im trying to get a good backup going over my lan to a windows machine - I already have my data on a separate volume and then carbon copy my system volumes and data volumes to two volume son an external drive, but would like anothe rplace to backup to

I used to use a synch program in windows, which used to copy any changes over to the windows box - seems any backup program i use normally fails with either no mounted smb share or credentials (the permissions are completely open on the windows end guest write access).

Any suggestions? CC needs a key putting on the remote box.. but its not mac.
