Azure Backup Policy VM Limit / Recommendation

Question

Hello together,

yesterday I saw that there is a limit on assigning VMs to an Azure Backup Policy.

The official Microsoft documentation says: Yes, there's a limit of 100 VMs that can be associated to the same backup policy from the portal. We recommend that for more than 100 VMs, create multiple backup policies with same schedule or different schedule. (https://learn.microsoft.com/en-us/azure/backup/backup-azure-vm-backup-faq#is-there-a-limit-on-number-of-vms-that-can-beassociated-with-the-same-backup-policy).

The confusing thing is, that a customer of mine is already using almost 200 VMs which are backed up with one policy. And in the portal I am still able to add more VMs.
But if I try to add a new VM with PowerShell, I get an error: Cannot configure backup for more than 100 VMs per policy.

So my question is: Is this just a recommendation or really a hard limit?
And what do you recommend?

Best regards
Christoph

Answer 1

Hello Christoph,

Number of VMs supported to Azure Backup Policy through PowerShell has a hard limit set now which is 100. This is a recent change introduced. At the same time, you may add more than 100 from portal.

@ChristophDambacher-4896 : The Powershell and CLI clients haven't been updated with the latest limit. The product team will update them in the releases in July. Hope this helps.
