Deduplication storage feature is one of the most useful feature in Backup exec which save a lot of storage space and reduces cost.
Deduplication storage eliminates duplicate data in the storage system and writes only the unique data which reduces the backup windows and saves a lot of space in the storage and ultimately save money as well.
While you create a backup job for Dedup storage you get to choose two option : Client side Dedup and Server side Dedup. The recommended way is client side dedup where data is written and processed on the client server which is the remote server and then only unique data is sent across the network to write on to the dedup storage.
This process also reduces network load and minimizes backup window and it does not use the resources of backup server so that backup server can complete other tasks smoothly. We’ll discuss in detail in the separate blog.
