This commit introduces two main improvements: 1. **Backup Deletion:** The user can now delete system and user backups from the "Backup Content" view. 2. **Improved Exclusion List:** The `.cache` directory is now excluded from backups by default, which should prevent "file has vanished" warnings from rsync.
