Hi Bob. I have been playing with Unison and it definitly looks promising. I have had, though, a few quirks with it: - It seems to me it is pretty slow. I know it might need a settling time for the first scannings but the "propagation" (as it calls the copying, I think) seems to be painfully slow. - I had a crash of the client application, caused by the sudden and unexpected stop of the server. My setup: two computers on a LAN, main uses Windows 7 and backup uses Windows XP. I started the unison.windows32.textui program as a server on the XP machine, adding the option -socket 5432 in the cmd console. Then, I run the unison.win32.gtkui client on the Windows 7 box and config it to connect to the 192.168.0.111:5432 server (the XP box) and to sync from the W7 disc E to the XP disc E. Everything starts fine but after around 1 hour and after the "propagation" of 15 GB out of a total of 65 GB, the two previous problems arise. Regards, Carlos. ------Mensaje original------ De: Bob Blick Remitente:piclist-bounces@mit.edu Para:Microcontroller discussion list - Public. Responder a:Microcontroller discussion list - Public.

Been there, done that, switched to Unison when I needed to do it last time, haven't looked back :) Also, twice a year rsync in Windows would insist all my files had changed and copy all of them. It coincided with the Daylight Savings Time change, and nothing I did ever fixed it.
