Backup to Disk Troubles

I'm embarrassed to even have to ask this, but apparently my search-fu is weak.  I'm having trouble finding where to even read what I'm doing wrong.

I have a 1.8TB disk that I want to use strictly for disk-disk backup.  I created a B2D folder in Symantec Backup Exec 2010 that is 1.5TB, allocated maximum size.  I start a backup and it kicks off fine, but notifies me of space shortage much sooner than I would expect.  Upon further investigation, it appears to happen after about 300GB of backup.  I looked at the disk directly, and there is a 1.5TB .cfg file (as I would expect), but there are file folders labeled IMG******* that appear to have other backup info in it.  I was expecting all the data backed up to the disk to be saved inside the large .cfg files, but the data being saved outside it is causing the space on the disk to run out.

If it matters, the backup is of multiple virtual machines using the VMware agent.  I am backing up machines with both a remote agent for windows installed on the guest, and some without.

It seems I should be able to back up less than 1TB with no problem when I have a 1.8TB drive, but I am clearly doing something wrong.  Can someone point me in the right direction?  Thanks!!

You've enabled Granular Restore Technology (GRT) for the VMware agent to allow you to restore individual file from VM backups. GRT technology always uses IMGxxxxx folders to store the backups. That's why you see those folders.

From your description it looks like you specified "Maximum size" as 1.5Tb and checked the "Allocate disk space" checkbox. I suggest you change that. Delete your B2D folder and recreate it. Specifiy "Maximum size" to something more like 5GB.
Or you could continue as we've been doing, but in that case you have to disable GRT from all of you VMware, Exchange, Sharepoint or Active Directory backup jobs to avoid from creating IMG folders.
