Please add the ability to specify the maximum number of images to save, deleting the oldest version once that number is exceeded. Also allow deletion of old backups by age in a number of n(days, weeks, months). Thanks.
Unless I misunderstand, these options are already available. When creating a backup definition file fill out or verify the information on the first page of the "Disk Image" window. Click Next. On this page you will see a summary with a link in the lower left corner labelled Advanced Options. Clicking here opens up a new window called "Advanced Settings." Click on Disk Space Management and you will see options to "Automatically remove full backups from the destination directory if they are older than X days or weeks and Keep a maximum of X full backups, followed by whether to purge before or after the backup.
