Recovery, in case of a crash of the executable file or server with executable files, the orchestrator will redistribute the streams to the executable files of the working servers.
All the configuration of the orchestrator is stored in the orchestrator's database (MySQL-like). In case of using a database cluster, recovery of the configuration is not required.
If a database cluster is not used, it is recommended to regularly backup and restore using it.
Orchestrator backup can be implemented in an active/standby scheme.
Backup can also be provided by clustering the database (MySQL-like), including using a database cluster intended for VMS.
Backup of other components of analytics is not required.
