I've been using HDM 15 for a few months and everything seems to be working quite well (video editor). I created schedules that include incremental backups from RAID arrays to attached storage. However, I need to trim the size of my backups as they are getting quite large. In my mind, the ideal way for the software to work is to overwrite everything X weeks of age. I don't think HDM works like that, however, so how does one safely and efficiently keep the sizes manageable? Thanks.
