We have been using ArcServeIT version 6.61 for some time with great success. However, every full backup that is run is unsuccessfull with an error message of AW0006 - Skipped non-fixed disk volume. Although we can restore from this backup I would still like to know how to make it so that our Friday backups reflected successfull. We are backing up the same files all week long as we do on Friday, except Friday's is a full while Mon - Thurs is differential. Any suggestions?
