Hello all,
my Knot DNS is now in production and I would like to setup some
backup tasks for the configuration and of course keys. Are there any
recommendations regarding backup? And restore? I can see that it is very
easy to dump current config but I am to sure how to backup keys. What do
you recommend? Save the content of /var/lib/knot on a hourly/daily
basis? I am not using shared keys.
Thanks
With regards
Ales

Hi Aleš,
you can simply backup the 'keys' directory (containing both the LMDB
with keystore and the subdirectory with pem files), possibly
incrementally. I would simply set the period of backup for
DNSSEC-related stuff to be less than propagation-delay in your config. I
would slightly recommend to backup everything (including zonefile,
journal, ...) together, provided if it's not a problem due to e.g. size.
When restoring from backup, it would be good to have Knot turned off.
Shared keys don't matter, since everything is on one place for all zones.
