Linux tips & tricks -- 5 tools for data rescue
Linux tips & tricks -- 5 tools for data rescue
One of the most powerful IT tools I carry with me is a multi-boot USB stick with multiple Linux distributions and other tools on it. It can be an absolute lifesaver for emergency diagnostics, repair, and recovery.
Of these tools I've used ddrescue and photorec many times with impressive results.
One other thing you should carry in your IT toolbag, a reasonably large blank external USB (pref 3.0 these days) hard drive. Why? To recover data to, and to work on. There are many circumstances where recovering and repairing data in place is a bad idea, for example on a failing hard drive. In this case you use ddrescue to pull an image of the failing drive into an image file on the external drive (make sure is is formatted with a file system that can handle LARGE files. IE not FAT32) and then you perform your recovery operation on the image file instead of the original drive. There may even be circumstances where having a second USB drive to recover to is necessary. In other words a well stocked IT dept probably contains several multi-TB external USB drives and a few USB sticks with multi-boot tools.

I've posted on screen before. Here it is again because more examples are always a good thing.
