e2undo
E2undo is a command-line tool used in Linux systems. It is specifically designed to recover files from an ext2/3/4 file system. The tool operates by undoing the effects of the 'rm' command, allowing users to recover their deleted files. E2undo is compatible with most modern file systems, making it a versatile tool for file recovery. One of its key features is the ability to restore files, even if they were deleted a long time ago. The tool works by analyzing the journaling system of the file system and reconstructing the deleted files from its metadata. E2undo can be used on live systems or on unmounted file systems, reducing downtime and inconvenience for users. It supports both interactive and automated modes of operation, catering to different user preferences. The tool is highly reliable and has gained a reputation for successfully recovering deleted files, even in complex scenarios. Before using E2undo, it is advisable to create a backup of the affected file system to avoid any potential data loss during the recovery process.
