When backing up a FreeBSD on a virtual machine on ESXi:
It took about 5 hours to finish with Exceptions:
Media Label: IMG000001
GRT backup set folder: E:\BEData\IMG000001
Transport mode 'nbd' was used for the disk 'WebProxy.vmdk'
Transport mode 'nbd' was used for the disk 'WebProxy_1.vmdk'
V-79-57344-38761 - Failed to mount one or more virtual disk images because they contained GPT style disks. Backups that were enabled for Granular Recovery Technology may not be available for restore.
In the backup job deselect the option "Use Backup Exec Granular Recovery Technology (GRT) to enable the restore of individual files and folders from virtual machines" under Settings-VMware Virtual Infrastructure.
To simulate a virtual machine is gone completely, I build a fresh install virtual machine with Windows 7 and try to restore the system from the backup:
It took about 10 minutes to restore from the backup. However, the system could not be booted up and it shows the Blue Screen of Death. The solution and the proper procedure is to use a backup exec recovery disk (a .ISO image) to boot up the machine then restore from the Backup Exec server.
