Synchronizing a folder across 2 drives

[gadgetman]

I use the Synch function in Total Commander. It lets me see exactly what will be done before it does it and is *very* simple to use.

It will run from the USB stick too without installing locally.

I liked AllwaySync, the free version works for my use (starts whingeing if you sync too many files too often).

Now I use xcopy on PC and rsync on *nux, just work out the commands once and save on every medium for a copy/paste to the command line.

Another vote for rsync on *nix (which includes OS X). It really comes into its own when backing up over a network, for example when backing up websites and mail folders from a hosting ISP (you need ssh access for this).
