To geo-restore a single database from the Azure portal inside the region and server of the alternative, adhere to these methods:
Instance recovery restores a database to its transaction-consistent point out just ahead of instance failure.

The next sections give a conceptual overview of the different types of backups that may be manufactured as well as their usefulness in numerous recovery techniques.
Restoring from geo-redundant backups could perhaps lead to data loss in sure situations since Azure Geo-Redundant Storage (GRS) replicates data asynchronously to some secondary location. There may be some latency associated with the replication procedure, but the precise latency can differ determined by a number of things, such as the distance between the key and secondary areas and the current community situations.
