Many years ago I worked for a company that had a tape backup system they sold with their computers. Due to a firmware screw up for fewmonths the backuptapes were written blank and thenwhen they were verified they verified as good. Fortunatelynone of the banks that were using the systems had a problem in that few months. In this case Schrödinger's backup was dead,alive and invisible. Regular testing is important.

If you don't test, you will have a Schrödinger's backup: both valid and invalid at the same time, until you try a restore.

With the discussion about backups, I would like to raise a question I have had for some time.
Having backups does no good if you cannot restore them. Files are rather easy to test.
But how do you test restoring a database?
I back it up with the usual tool. I have the docs to do the restore.
But how to test to make sure that restoring works, without clobbering the active database?
Thank you
you can recover on a different machine or start a second instance of the database on different ports. This is the kind of place where virtualization or containerization comes in handy.
Testing your backups is always a good idea.
