== Manually updating a Dynamic controlled zone ==
''"If you have to edit the zone files of dynamic zones manually while the DNS server is running, you'll have to freeze the zones with '''# rndc freeze <myzone>''' before editing and unfreeze them with '''# rndc thaw <myzone>''' after editing. This is because named(8) has internal state information and external journal files attached to dynamic zones that have to be kept in sync with the zone files<ref>https://forums.freebsd.org/threads/dynamic-dns-with-bind-and-isc-dhcp-server.33849/</ref>"''.

= Rsync = 

To delete files in the target if they disappeared from the source, then add the --delete option to your command. For example:

rsync -avh source/ dest/ --delete<br>
NB: -avh is for --archive --verbose --human-readable<ref>https://askubuntu.com/a/665918</ref>.
