I was really surprised how easy it was to set up a slave backend.

Make sure the new master is accessible remotely over your network ie a 
remote frontend works fine.

Then starting from a stand alone combined front & backend.

Uninstalled the database as a slave uses the one on the machine to be 
used as master.

Altered the config.xml for the slave with the host name pointing to the 
new master.

Changed the master slave  setting in mythtv-setup .

When running setup on the slave it should now see the masters database.

You set up the tuners on the slave locally.

If you have sources defined on the master the slave can see them so you 
don't need to do channel scan.

The storage directories on the slave should all be blank in which case 
the system uses those defined on the master.

The slave should be setup so that it sees the file system on the master 
at the same address.

I shared the recording folder from the master using samba - works fine 
on a Pi 3B.

Recordings are then seamlessly accessible on the master .
