Linux recovery of deleted files
Restoring deleted files on Linux can be quite a difficult task, but in most cases it is possible to return lost data. Here are some ways that can help you cope with this problem:
1. Using the "undelete" command: Some Linux distributions provide the "undelete" utility, which allows you to restore deleted files from the recycle bin or other system directories.
2. Using programs for data recovery: There are a number of third-party programs for Linux, such as TestDisk and PhotoRec, which specialize in detecting and restoring deleted files of various types (JPEG/MP3/DOC/XLS/PDF format files, etc.).
3. Checking backup copies: If you made regular backup copies of your system or a specific directory before deleting the file(s), then check these backup archives - they may contain the necessary information.
4. Examine the hard disk: Search for fragmented parts of your hard disk using the Foremost or Scalpel tool. These programs can help restore deleted files, even if they have been overwritten.
5. Turn to specialists: If you are not confident in your skills or the problem is very complicated, it is better to seek help from a data recovery professional. They have certain tools and knowledge to solve such problems.
In any case, in the case of lost files, it is very important to stop using this partition/disk as soon as possible before starting the procedures for its possible restoration - this will avoid deeper damage to the information on the hard disk and increase the chances of a successful outcome.
