By default, Myth will select the "local" filesystem with the most space 
available for new recordings, where "local" means one accessible through 
the filesystem (whether an NFS/CIFS mount or actual local storage).  
(Note that you can affect its preference, making some filesystems less 
likely to be used, but that's another story.)  The only time the default 
rotation won't really work is if you have separate backends without NFS 
mounts.

On my system, which consists of 2 backends each with local-only storage 
and no NFS exports, I've configured cardinputs such that the 1st and 4th 
inputs defined are on the master backend and the 2nd and 3rd inputs are 
on the slave backend.  With that approach, the first recording to start 
gets input 1 and, therefore, writes to the master backend.  However, any 
time 2 or more recordings overlap, the 2nd and 3rd will be written to 
the slave backend's storage.  When 4 overlap, the 4th will be back on 
the master backend.
