| | **Update: deja-dup is still not the perfect backup solution, but it is close. At least, I can tell my relatives to use it, though in case of needed restore they might need my help.** |

| But first, a list of my requirements, since yours may differ: | But first, a list of my requirements, since yours may differ: |
| * ability to backup through smb | * ability to backup through smb |
| * ability to browse backups and restore single files | * ability to browse backups and restore single files |
