I allways say “an untested backup does not exist”
A backup that is untested is a backup that does not exist?
A backup that is untested does not exist?
There exists no backup that is untested?
Any interpretation of your statement seems cautionary to me. :-)
E: typo
I don’t understand what you are trying to say, my point is that until you have tested your backups you can’t rely on them, and thus should not bring them into consideration when planning disaster recovery procedures until you know they are good.
I am not refuting or opposing your statement. I understood your point very well, but the brevity of your statement led to more than one interpretation.
I am merely pointing out whichever way one interprets your statement, it serves as a good warning about keeping one’s backups tested.
