![]() ![]() During backup files transformation the same blocks are read and then written back to the appliance where they are de-hydrated (deduplicated) again. Note: "Re-hydration" is the act of restoring the original blocks in a non-deduplicated form. Such operations require significant time and I/O. Unless you are using DDBoost protocol on EMC DataDomain storage or Catalyst on HPE StoreOnce, you should configure primary jobs for forward incremental with active full backups - since jobs with transformation will require block "de-hydration" and then "re-hydration" on the storage. Deduplication Appliance as a Primary Backup Repository ![]() Using a Deduplication ApplianceĪs a storage-agnostic product, Veeam Backup & Replication can use any deduplication appliance as a repository in different use cases: primary backup repository, backup copy repository, and Virtual Tape Library (VTL) container. ![]() For this reason we recommend to use these devices mainly as secondary targets, where parameters like price per GB are more important than restore performance. However, any random read I/O may suffer from re-hydration processes required during restores. Deduplication applied to storage is a technique aimed at reducing the storage space consumption.ĭeduplicated storage systems are often optimized for write operations and can offer rather high ingest rates. ![]()
