[solved] reverting from 20 to 19.3 via timeshift

Post by elmarts »

Since Mint 20 is giving me problems with gnucash, updating, etc. I'm considering reverting back to a timeshift 19.3 backup. Is there anything I should be aware of when I do this - it's my first time attempting to actually "use" timeshift to back up.

Just today I restored the LM19.3 and then returned back to the LM20 with Timeshift snapshots.
Before restoring anything I backed up my home catalogue with all dot files and the rest. Although in theory this is not required.

Then I restored my snapshot with 19.3LM on my main partition over current installation of LM20. This is how it supposed to be done. I noticed the / filesystem was mounted read-only (don't know why). But I logged in through text console and remounted it read-write. And then system started GUI. At the same time I noticed the system was restored not completely the same it was before. I don't know what exactly was wrong but my "passwords and keys" application couldn't to show keyring contents.

Then I loaded the system from usb-stick in live session. You should prepare working live usb-stick! I formatted my main partition <<< Do you remember to backup your home first? And the restored LM19.3 snapshot from live session. During restoration I created user catalogue and extracted tar with my home to it. After restore was completed I rebooted to my LM19.3. It was the same as before.

I returned to the LM20 back in the same way as I restored LM19.3.

Personally I prefer Clonezilla as it runs from bootable media and it gives you a 100% restore back to the point of when you initially imaged it. so anything changed after that will be gone. so even if a upgrade to v20 completely hosed your system, with Clonezilla it will be like that never happened. but you need a additional hard drive (or partition or some external device) to store the image file and it does not require EXT4 like Timeshift does either.

I realize my comments won't help you in your current situation but I suggest it in the future.

I used Clonezilla for years, and now use Foxclone. Made by one of our very own Members.
As for the OP, my message is to expect the Upgrade to fail, then if it doesn't great.

Hmmm, you're saying that one should not attempt to restore from a timeshift image while running the OS that is actually to be replaced, I take it. Only restore via timeshift when booting from external media (DVD, USB, or whatever). Did I understand you correctly? Also, I should make a complete copy of my home directory via the backup tool, since that may be destroyed.

You can try from the OS and if it fails, do it from live. I suggest having Timeshift configured as the picture so all but you data in Home is included in the snapshot.

It's not necessary. But in my experience I prefer to restore to clean formatted partition. Therefore I have to run the OS not that is actually to be replaced.

If you format your partition with new filesystem then old filesystem will gone. So you should take care of your files in home because Timeshift don't care about it by default.
Else your files will not be touched by Timeshift if you restore snapshot over current filesystem.

I have not investigated this situation deeply. I just noticed that the application "Password and keys" did not work correctly if you restore the system over running one. So my option was to restore on clean filesystem. And it worked.

I just reverted back to LM19.3 Mate from LM20 Mate via a Timeshift backup.
I was running LM20, then opened Timeshift, then selected the LM19.3 (tricia) backup, then clicked Restore.
Timeshift restore comleted, laptop rebooted.

I just bit the bullet and did the reversion - and as you say, it went flawlessly. thanks for the hand holding. Now running Release Linux Mint 19.3 Tricia 64-bit Kernel Linux 5.0.0-20-generic x86_64 MATE 1.22.2 :) Gotta change my sig though.
