I just noticed a really weird thing about our incremental backups being
run from Veritas Netbackup DC 4.5 to our Netapp 960 (6.4.2P6). I assume
this has been going on for a long time. No matter if we select Incremental
Differential Backup on weekdays or Cumulative Differential Backup on weekends,
both seem to run a level 1 backup on the filer. This
results in all changes since the last level 0 (Full) backup to be written,
which I interpret to be Cumulative. Once in a while (on a random day of
the week), a real Incremental backup (level 2) will be performed. This is
verified by examining the /etc/backup logs on the filer, which show the
level of dump being used. Examining the amount of data being backed up
also shows a steady increase in the Incremental backups, indicating that
they are all backing up the same data from the last Full. This looks like
a Veritas bug, and I have found no reference to it on the web. If anyone
has encountered this, please advise!
Thanks,
