I am currently hosting my project on googlecode svn, but would like a copy of it to be hosted on another svn server (also on the Internet), can anyone suggest a better way to keep this backup and update?
Dump and synchronization will work, but it is probably easiest to use svnsync , assuming that you are using the copy server as read - the only backup and not the intention to do it.
Although I would recommend you switch to git , it is easy.
