Generally Available: Support for Cross Region Restore for PostgreSQL backups
发布日期：一月 31, 2024
Cross Region Restore of PostgreSQL backups using Azure Backup is now generally available. Azure Backup uses Read-Access Geo Redundant Storage (RA-GRS) that stores three replicas of backup data across each of the two paired regions. While Geo-Redundant Storage (GRS) allows you to access your secondary region backups when Azure declares a disaster, enabling Cross Region Restore allows you to access and do restore operation from the backups residing in the paired region at all the times, which includes non-outage scenarios.
Enable the Cross Region Restore option when:
- You need to do recovery drills on your secondary region backups to assess disaster readiness.
- You need high resiliency of backup data.
This capability helps you in the following scenarios:
- When the primary region is available to test data backed up in the secondary region for audit/compliance purposes.
- When the primary region is unavailable, you can trigger restore of backed-up data in the secondary region without any wait time even if the Azure primary region is partially or completely unavailable.
Currently, this feature is available for PostgreSQL backups in all public regions. With this, Azure Backup offers a compelling set of durability options for your backup data residing in Backup vaults, including Zonally-redundant Storage (ZRS) for intra-region high durability, Locally-redundant storage (LRS) for low-cost single region durability, and Geo-redundant storage (GRS) for high durability across regions when the primary region is unavailable. By enabling Cross Region Restore feature, you can also access the secondary region backup data from Azure Backup even without an outage.
