Sychronising PC's over remote locations

Whats the best software or system?

[caine]

Constantly backing up from my home pc and my works pc to transfer new work, and files. However, is their a way that this can be done securely and synchronised that at the end of a Sesh on the comp, that i hit an icon to a service that will upload to the opposing computer all the new changes, deletions or additions.

Any idea's, was thinking about PC anywhere on a 168 bit encrypted port tunnel, but not sure, any one done anything similar?

No. I did'nt see it, but not quite what i am asking.

My situation is very security conscious. I've a soft firewall on an IP at home, and a Hard and soft firewall on the network at work, which has a VPN in place, however, i don't want to leave a tunnel open, and i am not very confident in freeware or shareware, when it comes to security issues. I know there is no such thing as bomb proof security, but i am trying to get the best system, that is basically invisible, unless someone is specifically looking for it, and still versitile in what i want of it.

What about mounting a PGP Disk and then transferring the entire disk file via the VPN or FTP or similar? You could then re-mount the disk on whatever machine you're using. The file is encrypted, so the transmitting utility doesn't need to be all that secure.
