I'm curious about the strategies people use for backing up critical data and infrastructure. I know that regional disasters are uncommon, perhaps happening once every decade, but do you still opt for Geo-Redundant Storage (GRS) backups for vital data? Or do you go for Locally-Redundant Storage (LRS) or Zone-Redundant Storage (ZRS) since these events are so rare? I realize factors like company size, space, revenue, and risk tolerance play a role in these decisions.

For our regular operations, we stick with LRS or ZRS. However, when it comes to our critical data, GRS is our go-to. Even though regional disasters are infrequent, the thought of losing important data is too risky for us. It costs a bit more, but the peace of mind it provides is totally worth it.
How do you handle backups for non-user data? Was it all deployed using Infrastructure as Code?
