When you restore from the backup, everything is overwritten including the IP address,
certificates and the license.dat file. Therefore if you are restoring onto a different server from
the one that the backup was made on, you must manually copy the original license.dat file
and any certificates that are not valid on the new server. Note that the license.dat file is tied
to the MAC address of the server; therefore after the backup has been restored to the new
server, the license from one server will be invalid on another one.
6. Establish an SFTP connection with the standby server
7. Upload the previously saved original license.dat file back on to this server
8. If necessary:
a. Put back any certificates and private keys (if the restored versions are not valid on the
standby server).
b. Assign these certificates to their corresponding services using the following commands:
callbridge certs nameofkey nameofcertificate
webbridge certs nameofkey nameofcertificate
webadmin certs nameofkey nameofcertificate
xmpp certs nameofkey nameofcertificate
webbridge trust nameofcallbridgecertificate
c. Restart the any service for which you changed the certificate
xmpp restart
callbridge restart
webbridge restart
webadmin restart
After the new server has fully booted up, it will be fully operation and take over the services of
the original server.
Time for Swapping Servers
If the standby server is kept powered on, typical restore times for Acano servers are 6-8 minutes
(and for VM servers this is 2-4 minutes) to restore the configuration, copy the license.dat file and
