- For general VE license mode, backup licenses are typically limited to a certain number of emulator runtime hours. The backup license server is only used for failover if the primary license server fails in order not to deplete the available runtime hours unnecessarily.
- For AutoVE mode, the two license servers act as peers between which the client database is synchronized. The total number of instances available on both servers determines the number of Charon host cloud instances that can be licensed from the license server pair. Each instance can connect to either of the two servers. However, if one of the peers fails and there are not enough available instances on the second peer, there is no backup for an instance trying to fail over to the second peer due to failure of its primary server - and the emulators running on this instance will fail. The license on the server designated as backup server can be a countdown license (specified number of runtime hours) or a normal license.
The example below shows the output of a time-limited license:
