Feature req: Restore virtual disk to new disk without power off

Post by Unreliably-Recurring » Aug 22, 2019 11:04 pm

https://helpcenter.veeam.com/docs/backu ... l?ver=95u4 says that B&R will power off the vm whether restoring over a virtual disk, or restoring it to a new virtual disk on a vm.

Restoring a large virtual disk can take hours.
Has there been consideration to not require this when restoring a backup to a new virtual disk for the vm?

Using vSphere to add a virtual disk to a vm doesn't require that the vm be shut down- the vm's OS can subsequently be told to discover it.

Hello!

This idea is really interesting but you cannot get write access to a virtual disk that is in active use. This is the limitation of VADP (VMware vStorage APIs for Data Protection).
External write access is not required when you add a disk to a vm using vSphere client, a disk is discovered by OS itself.

On the other hand you can select some "dummy" vm as a restore target (just click Browse and select some VM from the virtual environment) and once restore is completed you can attach restored disk to a necessary vm. What do you think about it?

Thanks!

v10 will support instant recovery of individual disks, so this should hopefully solve the issue.

Yup- that's what I ended up doing when I discovered the power-off requirement.

Thank you, Gostev, for the info, too.
