   If you're using the FSFS backend, then rsync will probably do nicely.

   I've also had "svnadmin dump -r N --incremental" running as a
   post-commit hook, which copied the dump over to the other server
   and did an "svnadmin load". Seemed to work well enough. You need
   another hook to handle revprop changes too. Rsync is a lot easier,
   but it gets progressively slower as the size of the repository

   We have a similar setup, however, the volume where the FSFS filesystem
   is located is on an EMC SAN of some sort, and it just magically
   "appears" on the failover server if the main server goes down
   (we have an entire department responsible for "storage").
   We just leave Apache running on both servers, and when a "failover"
   event occurs, the SAN moves to the failover host, and the DNS
   entry for the svn host is changed.
