GlouOSSnapshots & rollback
GlouOS takes a snapshot before every update, so a bad change is never permanent.
How snapshots work
A snapshot is a point-in-time copy of your system files. GlouOS creates one automatically before each update, and you can take one manually at any time from the Control Center.
Rolling back
If an update causes trouble, pick the previous snapshot from the boot menu (or the Control Center) and your system returns to exactly how it was, with nothing to reinstall.
Managing snapshots
Old snapshots are cleaned up automatically to save space. You can pin one you want to keep, or delete ones you no longer need.
