extundelete Package Description
extundelete is a utility that can recover deleted files from an ext3 or ext4 partition. The ext3 and ext4 file systems are the most common default file systems in Linux distributions like Mint, Mageia, or Ubuntu. extundelete uses information stored in the partition’s journal to attempt to recover a file that has been deleted from the partition. There is no guarantee that any particular file will be able to be undeleted, so always try to have a good backup system in place, or at least put one in place after recovering your files.

extundelete – Utility to recover deleted files from ext3/ext4 partition
Usage: extundelete [options] [--] device-file
--version, -[vV] Print version and exit successfully.
--help, Print this help and exit successfully.
--superblock Print contents of superblock in addition to the rest.
If no action is specified then this option is implied.
--journal Show content of journal.
--after dtime Only process entries deleted on or after 'dtime'.
--before dtime Only process entries deleted before 'dtime'.
--inode ino Show info on inode 'ino'.
--block blk Show info on block 'blk'.
Restore the file(s) with known inode number 'ino'.
The restored files are created in ./RESTORED_FILES
with their inode number as extension (ie, file.12345).
--restore-file 'path' Will restore file 'path'. 'path' is relative to root
of the partition and does not start with a '/' (it
must be one of the paths returned by --dump-names).
The restored file is created in the current
directory as 'RECOVERED_FILES/path'.
--restore-files 'path' Will restore files which are listed in the file 'path'.
Each filename should be in the same format as an option
to --restore-file, and there should be one per line.
--output-dir 'path' Restore files in the output dir 'path'.
By default the restored files are created under current directory 'RECOVERED_FILES'.
--restore-all Attempts to restore everything.
-j journal Reads an external journal from the named file.
-b blocknumber Uses the backup superblock at blocknumber when opening
the file system.
-B blocksize Uses blocksize as the block size when opening the file
system. The number should be the number of bytes.
extundelete Usage Example
Read the partition (/dev/sda1) and restore (–restore-file) the given file name (root/importantfile):
WARNING: Extended attributes are not restored.
WARNING: EXT3_FEATURE_INCOMPAT_RECOVER is set.
The partition should be unmounted to undelete any files without further data loss.
If the partition is not currently mounted, this message indicates
it was improperly unmounted, and you should run fsck before continuing.
If you decide to continue, extundelete may overwrite some of the deleted
files and make recovering those files impossible. You should unmount the
file system and check it with fsck before using extundelete.
