How is it even possible to accidentally format all disks including backups???

With decent recovery software, even the original filenames can usually be recovered.

As it is, filenames like Found_297934336_13592064 are pretty meaningless; there is no way of telling what kind of file they are (e.g. exe, dll, bin, txt, doc, docx, docm, dot, dotx, dotm, xls, xlsx, xlsm, ppt, pptx, pptm, psdt, ost, etc., etc.). Before you can do anything meaningful, you'll need some software to analyse each and every file to determine its type and apply the appropriate file extension. Only then might you be able to use Excel, PowerPoint, Word, etc. to do the kind of renaming you're after. Or you could try using recovery software better suited to the task.
