Question : veritas append or overwrite?

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?

Thanks

The msi should hold the paths for any external dependencies and be relative or absolute, depending on how you have things configured.

IF you do any special processing, you will actually want to have people run the setup.exe and not the MSI due to UAC issues.
