Today I accidentally deleted all files in my /home/Documents directory and had to recover some of them.
Luckily, there’s an easy way with the extundelete program.
First of all, umount the target partition:
sudo umount /home
Note: if you get the ‘device is busy’ message, you can add the lazy option:
sudo umount -l /home
Then install extundelete (if you don’t have it already):
sudo apt-get install extundelete
Now recover the files that were deleted from that directory, for which you need to specify the mount point (use df -h for that):
sudo extundelete --restore-directory /home/Documents /dev/sda5
This will create a RECOVERED_FILES directory with all the file structure of the deleted directory, containing the files that could be restored.
Finally remount the target partition:
sudo mount -o remount,rw /dev/sda5 /home
