Backup and Recovery, Managed Instances

Disclaimer: I love Azure SQL Managed Instances (MIs) so far. They’re really cool, and I’m having a fun time playing with them. I’m about to describe a bug, and I’m sure this bug will be fixed soon, so it shouldn’t stop you from previewing Managed Instances. This post is not “MIs are t3h suxxors” –…

Managed Instances, Replication
