I have finished an SBS 2008 VM and Server 2008 R2 VM for a BES. The VHD for the SBS2008 VM is a static 600GB VHD. This takes seven hours to backup up using Backup Exec 2010 R2, a Hyper-V license and external USB trives.
I am planning a larger projec this fall which will have an SBS 2011 VM and a SQL Server 2008 VM. I am concerned there will not be enought time in the middle of the night to back up the to VMs using external drives.
If I was to go to LTO-3 drives and a SCSI/SATA controller would the tape be faster than the USB drives?
