Who

You aren’t sure whether you should be doing backups?

You should.

A computer is the metal/plastic device itself PLUS the data recorded on the hard drives.

If you are responsible for a computer then you are responsible for both the box AND the data content.

If you think that you aren’t responsible, then I challenge you, right now, to reformat the hard drive, as if you’ve just had the computer stolen, and sit back and wait for the recovery process to start.
