About a month ago, was having a conversation with a Pure Storage customer’s SQL Server backups. They were using Ola Hallengren’s scripts but mentioned something about writing the backups to multiple locations at once. I presumed they were executing the backup operation as normal, then using another script of some sort to then copy the backup files elsewhere. That’s when I learned that Ola has a parameter called MirrorDirectory, that exposes the MIRROR TO option in a native BACKUP command.
Click through to learn more about this command and the implications. I’d say that this sounds neat but also isn’t something I’d probably recommend.
