Back up an Azure VM using Azure Backup via REST API
This article describes how to manage backups for an Azure VM using Azure Backup via REST API. Configure protection for the first time for a previously unprotected Azure VM, trigger an on-demand backup for a protected Azure VM and modify backup properties of a backed-up VM via REST API as explained here. To protect an Azure VM using the Azure portal, see this article.
Learn how to create vault and create policy REST API tutorials for creating new vaults and policies.
Let's assume you want to protect a VM testVM under a resource group testRG to a Recovery Services vault testVault, present within the resource group testVaultRG, with the default policy (named DefaultPolicy).
Configure backup for an unprotected Azure VM using REST API
Discover unprotected Azure VMs
First, the vault should be able to identify the Azure VM. This is triggered using the refresh operation. It's an asynchronous POST operation that makes sure the vault gets the latest list of all unprotected VM in the current subscription and 'caches' them. Once the VM is 'cached', Recovery services will be able to access the VM and protect it.
POST https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{vaultresourceGroupname}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/refreshContainers?api-version=2016-12-01
The POST URI has {subscriptionId}, {vaultName}, {vaultresourceGroupName}, {fabricName} parameters. The {fabricName} is "Azure". According to our example, {vaultName} is "testVault" and {vaultresourceGroupName} is "testVaultRG". As all the required parameters are given in the URI, there's no need for a separate request body.
POST https://management.chinacloudapi.cn/Subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testVaultRG/providers/Microsoft.RecoveryServices/vaults/testVault/backupFabrics/Azure/refreshContainers?api-version=2016-12-01
Responses to refresh operation
The 'refresh' operation is an asynchronous operation. It means this operation creates another operation that needs to be tracked separately.
It returns two responses: 202 (Accepted) when another operation is created, and 200 (OK) when that operation completes.
| Name | Type | Description |
|---|---|---|
| 204 No Content | OK with No content returned | |
| 202 Accepted | Accepted |
Example responses to refresh operation:
Once the POST request is submitted, a 202 (Accepted) response is returned.

Selecting the relevant Azure VM
You can confirm that "caching" is done by listing all protectable items under the subscription and locate the desired VM in the response. The response of this operation also gives you information on how Recovery Services identifies a VM. Once you're familiar with the pattern, you can skip this step and directly proceed to enabling protection.
This operation is a GET operation.
GET https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{vaultresourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupProtectableItems?api-version=2016-12-01&$filter=backupManagementType eq 'AzureIaasVM'
The GET URI has all the required parameters. No additional request body is needed.

Tip
The number of values in a GET response is limited to 200 for a 'page'. Use the 'nextLink' field to get the URL for next set of responses.
The response contains the list of all unprotected Azure VMs and each {value} contains all the information required by Azure Recovery Service to configure backup. To configure backup, note the {name} field and the {virtualMachineId} field in {properties} section. Construct two variables from these field values as mentioned below.
- containerName = "iaasvmcontainer;"+
{name} - protectedItemName = "vm;"+
{name} {virtualMachineId}is used later in the request body
In the example, the above values translate to:
- containerName = "iaasvmcontainer;iaasvmcontainerv2;testRG;testVM"
- protectedItemName = "vm;iaasvmcontainerv2;testRG;testVM"
Enable protection for the Azure VM
After the relevant VM is "cached" and "identified", select the policy to protect. To know more about existing policies in the vault, refer to list Policy API. Then select the relevant policy by referring to the policy name. To create policies, refer to create policy tutorial. "DefaultPolicy" is selected in the example below.
Enabling protection is an asynchronous PUT operation that creates a 'protected item'.
https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{vaultresourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}?api-version=2019-05-13
The {containerName} and {protectedItemName} are as constructed above. The {fabricName} is "Azure". For our example, this translates to:
PUT https://management.chinacloudapi.cn/Subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testVaultRG/providers/Microsoft.RecoveryServices/vaults/testVault/backupFabrics/Azure/protectionContainers/iaasvmcontainer;iaasvmcontainerv2;testRG;testVM/protectedItems/vm;iaasvmcontainerv2;testRG;testVM?api-version=2019-05-13
Create the request body
To create a protected item, following are the components of the request body.
| Name | Type | Description |
|---|---|---|
| properties | AzureIaaSVMProtectedItem | ProtectedItem Resource properties |
For the complete list of definitions of the request body and other details, refer to create protected item REST API document.
Example request body:
The following request body defines properties required to create a protected item.
{
"properties": {
"protectedItemType": "Microsoft.Compute/virtualMachines",
"sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",

}
}
The {sourceResourceId} is the {virtualMachineId} mentioned above from the response of list protectable items.

"policyName": "DefaultPolicy"
}
}
This confirms that protection is enabled for the VM and the first backup will be triggered according to the policy schedule.
Excluding disks in Azure VM backup
Azure Backup also provides a way to selectively back up a subset of disks in Azure VM. More details are provided here. If you want to selectively back up few disks during enabling protection, the following code snippet should be the request body during enabling protection.
{
"properties": {
"protectedItemType": "Microsoft.Compute/virtualMachines",
"sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
"policyId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testVaultRG/providers/microsoft.recoveryservices/vaults/testVault/backupPolicies/DefaultPolicy",
"extendedProperties": {
"diskExclusionProperties":{
"diskLunList":[0,1],
"isInclusionList":true
}
}
}
}
In the request body above, the list of disks to be backed up are provided in the extended properties section.
| Property | Value |
|---|---|
| diskLunList | The disk LUN list is a list of LUNs of data disks. OS disk is always backed up and doesn't need to be mentioned. |
| IsInclusionList | Should be true for the LUNs to be included during backup. If it's false, the aforementioned LUNs will be excluded. |
So, if the requirement is to back up only the OS disk, then all data disks should be excluded. An easier way is to say that no data disks should be included. So the disk LUN list will be empty and the IsInclusionList will be true. Similarly, think of what is the easier way of selecting a subset: A few disks should be always excluded or a few disks should always be included. Choose the LUN list and the boolean variable value accordingly.
Trigger an on-demand backup for a protected Azure VM
Once an Azure VM is configured for backup, backups happen according to the policy schedule. You can wait for the first scheduled backup or trigger an on-demand backup anytime. Retention for on-demand backups is separate from backup policy's retention and can be specified to a particular date-time. If not specified, it's assumed to be 30 days from the day of the trigger of on-demand backup.
Triggering an on-demand backup is a POST operation.
POST https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/backup?api-version=2016-12-01
The {containerName} and {protectedItemName} are as constructed above. The {fabricName} is "Azure". For our example, this translates to:
POST https://management.chinacloudapi.cn/Subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testVaultRG/providers/Microsoft.RecoveryServices/vaults/testVault/backupFabrics/Azure/protectionContainers/iaasvmcontainer;iaasvmcontainerv2;testRG;testVM/protectedItems/vm;iaasvmcontainerv2;testRG;testVM/backup?api-version=2016-12-01
Create the request body for on-demand backup
To trigger an on-demand backup, following are the components of the request body.
| Name | Type | Description |
|---|---|---|
| properties | IaaSVMBackupRequest | BackupRequestResource properties |
For the complete list of definitions of the request body and other details, refer to trigger backups for protected items REST API document.
Example request body for on-demand backup
The following request body defines properties required to trigger a backup for a protected item. If the retention isn't specified, it will be retained for 30 days from the time of trigger of the backup job.

Since the backup job is a long running operation, it needs to be tracked as explained in the monitor jobs using REST API document.
Modify the backup configuration for a protected Azure VM
Changing the policy of protection
To change the policy with which VM is protected, you can use the same format as enabling protection). Just provide the new policy ID in the request body and submit the request. For example: To change the policy of testVM from 'DefaultPolicy' to 'ProdPolicy', provide the 'ProdPolicy' ID in the request body.
{
"properties": {
"protectedItemType": "Microsoft.Compute/virtualMachines",
"sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
"policyId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testVaultRG/providers/microsoft.recoveryservices/vaults/testVault/backupPolicies/ProdPolicy"
}
}
The response will follow the same format as mentioned for enabling protection
Excluding disks during Azure VM protection
If the Azure VM is already backed up, you can specify the list of disks to be backed up or excluded by changing the policy of protection. Just prepare the request in the same format as excluding disks during enabling protection
Important
The request body above is always the final copy of data disks to be excluded or included. This doesn't add to the previous configuration. For example: If you first update the protection as "exclude data disk 1" and then repeat with "exclude data disk 2", only data disk 2 is excluded in the subsequent backups and data disk 1 will be included. This is always the final list which will be included/excluded in the subsequent backups.
To get the current list of disks which are excluded or included, get the protected item information as mentioned here. The response will provide the list of data disk LUNs and indicates whether they're included or excluded.
Stop protection but retain existing data
To remove protection on a protected VM but retain the data already backed up, remove the policy in the request body and submit the request. Once the association with policy is removed, backups are no longer triggered and no new recovery points are created.
{
"properties": {
"protectedItemType": "Microsoft.Compute/virtualMachines",
"sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
"policyId": ""
}
}
The response will follow the same format as mentioned for triggering an on-demand backup. The resultant job should be tracked as explained in the monitor jobs using REST API document.
Stop protection and delete data
To remove the protection on a protected VM and delete the backup data as well, perform a delete operation as detailed here.
Stopping protection and deleting data is a DELETE operation.
DELETE https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}?api-version=2019-05-13
The {containerName} and {protectedItemName} are as constructed above. {fabricName} is "Azure". For our example, this translates to:
DELETE https://management.chinacloudapi.cn//Subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testVaultRG/providers/Microsoft.RecoveryServices/vaults/testVault/backupFabrics/Azure/protectionContainers/iaasvmcontainer;iaasvmcontainerv2;testRG;testVM/protectedItems/vm;iaasvmcontainerv2;testRG;testVM?api-version=2019-05-13
Responses for delete protection
DELETE protection is an asynchronous operation. It means this operation creates another operation that needs to be tracked separately.
It returns two responses: 202 (Accepted) when another operation is created, and 204 (NoContent) when that operation completes.
| Name | Type | Description |
|---|---|---|
| 204 NoContent | NoContent | |
| 202 Accepted | Accepted |
Important
In order to protect against accidental delete scenarios, there's a soft-delete feature available for Recovery Services vault. If the soft-delete state of the vault is set to enabled, then the delete operation won't immediately delete the data. It will be kept for 14 days and then permanently purged. You aren't charged for storage for this 14 days period. To undo the deletion operation, refer to the undo-delete section.
Undo the deletion
Undoing the accidental deletion is similar to creating the backup item. After you undo the deletion, the item is retained but no future backups are triggered.
Undo deletion is a PUT operation which is very similar to changing the policy and/or enabling the protection. Just provide the intent to undo the deletion with the variable isRehydrate in the request body and submit the request. For example: To undo the deletion for testVM, the following request body should be used.
{
"properties": {
"protectedItemType": "Microsoft.Compute/virtualMachines",
"protectionState": "ProtectionStopped",
"sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
"isRehydrate": true
}
}
The response will follow the same format as mentioned for triggering an on-demand backup. The resultant job should be tracked as explained in the monitor jobs using REST API document.
