I use Paragon Drive Backup Professional 9.0 on a pc (Vista Home Premium), that runs a cyclic (differential type) backup on a schedule three times a week. It is setup to keep 4 images, if the specified amount of disk space allows. The base image is about 60gb. It has been working fine for weeks, and as expected, the differential size has grown now to about 10gb in size. Of course, it will continue to grow, until I do something about it. My goal is to automate this as much as possible. I know that one of the purposes of a synthetic backup is to merge the base with the latest differential, but in looking through (and actually running it), I didn't see a way to specify the destination on the synthetic in such a way that the next time the cyclic backup runs it would recognize the "new" base image (created from the synthetic), and do differentials from that. Could someone walk me through that process? Is it necessary to modify the script file to make the cyclic recognize the base created from the synthetic backup? Do you have to run the wizard again to setup a new script when you create a new base?
