Deduplication and Rehydration

[tolinrome]

Hello,

I'm trying to understand what rehydration is and how it works, especially when it comes to raw data and bk files. Just general information about it.

Thanks.

In simple terms Rehydration means "un-deduplicating" (well there's no such word, but it helps understand)...

Backup Exec lets you copy deduplicated data from an OpenStorage device to tape for long-term or off-site storage. When data is copied to tape, it is rehydrated. In other words, the files are reassembled into their original form and are not deduplicated.

Rehydrate is it the operation to compare the content of an imgae to Netbackup Catalog? 

Thank you
