We already have our server set to Raid 0 and want external backups, so we can
alternate the drives to take home. I think I am just going to get 2 external
HDD, each 1.5 or 2 TB, and plan on having 2 volumes each.

so what's the benefits of using a diff if I have all the increments? The diff
seems like it will only do a diff from the full not another diff, is that
correct? I was thinking Full + Incremental for 3 months. Initially I was
thinking Full + Inc. Tue-Sun then a Diff on Mondays, but I didn't see any
benefit from doing a diff on a weekly basics. If the diff was doing a diff of
the diff/full then it would make more sense.
Thanks for you feed back
