Backing up Azure VM's with disks greater than 1TB
The standard VM backup can only backup VM's that have disks of size 1TB or less. Is there a workaround or alternative for this?
Hello Greg,
To upload your VHD file larger than 1TB from on-premises directly to Azure as a page blob or unmanaged disk, you can use the latest tool sets:
Azure tools Supported versions
| Azure PowerShell | Version number 4.1.0: June 2017 release or later |
| Azure CLI v1 | Version number 0.10.13: May 2017 release or later |
| AzCopy | Version number 6.1.0: June 2017 release or later |
The support for Azure CLI v2 and Azure Storage Explorer is coming soon. Also, Azure Site Recovery (ASR) now supports the disaster recovery and migration of on-premises virtual machines and physical servers with disk sizes of up to 4095 GB to Azure.
Before you start protecting virtual machines/physical servers with greater than 1 TB disks, you need to install the latest update on your existing on-premises ASR infrastructure. This is a mandatory step for existing ASR users.
Dave, thank you for your response.
My query was not referring to on-premise VM or disks. We have several VM's in the cloud with disks larger than 1TB and we can't use the standard backup tool to protect them.
Hi Greg,
Are you using Azure Recovery Service Vault for backup ?
Hi Kasun.
We would make use of Azure Recovery Service Vault for backup, but the limitation of 1TB disks prevents us from using it, unless there is a workaround?
