Difficulty: HardRecovery Services Vaults and Backup Vaults

An administrator is designing a backup strategy for the following resources in an Azure environment:

Resource NameResource TypeRegionResource GroupSubscription
`vm-ops-prod`Virtual machineWest US`rg-west-ops``Subscription1`
`disk-ops-data`Managed diskWest US`rg-west-data``Subscription1`
`pg-orders-prod`Azure Database for PostgreSQLEast US`rg-east-db``Subscription2`
`share-logs-prod`Azure File shareEast US`rg-east-storage``Subscription2`

The environment currently contains two vaults:
* A Recovery Services vault named `rsv-west` located in `rg-west-ops` in the `West US` region of `Subscription1`
* A Backup vault named `bv-east` located in `rg-east-db` in the `East US` region of `Subscription2`

Which of the resources can be successfully backed up using only the existing vaults?

  1. A
    vm-ops-prod and share-logs-prod only
  2. B
    disk-ops-data and pg-orders-prod only
  3. vm-ops-prod and pg-orders-prod onlyAnswer
  4. D
    vm-ops-prod, disk-ops-data, and share-logs-prod only

Answer

Only vm-ops-prod and pg-orders-prod can be backed up using the existing vaults.
The correct answer is the option stating that only vm-ops-prod and pg-orders-prod can be backed up. This is because vm-ops-prod (Azure VM) is in West US and can be backed up to rsv-west (Recovery Services vault in West US). Similarly, pg-orders-prod (PostgreSQL) is in East US and can be backed up to bv-east (Backup vault in East US).

Step-by-Step Solution

1
Analyze the backup requirements for the virtual machine (vm-ops-prod) and the Recovery Services vault (rsv-west).
The virtual machine is in West US (Subscription1). Azure VM backup requires a Recovery Services vault in the same region and subscription. Since rsv-west is a Recovery Services vault in West US (Subscription1), vm-ops-prod can be successfully backed up to rsv-west.
Recovery Services vaults support Azure VM backups, and the vault must reside in the same region and subscription as the target virtual machine.
2
Analyze the backup requirements for the managed disk (disk-ops-data).
The managed disk is in West US (Subscription1). Azure Disk Backup requires a Backup vault in the same region and subscription. The only Backup vault available is bv-east (East US, Subscription2). The Recovery Services vault rsv-west is in the correct region but does not support Azure Disk backup.
Azure Disk backup is supported by Backup vaults (not Recovery Services vaults) and requires the vault to be in the exact same region and subscription as the disk.
3
Analyze the backup requirements for the Azure Database for PostgreSQL server (pg-orders-prod) and the Backup vault (bv-east).
The database is in East US (Subscription2). PostgreSQL backup requires a Backup vault in the same region and subscription. Since bv-east is a Backup vault in East US (Subscription2), pg-orders-prod can be successfully backed up to bv-east.
Backup vaults support Azure Database for PostgreSQL backups, and the vault must reside in the same region and subscription as the target database.
4
Analyze the backup requirements for the Azure File share (share-logs-prod).
The file share is in East US (Subscription2). Azure Files backup requires a Recovery Services vault in the same region and subscription. The only Recovery Services vault available is rsv-west (West US, Subscription1). The Backup vault bv-east is in the correct region and subscription but does not support Azure Files backup.
Azure Files backup is supported by Recovery Services vaults (not Backup vaults) and requires the vault to be in the same region and subscription as the storage account hosting the file share.

Key Concept

Azure Backup vault types (Recovery Services Vault vs. Backup Vault) have distinct resource support matrices and strict regional and subscription alignment constraints.
