What is the relationship between replication and data deduplication?
They are related in that with data deduplication, you can replicate things that you have not been able to before, such as regular backups. Replication historically has been at the volume level or the file level. You’re replicating a volume, file or database at its primary location. Then if you were to back up that database to a disk array, then replicate that disk array without deduplication, you would be replicating a significantly larger amount of data than if you were replicating it from the source. Dedupe allows you to back up that data to a disk using dedupe methodologies, and then because dedupe actually eliminates redundant blocks, it can then allow you to replicate that backup to another location. This was something that was only possible in the smallest environments up until now. W. Curtis Preston (a.k.a. “Mr. Backup”), Executive Editor and Independent Backup Expert, has been singularly focused on data backup and recovery for more than 15 years. From starting as a backup admin
