[Question] How to offline restore master snapshot of btrfs system? #315

Closed m1karii closed 1 day ago

m1karii commented 3 days ago

I use EndeavourOS with btrfs backups and my PC crashed mid full upgrade resulting in it not being bootable. I was able to select snapshot I manually created prior in grub and boot into it. I tried restoring it and here comes the problem: timeshift seems to restore selected snapshot over currently running one not over the master one resulting in it doing practically nothing (overwriting itself) and now I have to select to boot to this specific snapshot in grub every time i turn on PC. How do I restore selected snapshot over the master one? or overwrite the master one with the current one?

Boot from a live USB system and restore it.

can you please elaborate on that @teejee2008 ? I ve tried chrooting into the system however the timeshift on the master snapshot wont even start due to the following error: 

timeshift: symbol lookup error: /usr/lib/libvte-2.91.so.0: undefined symbol: ucnv_toUnicode_74

the README mentions "offline restore" however I seem to be unable to find more details about it

Write the Linux Mint ISO to a USB drive and boot from it. Run Timeshift from the live system. Select the system drive and the snapshot to restore and restore it.

worked. thanks. In case there happens to be someone with the same issue decade from now: you do NOT want to restore /home subvolume.
