This may have been covered a lot, and if so, I apologize. However, I think this is a good forum in which to address my concerns: Now that Mountain Lion has been out for a little while, I wanted to ask everyone's opinion on what the best third party software to do incremental backups of external drives to other external drives (both directly connected and over a network) is. I have been using Time Machine since it was available, but obviously that's only useful for the drives inside the machine, and until ML, would only backup to one drive at a time. Essentially my main use for this would be working on an external drive (or RAID array of drives) for FCP work (data, edits, renderings, etc.). I want to then be able to run a reliable, still and future supported, fully ML compatible third-party program that will allow incremental updates to other (encrypted) drives - either during the editing process or after I finish the work for the day - only backing up the changes since the last backup. At the moment I'm testing the Memeo software that came with one of my Seagate FreeAgent GoFlex 1.5TB drives, but its release notes say the last version was from 2008 ... I would love to hear success stories, failures, and current choices for solutions to try and to avoid. Thanks for your help.
