RTO for cross region restore of sql on VM

Assaf L 261 Reputation points

Based on this article there is an RPO definition for using cross region restore for a sql database on VM

I couldn't find what is the RTO for this type of ability?

Is it documented somewhere?

SQL Server on Azure Virtual Machines

    @Assaf L The Recovery Point Objective (RPO) for the backup data to be available in the secondary region is 12 hours. When you turn on Cross Region Restore (CRR), the RPO for the secondary region is 12 hours + log frequency duration (that can be set to a minimum of 15 minutes). You can find more information about Cross Region Restore in the article "Restore SQL Server databases on an Azure VM"


    Is cross region restore similar as the always on availability group failover?Cross region restore is just for backups.

    So essentially now there is a guaranteed 24hr RPO to have the data in the other region. At that point the customer can restore the data whenever needed.

    There is really no RTO as this is about restoring backup data, not doing a failover.

    SQL AG is a DR solution. It keeps multiple copies of the same data available on different SQL servers in case one goes down. If that is what you are needing, then you want to look at ASR and for it the RPO and RTO can be modified to fit as per your requirement. (adjusting recovery point increments etc).
