I have a client who wants to syncrhonize files over a permanent branch office ipsec vpn tunnel.
For example, if he makes a change to a file at Site A, the change will be propogated to the same file at Site B.
Also, if he adds a fiile at Site A, the file should be added to Site B.
Of course, if he deletes a file at Site A, the file should be deleted at Site B.
This applies in the reverse direction too, i.e. changes at Site B are replicated to Site A.
The primary purpose of ths is to back up files, but I do not want to use a backup program because I want the client to be be able to see the state of the files just by looking at the filesyste; not just a big. bkf or .arc or other backup file.
The file sync will be between a 2003 SBS Std. Server and an XP machine (not sure if Home or Pro).
This program must be user friendlyl, as a non-technical user will be using this.
Software that is free is preferred.
