[Bacula-users] Lets open up a discussion about estimating required space for backups.

Hi,
This has plagued me for a while… [ and while it sounds a lot like a home work
question… its actually just be being curious and reaching out :) ]
Imagine a scenario similar to this:
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.
I guess there are a few scenarios
1 : eventually you will find out that your arbitrary limits are just not
possible to accomplish with given diskspace.
OR
2: it will work fine and things will get recycled fine.
Is there a good way to plan ahead?
Thanks!
Jeff. (Runkle on irc #bacula)
