WHITE PAPERVMware Data Backup and RecoveryData Domain Deduplication Storage Best Practices Guide VMware sites create more storage to manage and protect than their physical counterparts. By making it much simpler to multiply servers, it also becomes more likely that their storage footprints will multiply. This is significantly visible in backing them up. For example:
Fortunately, with Data Domain systems as the target storage for VMware environment backup, those similar files would be deduplicated at high speed. All of the common data sequences are pooled to the smallest reasonable storage footprint, for on site protection and replication to a DR site. When using Data Domain storage with well-understood best practices for backup and taking snapshots in VMware, a deployment can simplify management of consistent images. Once stored, the images are ready to restore, locally or, with optimized deduplicated replication, at a remote DR site. This paper describes best practices for managing these synergistic technologies together. Where most file system backups result in 10x-30x data reduction on a Data Domain system, VMDK-inclusive backups commonly offer 40x to 60x reduction. |
