<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed

- Backup on: verified that backup isn't executed
- Backups off: Verified that only one backup is executed
- Verified that backup is located in the expected path
- Auto delete is set to "never": verified that no backups are deleted
- Auto delete is set to "based on count": verified that backups are
deleted according to count value
- Auto delete is set to "based on age and count": verified that backups
are deleted according to days and count values
- Verified that files without the backup pattern aren't deleted
- There is also adequate test coverage for these scenarios 🚀
