Neverless, I normally excersice a massive cleanup campaign prior to creating a new backup image.
I clear all cookies, Temp files, Temporary Internet Files and run [B]chkdsk[/B] on the partitions to be backed up.
Additionally, I disable System Restore, reboot, and re-enable it to reduce the capacity of the System Restore files.
This is only recommended if you are confident that your system has no current issues and the previous restore points are no longer required.
I normally purge any Restore Points prior to my previous backup image creation.
This is followed by malware and anti-virus scans prior to imaging.
This accounts for a smaller image file and ensures that previous baggage is not transferred.
