Vista - Vista Backups

Hello. Looking for a little help. I am an MCSE, and pretty experienced with
servers and PCs. But I am a little confused here.

- I have a PC running Visa Business.

- It has two separate physical hard disk drives.

- The purpose of the second drive is to store regular backup images of the
first drive.

- In the Backup and Restore Center, I have chosen the option for Create
Backup Copies of Your Files and Folders, and scheduled it to run weekly on
Sundays at 7PM, and to store the files on the d-drive.

- This seems to be working well. But my d-drive is now almost full. If I
choose the Restore Files->Advanced option, there seems to be backups store
for the past several months - since I got the PC.

I would like to configure the backups to only keep the last 4 backups, or
the last 10GB of backups. But I don't see any place in the Backup and
Restore Center where I can configure any limits of retaining backups.

Any help you can provide would be appreciated. Thanks in advance.
