i've got multiple xbmc installs, with one main one that hosts a mysql server.
the library syncing itself works fine, all xbmc's have the same library.

what i'd like to do now is sync the thumbnail cache of all xbmc installs, so they're in line with the server.

is there a utility/command I can use to do a one way sync of xbmc's thumbnail cache folder with the other installs I have?

main server - //192.168.1.40/home/xbmc/.xbmc/userdata/Thumbnails
other servers //192.168.1.x/home/xbmc/.xbmc/userdata/Thumbnails

I would look into using pathsubstitution in your case.
if you do go down that road of a central thumbnail share it will be slower compared to keeping the thumbnails on the local systems disks.

that's just it, I don't want to use a central thumbnail share, I want to take the thumbnails that are already generated on the server, and copy them out to the other systems, so they're all using local thumbnails.

The how depends a lot on the OS for the servers. I suspect your xbmc server(s) are linux, but what is the "main server" running? If that is also linux, then I would use rsync. If it is Windows, I can only wish you good luck in dealing with port 139.
