 |
|
Having hastily/accidently deleted many files.. i searched long and hard for an undelete solution. I struggled to find any other howto on the net. I have this to share, but was unable to verify it. Im my case it did restore a file that was about the same size, but the file was corrupted. I hope that it brings your files back, should cost you nothing to try it.
Commands needed: extundelete, debugfs. The former I definitely merged but was masked. The latter may have been existing in my Gentoo install.
Procedure:
| Code: | $DEV = storage device where deleted file was
# Remember to stop any processes that are attached to this volume before continuing
mount -o remount,ro <$DEV>
debugfs <$DEV>
In Debugfs:
cd <directory where deleted file/dir was>
ls -d
# Note the inode of the deleted item that comes up in the list
quit
Restore:
cd <directory where you want the file recovered to>
extundelete --restore-inode <inode num above> <$DEV>
#If your file recovered, then:
mount -o remount,rw <$DEV>
# Start up processes that use this volume
# Else, you should leave the volume mounted RO and try to find some other recovery methods
# This method is exhaustive, make sure you have plenty of space on the target
extundelete --restore-all <$DEV>

| There's a few other options in the tree too, in app-forensics/ — magicrescue and foremost have both come in useful. |
