For example, this server may be referred to as a standby or secondary server (among other names).

SDS or HDR secondary node can take over primary, and RS secondary server continues to receive logical logs from new primary server.

A copy of information specific to a given primary or secondary server is also stored locally.

Then, when you switch to the secondary server, you can simply update the instance of Notification Services and start the instance.

Copy any uncopied backup files from the backup share to the copy destination folder of each secondary server.
