What is timeshift?
creating a snapshot & scheduling
In order to make a snapshot, simply click "Create". You can also make scheduled snapshots by going to the settings -> "Schedule" and set the amount of daily, weekly, monthly, hourly, backups, or even set to backup in boot time.
Keep an amount of snapshots
Additionally, you may set the amounts of how many snapshots of each kind you would like to keep. so you could have 2 daily snapshots and 1 monthly kept all the time. You can do this by going to the settings -> "Schedule",and set the values there.
Restore the System
There are multiple ways to restore the system: * Click the "Restore" button and accept. * If the system is not bootable, you could use a live system off of a USB stick (using ubuntu is recommended), install timeshift on it, and restore the main system from there.
You may get the .deb file from the github page releases and use:
