Not Deleting Old Backups on Removable Drive
I am using a backup scheme set to retain only two backups. I am using a removable USB drive. I periodically swap the backup drive with an identical drive so I can store the backup drive in a fire-proof box. But when I do Backupper doesn't delete the old backups from the previous use of the drive. I currently have backup files on the drive from 9/8/2019, 9/9/2019, 10/6/2019, and 10/8/2019. My last backup failed because there was not enough space left on the drive.
