Contact PSA for Availability-Pricing / FAST-PASS 7 Azure Backup Storage-Backup Storage is an auto-scaling, reliable set of storage accounts managed by Azure Backup and isolated from customer tenants to provide additional security. Azure Backup uses Blob storage for storing your backups. Charges for storage are separate from the cost of Azure Backup Protected Instances. By default, all backup data protected by Azure Backup go into the Standard tier. For backups with long term retention (monthly and yearly backups with retention longer than 6 months), you have the option to move them to the Archive tier. In Standard tier, you have the flexibility to choose between locally redundant storage (LRS), zone redundant storage (ZRS) or geo-redundant storage (GRS) for your backups. If you enable cross-region-restore, we upgrade your backup storage from GRS to read-access geo-redundant storage (RA-GRS).
