What's the difference between having a backup TServer and the High Availability option offered by Genesys?
-
Can you please specify what you mean?
Do you mean using TServer Backup Option as opposed to using First Watch to start a new server?
What do you mean by highavailability?

High Availability is an option offered to allow hot standbys of Genesys components, we are thinking on installing Network T's and the HA option was suggested.
Basically if one fails it switches over to the other one with out loss of data. With a normal back up there could be some loss of data before the backup started.

Jim,
I will only talk about Meridian here, but from what I understand, High Availibility option is using "redundant link" option, which, if I am not mistaken is Meridan Link 6.0.4. And, last time I checked, 6.0.4 was discontinued, and replaced by Symposium link, which, I believe does not support reduntant link connection, thus making HA option useless.
Whaty switch are you using?
For most of the sites configuration we have, we are using a monitoring software to START a TServer process on a separate machine, should a primary fail. For the rest of the components, such as Stat Server, DB Server, and so on, we are using a backup option, which can be configured in CME (this infamous "backup server" dropdown box under [Server Info] option).
I would suggest using IR nonstop operation, tied together with a hotstandby in combination with the backup option mentioned above for the Meridian. But I cannot speak for the rest of the switches.
I hope it helped!

On the Genesys Support site the Framework 6 Configuration and Installation document explains it well.
We are on a Lucent G3 so if we want to run hot standby looks like we need the HA.

How much is it?

The failover mechanism is the same for both types (tbsc for 5.1 or the management layer for 6.0) . Depending on the switch you have, you may need HA Proxy in addition to tserver. The advantage here is that both tservers are actively registered with the switch and maintain a synchronized state with each other. In the event of a failover there is no need to re
egister DN's or loose calls currently being served at a routing point by IR. (which is probably the most important point) with HA, IR can pickup where the previous IR stopped and execute strategies on all calls still waiting at the routing point.
