Subversion automatic Update

Hi,
    I'v just installed subversion at my company as an alternative to
SourceSafe. I'm with a problem( I guess...) when the issue is to commit
the new files. The commit operation is working fine. The files in
repository are being updated corretly, but to update the server, "the
production server", i'm using a script that makes a checkout of the
entire repository evey minute. I do belive there must be another way to
do that without need to use a script every singlem minute. If anyone of
you guys could help me I whould apreciate.
Tkx
