Renaming UNIX files for Windows

[Kevin Cook]

I am a new rsync user and am running the client on Solaris and the
server on Windows 2000 Server utilizing Cygwin for the Linux emulation.
Unfortunately, the log files I am backing up frequently use a ':' for
date/time stamps; colons are supported in UNIX but not Windows.  Without
having to recode my application, is there an easy way to have rsync
eliminate the ':' or replace with an '_' during a backup?

Thanks,
Kevin
