How to take ultradisk backup

Question

Azure Ultra Disks do not support available default az tools .Is there any alternative ways to take backup

Answer 1

@monalipatil-7473 Thank you for reaching out to Microsoft Q&A. I understand that you are want to take a backup of your ultradisk.

As seen from the limitations section of Selective disk backup, currently, Azure VM backup doesn't support VMs with ultra-disks or shared disks attached to them. Selective disk backup can't be used to in such cases, which exclude the disk and backup the VM.

An alternate solution would be adding additional data disks (managed). Use multiple disk and stripe them together to mitigate the overall per disk IO requirement.

As SaiKishor, commented - striped Premium Disks will work.

The current restriction is due to snapshot backups at the hypervisor - however, you can use an Agent based Backup to back up the Files and Folders and system state ONLY in the Virtual Machine.

Installing the Azure Backup Windows Agent (usually used for on-premises servers to backup to Azure) should work, as its an agent based backup that reads the files/folders within OS - https://learn.microsoft.com/en-us/azure/backup/backup-windows-with-mars-agent?WT.mc_id=AZ-MVP-5004796

The Veeam Agent for Windows Server will also work: https://www.veeam.com/windows-cloud-server-backup-agent.html
