I have restored CUCM publishers in a test lab before to be more familiar with the process, never had any problems. However, I would like to know more about the impact of a restore in a production environment. Currently, no call control or registration is being done on my production publisher - it's only purpose is to maintain the database. If the publisher goes down, I have nightly backups to restore it, but I'm wondering what the impact would be if I restore. For instance, if I use a previous evening's backup and I've already added phone since, what will happen to those phones after the restore? The subscribers are supposed to maintain a limited database of customer-facing features, I doubt the new phone information will be honored after the restore. Also, it's pretty standard that after a cluster is built out that, under System>Server each host is renamed to its IP address. When a new publisher is created, after it's brought up and before it's restored, it will still have its hostname. I'm assuming that the restore will change it's own hostname under System>Server so that the subscribers will be able to rejoin it and resume replication?
Can anyone recommend a good document on these implications?
