General availability: Azure Backup supports backup of Write Accelerator enabled disks

Published date: May 24, 2022

Today, we are announcing the general availability of backup for Write Accelerator enabled disks. These disks are widely used by Azure customers with M-Series Virtual Machines (VMs) to improve the I/O latency of writes against Azure Premium Storage. Until now, as part of preview, Azure Backup has offered backup support for such disks to enrolled customers. With this general availability announcement, this support is available to all customers who configure Azure Virtual Machine Backup with disks enabled with Write Accelarator. You can choose to configure selective disk feature to remove the backup of these disks as part of Azure Virtual Machine Backup.

For more details, refer to our documentation.
