I have been using veritas for a while now backing up to tapes. I have never had a problem until I started backing up to disk. I have an external USB disk and backup to it using veritas, I do a full on Friday and diffs for the weekdays mon-thurs. Do I set the full to overwrite and the diffs to append?
I want to be able to inventory the drive and catalog the job to restore at any time. I have to keep changing out the drives because we have to keep the backups for 5 years each week we use a new drive. Cost is not an issue for us.
Should I be setting the Overwrite protection period? and to what?
