I call it “Cloud 3-2-1” backup. You really should replicate your backups to a separate commercial provider, or even a local replica (depends on context). Most often, it’s to protect yourself from yourself.
I’ve given up on trying to convince other people, though. Fortunately for me, unlike you, it’s not my bread and butter to do so.
When we migrated Netflix to AWS in 2009-2011 we setup a separate archive account on AWS for backups and also made an extra copy on GCP as our “off prem” equivalent. We also did a weekly restore from archive to refresh the test account data and make sure backups were working. I’ve documented that pattern many times, some people have even implemented it…
