ext4magic : Linux admin tool, can help to recover deleted or overwritten files on ext3 and ext4 filesystems
I accidentally deleted a very important directory and the last backup was around one month old. Ironically because I wanted to do a new backup and cleaned up my home directory before. A lot of files and directories were moved and deleted until I realized my mistake. I tried other tools like extundelete without success. Then I found ext4magic and it was able to restore my directory completely without any data loss -- and that extremely fast. It saved my day, thank you very much!
