So I tried it anyway:

In my main DNS server:

         zone "home.htt" {
                 type slave;
                 file "slaves/bak.home.htt";
                 masters {192.168.192.2; };
         };

I reload and there I see:

Sep 07 14:00:05 valeria.htt-consult.com systemd[1]: Reloaded Berkeley 
Internet Name Domain (DNS).

messages, 23 records, 1000 bytes, 0.020 secs (50000 bytes/sec)

And over on homebase:

Sep  7 14:00:05 homebase named[1133]: client 192.168.192.5#51888 
(home.htt): transfer of 'home.htt/IN': AXFR started
Sep  7 14:00:05 homebase named[1133]: client 192.168.192.5#51888 
(home.htt): transfer of 'home.htt/IN': AXFR ended

But no file /var/named/slaves/bak.home.htt

And yet on my DNS server, I can resolve homebase.home.htt:

# dig homebase.home.htt

; <<>> DiG 9.9.4-RedHat-9.9.4-18.el7 <<>> homebase.home.htt
