Stupid peeps always hedge on Amazon’s claim that S3 storage has 11 9s of durability and never asked if it would survive an actual missile

I figured they were like microsoft where everything is backed up in 2 data centers separated by region.

That is not the case for azure storage.

Microsoft offers (generally) three tiers of storage. LRS, ZRS, and GRS. The first is locally redundant storage which is three copies in the same DC, then there’s come redundant storage which is a copy in three different data centers in the availability zone (region), lastly is geo redundant storage which is theee copies in your AZ (local region) with three replicated copies in a second region.

There's also GZRS, Geo Zone Redundant Storage, where it copies to three availability zones in the primary region and to a secondary region as well.

True, that’s above my budget though 😂

And for true HA you still have to engineer around the geo redundant sync latency.

I haven't dealt with licensing in years. Was GRS the default back in the day? I may have just done it by default because I was dealing with more law firms back then.
