My SVN server is hosted on a remote Windows 2012 Server host and my need is to have a daily backup of the SVN sources database (plain folder copy). In order to achieve this I've got to tell the administrators which folders must be backed up.
I can find svnadmin in C:\Program Files (x86)\Subversion\bin but I've got no clue about where the actual sources are located.
Thanks in advance.
This is something only the administrator of the server can tell you.
If you connect to your repository via Apache (i.e. your repository URL starts with http:// or https://), look in the Apache configuration file for the URL or your repository. You can use the SVN Book as a reference, but the administrator should be looking for the SVNPath or SVNParentPath directives, e.g.:
<Location /repos>
DAV svn
SVNPath /var/svn/repository
</Location>
If you connect to your repository via svnserve (i.e. your repository URL starts with svn:// or svn+ssh://), then the path to the repository on disk was passed via the command line to start the process. Your administrator should refer to how the svnserve process was started to determine the path.
