restore VMware guest with GRT

Hello,

I understand if a VMware guest is restored using GRT from a tape drive. Backup Exec will restore first the vmdk file to a temporary directory on the media server and thereafter restore the files.

Does it mean if the VM guest has a 500GB vmdk the media server needs at least 500GB free space? I also guess the restore time will take some time.

I also understand that using a fixed disk as a backup location the vmdk file will be directly accessed and no temporary space is needed. It will also reduce the restore time drastically.

Is this right what I'm saying? We are using Backup Exec 2012 and I think even with BE 2014 nothing as change in terms of restore a vmdk with GRT.

Thanks,

Edy
