12 Failover Groups

Failover groups consist of associated protected servers and spare servers. If a protected server experiences

hardware failure and cannot record video, ESM automatically fails over the recording configuration to a spare

server. When the protected server is restored, recording switches back from the spare server to the protected

server. You can also manually failover to a spare server if you need to perform maintenance on a protected server.

The following configurations are included in failover:

 Cameras

 Recording schedules

 Users

 Event Linking

 Saved layouts, views, groups, and maps

 Serial profiles

 Archiving

 Notification rules

 Auto Export rules

The following configurations are not included in failover:

 System IP address

 Storage (recorded video remains on the system where it was recorded)

 Analog cameras

 Camera licenses and software agreements

Each protected and spare server can be included in only one failover group, and each failover group must contain

at least one protected server and one spare server. If multiple spare servers are available and a protected server

fails, ESM selects the available spare server that is most compatible with the protected server. The Failover Group

List shows the number of spares and protected servers in each failover group:

1 2 ... 29 30 31 32 33 34 35 36 37
