A bit more, mostly telling me to use SMB instead, which is nonsense.

Every time I talk about Windows, you keep talking about smbclient. Nobody,
flat nobody that I know of is stupid enough to run SMB on a public
webserver. The windows machines in question are using amanda under cygwin.
However, having an identical problem on Linux proves that this isn't
related to Windows or Cygwin. I know you've got your head wrapped around
smbclient, so let's drop the windows and focus on Linux. Tar isn't
honoring the exclude files on Linux.

Just to clarify, the entire system (60gb+) is backed up every night.

Some versions of tar out there apparently don't work properly without the
equals sign. Search for it, or trust me. In any case, I agree that it
isn't affecting these linux boxes -- either syntax appears to work.

That's fine, I was trying everything possible. Right now with those regexs
I'm backing up 60gb a night from that system. Wouldn't that suggest
something is wrong? I started with just the first regex and added others
when it didn't work, so it isn't due to the bad regexes...
