Co-locating backup data on a single tape in DPM 2007
If you need to optimally use your backup tapes by storing multiple backups on the same tape, you need to turn on the Media Co-location feature in Microsoft System Center Data Protection Manager 2007. By default, DPM 2007 uses a single tape for each backup operation and does not use that tape again till it is expired, marked as free or erased.
In order to enable Media Co-location, you need to install the DPM 2007 Feature pack and then issue the following command in the DPM Shell:
Set-DPMGlobalProperty -DpmServer <DPM Server Name> -OptimizeTapeUsage $true
Please note that this command will not work unless you have the DPM 2007 Feature Pack installed. To verify that co-location was indeed enabled, check the Management > Libraries tab.
An important point to note is that, even with co-location enabled, DPM will not store two different backups from the same protection group into a single tape. The co-location feature only allows co-locating data from multiple protection groups with the same retention ranges in a tape till it is full.

how to Backup ISA Configuration with DPM2007 ?
The ISA Server configuration changes rarely and hence there was never a need to schedule “continuous protection” for ISA Server configuration, unlike your SQL or Exchange databases.
Nevertheless, if you want to backup your ISA Server configuration with DPM, I would backup the XML file to a shared folder, and configure DPM to pick up the file from that shared location. If you want to automate the creation of the XML backup in ISA Server, see this article http://www.isaserver.org/tutorials/ISA-Server-2006-Backup-Restore-Capabilities.html
