禁用备份后使用 powershell 脚本恢复 Azure VM 备份

Question

I would like to resume my backup after disabling backup. Used the below commands for disabling and enabling. Disabling backup : Disable-AzRecoveryServicesBackupProtection -Item $backupItems -Force Enabling backup : Enable-AzRecoveryServicesBackupProtection

Now if I run Enable-AzRecoveryServicesBackupProtection command then I am getting the error. My use case is I want to check RSV exist or not and if RSV is not exist then I should create new RSV,new policy,enable the policy and run the backup and disabling the backup using the above command. Now,if I run the same script again and since RSV is created already along with policy now and here I want to resume my backup only(When I first run my script I have disabled my backup).Only for that I am not able to find any powershell command.If I run the command Enable-AzRecoveryServicesBackupProtection then its failing with the below error.So please help me to understand how to handle this using powershell script. The entire steps have been done through powershell script.

Error:

##[error]Item is not protected. Please check if item is associated with any policy. ##[error]PowerShell exited with code '1'.

Also, my powershell script should handle the below scenario.

Requirement for Production env: My powershell script should only run the backup using already existing policy which might be different than the policy which I declared in powershell script and which have already backup running. So here I should only run backup in prod environment regardless of which policy its using.How to handle this scenario?
