Disaster recovery publisher
|
|
| voip@mrga.ch 2007-12-28, 1:12 am |
| Hello
we run a Callmanager 4.2(3) Cluster with 6 servers (1 pub / 5 sub) and are
planning a disaster scenario where we loose our publisher. Every night we write
a BARS backup. So the backup data will be available for a restore.
If I set up a sever with the same software (OS / CCM / Extended Services / BAT /
TAPS / Locals / Service Packs) and the same IP and name information is it
possible to restore the BARS backup to this server? What are the subscribers
doing if the publisher has an older database than the subscribers?
For testing, can I just switch of my publisher restore the BARS to the backup
publisher and test the cluster and then switch back to the old publisher?
Â_
Thanks for help
And have a happy New Year

| The subscribers will get the info from the pub and have their
databases overwritten.
If you are looking to test, do what you plan on an isolated VLAN so it
doesn't hose your network.

| I have run into issues before, but doing a republish on DBLHelper
usually fixed it...
