BE 2012: Rolling full backups question
Hi there,
I'm having some trouble with the setup of a backup job within BE 2012; what I'd like to happen is for full backups to run on a daily basis to 4 "daily" tapes (M,Tu,W,Th); these backup sets would be retained for a month and Friday I have a set of 5 tapes that I would cycle every week. Essentially, these are two different media sets.
The problem I'm having is that the backup sets don't seem to be overwriting the older "expired" data; I seem to be confusing the overwrite protection period, append period, and expiration period. Even when the backup sets aren't configured for expiration, if the overwrite protection period for the tape is passed, it seems that all of my backup sets are overwritten.
What does the overwrite/append protection period need to be set to for this to function properly? How do I ensure that tapes are "recycled" without losing my non-expired backup sets?
Thank you in advance!!!
