Doing my PhD I work at three locations, an iMac at home, an iBook out and about and at my uni-supplied PC. My Pc work is saved to a remote disk so I have transferred my files over to both mac's using scp via the terminal. What I want is suggestions of how to keep about a Gb of files in sync with one another. I think .mac would work by simply putting all the files in one place but there's only 250Mb of space. Of course, having the files in three locations is a good thing backup-wise but surely there must be a way to automate the appropriate scp commands or some software to do it all for me? Can anyone recommend anything?
