Backup data stores often contain a massive amount of redundant data which can tax network, disk and processor resources. Deduplication technologies help reduce backup storage requirements and allow jobs to complete within shorter time windows. Simply put, deduplication allows enterprises to retain vital data at a lower cost.
File-based deduplication removes duplicate copies of data at the primary storage array. For data sets with low rates of change, block-based deduplication uses software algorithms to scan files, detect and remove repeated block-level patterns of data, and replace them with pointers in a catalog. The decision whether to use source (i.e., server) or target-based (backup storage target or appliance) deduplication depends upon your current backup processes and other factors.
Dell™ offers a variety of software and hardware platforms that integrate deduplication with backup software. To help you evaluate your options, Dell Storage Consultants have the expertise to assess your environment, size your requirements and help you make the best decision to gain the maximum benefit.
