I am running Paragon BR Free V10.1.19.16240 on a number of PCs. I would like to set up an automated system where I can take a full disk image on Sunday, then take differential backups each night of the week (Monday-Saturday) and keep 4 versions (weeks) of full + incrementals backups in 4 backup directories on external disk. I plan to name the backup directories and full image files with a version identifier in the paragon backup script. And then programatically changing the version ID in the paragon script each week, so that I can then rotate through the four versions, and then reuse the first version ... I can script some of the processes to rename the files and directories in the Paragon full backup script, but have a problem automatically generating the differential backup script. On Sunday my maintenance scripts will roll over the versions (basically remove all files in the version backup directory), so that my new full image backup will be placed in the oldest version directory. Now after the full backup completes, I need to automatically generate a differential backup script from the base that was just created. How can I generate a differential backup script using a command file? Another option would be to manually create a very first differential script, and then programatically modify the script each Sunday after the full backup completes. I just do not know what all I would need to do to get that done correctly. I also don't know if anything should be done to register/de-register the files with Paragon. Any help or advice would be appreciated.
