Hi,
Use your latest Timeshift snapshot, booting from Linux Mint ISO on a DVD or USB disk (Timeshift is on Mint ISO and you can launch it from the DVD / USB key).
Or use your latest system image, booting from Foxclone / Clonezilla on a DVD or USB disk.
If you have no backup, perform a fresh install. And think to the way you will make backups.
Here is what I do:
- I have an USB key, made with Ventoy, on which are Foxclone, Linux Mint 20.3 Mate and System Rescue ISOs. I can boot on this key and choose the ISO I want to launch.
- My "/" and my "/home" are on separate partitions.
- I use an external USB disk for backups.
- "/" backup:
* I take an image with Foxclone every two or three weeks, or before big changes (Mint 20.2 --> 20.3...),
* I take a system snapshot with Timeshift every two days, I keep two; it is fast, Timeshift is a differential backup software.
- "/" restore:
* if possible, restore with Timeshift, from working system;
* if not possible or not working, restore with Timeshift, from Mint 20.3 ISO;
* if not possible or not working, restore with Foxclone, and update with Timeshift, from the system.
- "/home" backup:
* I use FreeFileSync, launched in super user mode to keep files attributes (launched with "sudo -H", it is not very orthodox, but it is a no risk replacement of obsolete gksu and gksudo commands).
* I make a home backup every day; it is fast, FreeFileSync is a differential backup software.
- "/home" restore:
* with FreeFileSync or file manager (caja with Linux Mint Mate).
System Rescue is there for repairs.
Of course, there are other ways to do.
