I have a new install BE 2015 and I am running dedupe NA filer backups for a few weeks. All is good. But I need to offisite a full backup to tape(s) once a month. I have a few full backups to the dedupe storage and taking one backup as an example, its 3TB. When I duplicate to tape its like 300MB. Is this correct? It seems tiny compared to the backup size of 3TB. I am a bit concerned that I am not taking anything to tape,
I was under the impression that when duplicate to tape was conducted (from a dedupe backup) that the data would be re-hydrated as in back to its original size. But then in the back of my mind I am thinking that this could be right.
Not a problem. Just a bit concerned.
I could of course just do a full backup to tape one week in four. But this doesnt seem right somehow.
Can anyone confirm if this is right or not.
Chris.
