I doubt I need to tell you that a backup is one of the most important things you can have to reduce the impact of certain types of system outages or cybersecurity attacks.
Without a backup, you are at risk of losing data.
A backup is only a backup if you have tested that you can restore from it.
Otherwise, it might be as useful as a chocolate teapot:
Beautiful to look at when you don’t need it, but guaranteed to fail when you do.
So what do you do?
Make sure that someone is responsible for testing your backups on a frequent basis.
And make sure they are providing you with evidence that these tests are succeeding.
An absence of evidence may be evidence of absence.
