A small business uses Azure Backup to protect a critical file share hosted on an Azure Files storage account. They want to ensure that if the storage account is accidentally deleted, they can still recover the file share data. Which feature of Azure Backup for Azure Files provides this protection against accidental deletion of the source storage account?
- ARetention Lock
- BCross-Region Restore
- CSeparate Recovery Services vault
- DSoft Delete for Azure Files
Show answer & explanationAnswer & explanation
Correct answer: C. Separate Recovery Services vault
When you back up an Azure file share, the recovery points are stored in a Recovery Services vault. If the source storage account is accidentally deleted, the backup data in the separate Recovery Services vault remains intact and can be used to restore the file share to a new (or existing) storage account.
Why the other options are wrong
- A. Retention Lock prevents backup recovery points from being deleted or modified for a specified period, but doesn't prevent the source storage account from being deleted.
- B. Cross-Region Restore allows restoring data to a different region, but doesn't inherently protect against source storage account deletion if the vault is linked.
- D. Soft Delete for Azure Files protects individual files/shares from accidental deletion, not the entire storage account itself from being deleted.
Azure Backup Vault Isolation
Azure Backup stores recovery points in a Recovery Services vault, isolating them from the source data, thus protecting against accidental deletion of the source resource.
- Recovery Services vaults are independent resources.
- Backup data persists even if the original resource is deleted.
- Crucial for protecting against catastrophic data loss due to source deletion.
Memory trick: Vaults guard backups, even if the source gets zapped.
