Cannot remove resource group

Question

During the attempt to delete a resource group, I have accounted the following error: Failed to delete resource group azure-storage-account-resource-group: Deletion of resource group 'azure-storage-account-resource-group' failed as resources with identifiers 'Microsoft.RecoveryServices/vaults/vault-lrywtw7h' could not be deleted. The provisioning state of the resource group will be rolled back. The tracking Id is '82d0d23b-2a8f-4f46-b353-693159f6b212'. Please check audit logs for more details.

Answer 1

From the Microsoft Learn page:
You can't delete a Recovery Services vault with any of the following dependencies:

• You can't delete a vault that contains protected data sources (for example, IaaS VMs, SQL databases, Azure file shares).
• You can't delete a vault that contains backup data. Once backup data is deleted, it will go into the soft deleted state.
• You can't delete a vault that contains backup data in the soft deleted state.
• You can't delete a vault that has registered storage accounts.

Please only delete the backups if you are 100% sure you don't need them anymore.
