7.1.4_P1

I noticed my backup partition was full and i decided to blow it away and start with new/clean formatted partition. (only had a few days on disk and yesterdays nightly to tape is still on hand)

as zimbra:
zmbackup -f -a all

Process starts, it shows the new full dataset with zmbackupquery. i see it going through accounts. Shortly after, maybe 10-20 accounts, it stops.

Is there anything i need to do before starting from scratch with a new backup partition?
