Geo-backups and disaster recovery

Synapse performs a geo-backup once per day to a paired data center automatically, and that's why the option to enable a geo-backup policy for your dedicated SQL pool is disabled. The Recovery Point Objective (RPO) for a geo-backup is 24 hours. This geo-backup can be used to restore your SQL pool if the restore points in the primary region are not available.

In this section, we are going to create geo-redundant restore points using the Azure portal and PowerShell script as well. This PowerShell script can be used for any dedicated SQL pool just by providing correct values for the parameters in the script.

As shown in the following screenshot, we cannot create a geo-backup policy for a dedicated SQL pool because the SQL pool is automatically backed up to the region pair. You can read about region pairs at the following link—https://docs.microsoft.com/en-us/azure/best-practices-availability-paired-regions:
