High availability of NetBackup services
NetBackup Flex Scale uses docker containers to run different roles required for serving backup/restore jobs.
The containers are guarded against the following failures:
Failure of the NIC hosting the public and private IPs that are required for communicating with other NetBackup services.
Failure of the file systems which are used to store the deduplicated data and catalog file system.
Failure of the node on which these containers are running.
If any of the above resources are found to be faulted, NetBackup Flex Scale fails over necessary containers to suitable nodes in the cluster.
