I cannot move storage account from one backup vault to another

Question

We have an existing Storage account backed up in a storage vault using LRS

We want to backup the storage account to a GRS vault but when backup instance does not present the storage account in the list of datasources

The old backup vault showed 2 entries for the storage accounts with two different storage resource groups.

(1) uroreportstorage under the testtier1 resource group

(2) uroreportstorage under the uroreport_production resource group

We would like to disconnect the uroreportstorage account From Blob-vault-Backup-001 To ProductionBackup.

Hi Richard Hart

Since you have already protected the storage account with the vault-LRS storage redundancy, and now you intend to have the backups with GRS redundancy with the new vault, you need to first unprotect the storage account with the existing vault, then only you can register/protect with the new vault-GRS redundancy. because a storage account can only be registered and protected by one backup vault at a time.

Steps to Unprotect/ disconnect the Storage Account from the Old Vault:

1)Stop Protection and Delete Backup Data

·       Go to the Old Backup Vault (Blob-vault-Backup-001).

·       Navigate to Backup Instances:

·       Find both entries for uroreportstorage under each resource group.

·       Stop Backup for Each Instance:

·       Select each backup instance.

·       Choose Stop Backup.

·       Select Delete Backup Data to ensure the storage account is fully released from the vault.

2)Unregister the Storage Account

·       After stopping protection and deleting backup data for all instances:

·       Go to the Backup Infrastructure section in the old vault.

·       Select Storage Accounts.

·       Find uroreportstorage and select Unregister.

3)Register and Protect the Storage Account in the New Vault

1)Assign Required Permissions

Ensure the new vault (ProductionBackup) has the Storage Account Backup Contributor role assigned on the storage account.

2)Configure Backup in the New Vault

·       Go to the Business Continuity Center or Backup Center.

·       Select + Configure protection.

·       Choose Azure Blobs (Azure Storage) as the datasource type.

·       Select the new vault (ProductionBackup).

·       The storage account should now appear in the list of available datasources.

·       Proceed to configure the backup policy and complete the setup.

Notes:

If the storage account still does not appear, ensure all backup data is deleted and the account is unregistered from all old vaults and resource groups.

If you have multiple subscriptions or cross-resource group scenarios, use the appropriate filters in the portal to locate the storage account
