1. Log in to the Azure portal (https://portal.azure.com/).
2. In the left-hand menu, click on “Recovery Services vaults”.
3. Select the recovery services vault that you want to remediate.
4. Click on the “Backup policy” option in the left-hand menu.
5. In the “Backup policy” page, click on the “Edit” button.
6. In the “Backup policy” editor, click on the “Retention” tab.
7. In the “Retention” tab, set the retention period to the desired value.
8. Click on the “Save” button to save the changes.

​

1. Open the Azure CLI in your terminal or command prompt.
2. Run the following command to check the current retention period for backups: az backup policy show --name <backup-policy-name> --resource-group <resource-group-name> --vault-name <vault-name> Replace <backup-policy-name>, <resource-group-name> and <vault-name> with the actual names of your backup policy, resource group and vault respectively.
3. Check the retentionPolicy object in the output to see the current retention period.
4. Run the following command to update the retention period to the desired value: az backup policy set --name <backup-policy-name> --resource-group <resource-group-name> --vault-name <vault-name> --retention-days <number-of-days> Replace <backup-policy-name>, <resource-group-name>, <vault-name> and <number-of-days> with the actual names of your backup policy, resource group, vault and the desired number of retention days respectively.
5. Verify that the retention period has been updated by running the command in step 2 again and checking the retentionPolicy object in the output.
6. Repeat steps 2-5 for all backup policies in your Azure environment to ensure that all backups have sufficient retention periods.

1. Import the required libraries for Azure authentication and management:

from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.recoveryservicesbackup import RecoveryServicesBackupClient
from azure.mgmt.recoveryservicesbackup.models import ProtectionPolicyResource

2. Authenticate with Azure using Service Principal credentials:

credentials = ServicePrincipalCredentials(
    client_id='<client-id>',
    secret='<client-secret>',
    tenant='<tenant-id>'
)

3. Instantiate a RecoveryServicesBackupClient object using the credentials:

client = RecoveryServicesBackupClient(credentials, '<subscription-id>')

4. Get the list of backup protection policies:

policies = client.protection_policies.list('<resource-group-name>', '<vault-name>')

5. For each policy, check if the retention period is sufficient:

for policy in policies:
    if policy.backup_management_type == 'AzureIaasVM':
        if policy.recovery_points_retention_period == 30:
            policy.recovery_points_retention_period = 60
            client.protection_policies.create_or_update('<resource-group-name>', '<vault-name>', policy.name, policy)

6. If the retention period is not sufficient (in this case, 30 days), update the policy with a new retention period (in this case, 60 days):

policy.recovery_points_retention_period = 60
client.protection_policies.create_or_update('<resource-group-name>', '<vault-name>', policy.name, policy)

7. Save the updated policy:

client.protection_policies.create_or_update('<resource-group-name>', '<vault-name>', policy.name, policy)

resource "azurerm_app_service" "APP_SERVICE" {
  name                = "APP_SERVICE_NAME"
  resource_group_name = azurerm_resource_group.RG.name
  location            = azurerm_resource_group.RG.location
  app_service_plan_id = azurerm_app_service_plan.PLAN.id

  site_config {}
}

# Configure backups with a sufficient retention period (substitute values as needed)
resource "azurerm_app_service_backup" "APP_SERVICE_BACKUP" {
  name                = "APP_SERVICE_BACKUP_NAME"
  resource_group_name = azurerm_resource_group.RG.name
  app_service_name    = azurerm_app_service.APP_SERVICE.name

  storage_account_url = "SAS_OR_BLOB_URL_FOR_BACKUPS" # replace with a valid SAS URL or blob URL

  schedule {
    frequency_interval     = 1              # every 1 day (example)
    frequency_unit         = "Day"          # "Day", "Hour"
    retention_period_in_days = 30           # set to the required minimum retention period
    keep_at_least_one_backup = true
  }
}

• APP_SERVICE_NAME with your App Service name.
• APP_SERVICE_BACKUP_NAME with a backup configuration name.
• SAS_OR_BLOB_URL_FOR_BACKUPS with a valid SAS URL or blob URL to your backup Storage Account container.
• RG and PLAN with your actual resource names/IDs.
