I accidentally delete the backing file. It was a very old 200GB file from 2018. The snapshot is 1 TB and I can't use it. My server is down. I tried to recover the file with all the tools I found (testdisk, photorec, rr-studios) with no luck. I just issue a qemu-img info on the snapshot and the error shows up, and I unmount the partition. Remount in ro and use the tools I mentioned.
Is there something I can do to recover the files in the snapshot? It is the /home directory from my server and I have customers waiting for email and stuff. I'll pay for the advice or the service Thanks in advance! Leonel
