In a nutshell:
- SBS03 server with Backup Exec 12 installed.
- Two USB drives, each 1TB.
- USB drives are swapped weekly.
A weekly full backup and 4 days of subsequent backups just about fills a drive. After swapping a drive, the next Weekly Full job will throw an alert about low space and we have to manually clean out the drive so that the backup will finish. I know there's a way to dial this in so that Backup Exec will manage that space for us, but I can't seem to hit the right settings!
The media set properties for "media set periods" are currently at:
- Overwrite protection period: 13 days
- Append period: 1 hour
The weekly job is set to "Append to media, overwrite if no appendable media is available"
[added later] Tools -> Options -> Media Management had "media overwrite protection" at the default "Partial" setting.
What other settings am I missing to get this working without intervention?
