Backing up VM with deduped volumes

[MrJH]

Hello, we are currently running B&R 9.5 Free Edition on a dedicated server.

One of our Hyper-V VMs is running Windows Server 2012, with deduplication enabled on two of its VHDX drives. If we decide to backup the VM with Veeam, will there be any issues when restoring the VM? The VM will be backed up to an external USB 3.0 drive.

Many thanks.

Hi,

If you are asking if the data on the VM disks will inflate during the backup then the answer is no, it won't.

Thanks

Thank you for the reply.

What about the restore? Will dedupe metadata be preserved?

[PTide]

Since the deduplication occurs on the GuestOS level, yes, the dedupe meta will be preserved in case you perform volume level restore (be it entire machine or a separate vhdx). However if you go with FLR then the data of the files that you restore will be inflated.

Thanks

Ah that's great. Thanks for the help.
