Public Preview: Azure Backup now supports Cross Region Restore for PostgreSQL backups
Datum publikování: 14 srpna, 2023
Cross Region Restore of PostgreSQL backups for Azure Backup customers is now in public preview. Azure Backup leverages Read-Access Geo Redundant Storage (RA-GRS) which stores 3 replicas of backup data across each of two paired regions. While leveraging Geo-Redundant Storage (GRS) allows you to access your secondary region backups when Azure declares a disaster, enabling Cross Region Restore enables you to access and perform restores from the backups residing in the paired region at all times which includes non-outage scenarios.
You should consider enabling Cross Region Restore option when:
1. You need to perform recovery drills on your secondary region backups to assess disaster readiness.
2. You need high resiliency of backup data.
The feature is currently available for PostgreSQL backups in select 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 region when primary region is unavailable by opting in for Cross Region Restore feature, you can also access the secondary region backup data from Azure Backup.
