You have a file based storage array available with a capacity of say 6 TB, and you have to back up 20 clients.

Lets say I’m going with the default Full/Diff/Inc weekly schedule and that I’ve had an arbitrary retention time of 1 year on fulls 6 months on diffs and 1 month on incrementals.

What strategies would you employ to manage disk space, estimate growth etc.

Is there a missing variable here, witch is the size of your full backups?

As for strategy I like to use GFS Rotation like explained on this diagram: http://www.bacula.com.br/?p=2271
