A simple way of doing it, is to just move some of the data somewhere else, and then restore that backup. If the contents are fine, then all is well, and if they aren’t, then you can delete the broken restore, and move the files back where they were. Depending on how you are doing backups, some system have built in “dry-run” style tests were they can test themselves, but you should still verify the contents every so often.
How should I go about verifying or rehearsing data restoration when my main computer is fine and don’t have a spare to test with?
Restore file -> md5sum against original -> delete -> repeat with another file.
Script it up!
