Do you mean a "hot" standby where the "failover" is automatic, or where the
failover is manual.
A "hot" standby is rarely required since CVS is very reliable (and fairly
simple). To keep a "standby" use something like unison or rsync to keep a
second server in sync.
CVSNT (free/GPL, unix/linux/windows/mac etc) starting at 2.5.04 has a "write
through proxy" that facilitates a "hot" standby - the "caching" server acts as
a proxy for write requests and can be configured to rsync or unison to the
primary server at every commit. If the primary server is available but you are
performing a "read only" operation then it can use the proxy. If the primary
server goes down then the proxy can become the primary server.
But I want to stress - none of this is common and therefore none of it is
really required - even for a large (>500 users) system.
