Explanation: The database query to obtain the images to synthesize for the given policy did not return any images.
Recommended Action: Ensure that a synthetic full backup has one full image (real or synthetic) and one or more subsequent incremental images (differential or cumulative) to synthesize. For a cumulative synthetic backup, there must be two or more incremental (differential or cumulative) images to synthesize. Adjust your schedules so the appropriate backup jobs complete successfully before the synthetic job is run. The scheduler does not retry a synthetic backup job that fails with this error code.
