Hi Alicia,
You should backup the MySQL DB (check mysqldump), /opt/jffnms/rrd/ and
/opt/jffnms/conf/jffnms.conf
The rest is just PHP code.
Data is only written to the .rrd files, and we keep data-points for a year,
after that data is rewritten NOT saved anywhere. The .png's are just generated
on demand when you request a graph.
The images/temp folder should be cleared by a cleanup script that uses tmpwatch.
You don't need to keep them.

Hi, I've got JFFNMS 0.8.1 working on Debian since September and I'd
like to make some security copies of the most important files and JFFNMS
configuration data just in case "a disaster" happened. My problem is
related to all the data which has been collected by the pollers. I know
that all the data which a poller collects is passed to its corresponding
rrd file and the .png images that you can get when you want to see a
graph is obtained from these rrd files. Well, a rrd file is a Round
Robin Archive which stores data every "x" time and it doesn't grow in
size, so there's a moment in which you have to rewrite old data (as it
is "round"). My question is: Where does the program store that
information which has been rewrited? There must be somewhere because if
it didn't exist I wouldn't be able to get graphs from September.
I also know that in /var/lib/jffnms/tempimages you can find all the
.png files that you've got since you requested a graph from the first
time. And what's more, it worries me because you can't delete them and
this directory keeps on growing more and more. What can you tell me
about this?
Thanks in advance.
Alicia Caminero.
