Timeshift snapshots disappeared

All timeshift backups prior to this date just disappeared. Computer was freezing up unexplicably for minutes at a time, then resuming, then freezing again. Only mouse pointer working. When I decided to restore snapshot, noticed the disappearance. Wonder if issues are related.

Already ran “timeshift --check” . It detected a few incomplete snaptshots and removed then, but did not restore my snapshot list.

Any idea what could have happened?

For a backup program, that is a pretty major issue. Thanks !

By the way, is there a way to know if what disappeared has been only the snapshot list or if the snapshots themselves were wiped away?

You can mount the volume where the snapshots are stored at a directory ─ say /mnt ─ and then check whether the snapshots are still there. I suspect that they will be, because it takes a long time for timeshift to delete a single snapshot, let alone all of them.

So it’s probably just the list, but better check, just to be sure. :wink:

Thanks a lot. Pretty newbie here. If that would not be asking too much, I would be glad to know what command line mounts the snapshots. :grimacing:

Well, it depends on what partition you are storing your snapshots on. In my case, I keep them on /dev/sdb2, and so on my system, the command would be…

sudo mount /dev/sdb2 /mnt

Then as you look through /mnt, you will find a directory named /mnt/timeshift, and in it, a directory /mnt/timeshift/snapshots. Here’s the output from my own system, picking my most recent backup.

The directory localhost in the above terminal output is the actual directory where the files and directories (“folders”) of the snapshot are located.
