From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Solved] Data recovery of unique file type(s) (lemmy.world)

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?

Edit: Thank you everyone for your helpful comments. In the end, time was against us and the choice was made to reinstall. After I realized the document files are just json, I looked in three Kali carving apps and the photorec app, and there were no files to recover. The freah install now has eclone set up to push regular updates from the bibisco folder to the cloud. Lesson learned.

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.
