CPU and RAM. Because performance is not based on disk, the Data Domain system can accelerate and protect more backups in parallel. The deduplication occurs inline, which means that deduplication analysis is done in real time and only unique data is stored to disk. In a cost-efficiency analysis, ESG found that storage capacity cost over a 3-year period was 57 to 81 percent less with IDPA solutions than with comparable data protection solutions.
Fast backups are critical for S2D Ready Node ecosystems, but many businesses mandate multisite recovery. With IDPA DP4400, administrators can schedule jobs that copy backups to other data protection solutions in the IDPA family, including other Data Domain systems.
Restoring a VM is simple and fast, enabled by a few clicks in IDPA System Manager. Advanced restore capabilities include restoring backups to a new VM, determining if the VM should be powered on or off, and choosing to restore backups to a new host or cluster. You can also restore individual files from a VM.
