I have a Backup to Disk folder (on a USB Drive) which does a full backup Monday through Saturday, inclusive. It runs at 23:00 each day, but the drive is only large enough to fit 5 backups. (Each backup is about 360GB, the drive 1.81TB.)
If I set the Overwrite protection policy to 1 day, by the time it gets to the Saturday backup, Monday's through Friday's backups are all overwriteable. How does BackupExec see this? Will it just overwrite anything from that selection, or will it still only overwrite the oldest? That is, will it overwrite Monday's, then when it runs again on Monday, will that overwrite last Tuesday's, then on Tuesday will that overwrite last Wednesday's etc.
Or is that not how it works?
If not, how can I set it up so that it does work like I have described above, keeping in mind I can only fit just 5 onto my drive?
I have a single job, all backing up to a single device called Back to Disk, and a single media set with OPP of 1 day. This is a client's setup, and as much as I imagine you will suggest it's awful practice the way I'm doing this, they don't want it changed, but just working so they don't need to delete the previous day's backup everyday so that it will append. (It is set to append first, then overwrite.)
