Geo-restoring databases
A geo-restore allows you to restore a database from a geo-redundant backup to any available Azure SQL servers and SQL Managed Instance, irrespective of the region.
The automatic backups of Azure SQL Database and SQL Managed Instance are geo-redundant by default, and are copied to a paired Azure region as and when they are taken. There is a maximum delay of one hour when copying a database to a paired geographical location. Therefore, in the case of a disaster, there can be up to an hour of data loss:

Geo-restore can be used to recover a database if an entire region is unavailable because of a disaster:

The most recent full and differential backups are used to perform a geo-restore.
Geo-restore doesn't support PITR. It is the most basic disaster...
