I was trying to set up a family member up with Linux as a windows replacement. I installed MX Linux xfce on their laptop with separate “/” and “/home” partitions.
Through a comedy of errors, the following occurred:
- On day one, Timeshift was configured to take weekly snapshots of the system files AND their user home folder.
- The initial timeshift snapshot was begun, and then cancelled when they discovered that home files aren’t the intended target, but they noticed growing snapshot files, indicating the cancelation wasn’t complete.
- NCDU was used to remove the files in /home/timeshift
- The family member’s only copies of three days of paid work in a writing program called Bibisco (Java app) disappeared after reboot
The system was rebooted twice before the cause was discovered and shutdown with minimal (5min) use.
I’ve never done any ext4 data recovery, but the tools in Kali seem geared toward common and known filetypes (pdf, jpg, etc).
Should I be looking to restore the timeshift files, or the writing documents (with .bibisco2 file extensions)?
Is this a lost cause?
I suspect the files were actually in a timeshift snapshot, so when those files were deleted, so were the files.
I’ll give your links a thorough read, thanks!
From my understanding, files cannot be directly stored only in a timeshift snapshot – they must be first stored on the disk and only then timeshift can make a backup inside the snapshot. But I have never used timeshift myself, maybe I just completely misunderstand how it works.
Deleting the snapshot files lost considerable data including all files created after the aborted snapshot. The reboot that initially uncovered the problem led to a boot in “basic” xfce, and searching for the work files in read only mode from live boot shows no files/folders created in /home/username after the snapshot. It seems to have behaved like a VMware snapshot that had files living in the snapshot.
