Recover (undelete) a file I have accidentally removed on my Linux server

Solution

The only recommended way to recover files that have been deleted, will be to
restore from your most recent backup.  Unfortunately, the default file system
for most new linux installs(ext3), does not lend itself to easily undeleting files.

This is what one of the developers of ext3, Andreas Dilger, said about it:

In order to ensure that ext3 can safely resume an unlink after a crash, it actually
zeros out the block pointers in the inode, whereas ext2 just marks these blocks as
unused in the block bitmaps and marks the inode as “deleted” and leaves the block
pointers alone.

Your only hope is to “grep” for parts of your files that have been deleted and hope
for the best.
