One Backup to 2 Different Drives

Running Ghost 15 SP1 on Vista Home 32-bit

 

Here's what I am attempting to do with no success.

 

I want to do 2 full backups of my computer daily, to 2 different external usb drives.

BU1 is no problem.  I set it to run with the destination set to drive F with the alias of BU1 and a new recovery point set on the first of each month.

 

When I try to set up the second backup (BU2) with a destination of G (alias BU2) I am unable to use the recovery point option, only the independent recovery point option is available.  The independent recovery point is massive.

 

When I came up against that limitation I attempted to fool Ghost into thinking that both of the drives are the same backup destination by setting each of the external drives to the same letter and the same volume label.  Ghost still sees them by their original aliases, even after reformatting them.

 

I use this for my business and my goal is to manually run an incremental (recovery point set) backup at the end of the day and take that drive home with me, then plug in the second drive and run a scheduled, recovery point set backup to a different drive, overnight.

 

By the way, the reason I am trying to do a full backup of my drive twice, instead of just backing up the files that I need is that when I try to just do those I get a snapshot error message.

 

Does any body have any ideas?

 

TIA
