I was participating in a discussion forum on cybersecurity and critical data protection. One of the points that were brought up during the discussion was on the security of backups and whether these backups could themselves be subject to a cyberattack and I’m really interested in getting more insight on the subject.

How can someone ensure the sanity of their backups? How can they make sure they haven’t backed up a malware along with their data? Are there any tips or best practices for backup procedures?
