Hi James,
Are you sharing the project between computers with other editors or just yourself?
If it is the latter, I do this all the time. I have found the best solution to be a program called sync folders pro.
My setup is as follows.
Event on raid in the studio, connected to editing computer Imac.
I frequently go to my clients offices to do the edits so what I do is create a work folder on my laptop and use sync folders pro to sync my project folder for client from the iMac raid to laptop in target disc mode. This has me up to date with any files, edits up to sync point. I sync early on so the big files are transferred in the background, then just before I leave for client I sync again to have the latest version on my laptop. It only syncs the changed files which in this case is usually the project file, so it takes a few seconds.
I then do my edits on the laptop and add pickups etc at client site,
Come back to my iMac, connect in target disc mode again, and sync, but this time choose the other direction.
This way everything stays in sync, and also any notes I may have added or screenshots etc are added to the client folder on raid too. I also now have an exact clone of my clients project folder so everything is backed up.
Sorry if this doesn’t apply to your situation exactly but might be of use to someone else
