Hi Gennaro,

For the MySQL you can setup the replication in order to have the data synchronized by your servers.

Here is an example for master-master replication: https://www.digitalocean.com/community/tutorials/how-to-set-up-mysql-master-master-replication

Hi,
I'm using EPICS Archiver Appliance (https://slacmshankar.github.io/epicsarchiver_docs)
to gather EPICS PVs published by some Linux embedded systems
(~100 PVs @ 0.5 Hz);

the software is very feasible and has a lot of interesting features,
but I'm looking for a way to "mirror" EPICS Archiver Appliance collected
data on two different servers;

in details:

- the first server is on the same LAN of IOCs and it gathers PVs with
   default mechanism of EPICS Archiver Appliance - in this LAN, due to
   some network restrictions, it is possible to communicate with other
   LAN/WAN _only_ through an HTTP proxy;

- the second server is located on a different LAN and WAN (= no PV
   gateway is possible) and it has a public IP address;

I would like to collect on the second server all data gathered on the
first server;

I was thinking to sync (rsync) "/arch" directory between two servers,
but I suppose that MySQL tables should be sync too....

Thanks in advance,
Gennaro
