The rm command can be a powerful tool for deleting data — until you delete the wrong files or directories. Thankfully, the ext3undel utility can recover accidently removed data on ext3 filesystems. Users can recover a specific file by name, or they can restore all files marked as deleted (though the filenames won’t be recovers, so they will have to look at the contents of the files to identify them).
Files on the ext3 filesystem have two parts. The file’s metadata — that is, the file name, size, and creation and access dates — is stored in a Unix data structure called an inode. The actual file data is stored in blocks on the hard drive. Deleting a file destroys the link between the metadata and the filesystem blocks, eliminating the association between the file’s information and content. Both the inodes and the data blocks are marked as free, and the operating system will use them to write new data when it needs to. But because the inodes and blocks are merely marked free and aren’t overwritten, users can rescue data as long as new data hasn’t been written there. That’s why it is important to recover data to a new partition: any changes to the filesystem risk overwriting data users wish to recover. Until then, an application can “save” deleted data by marking the blocks as in use, and reconnecting the inodes and the blocks symbolically. Continue reading
