»Command: operator snapshot save
Retrieves an atomic, point-in-time snapshot of the state of the Nomad servers which includes jobs, nodes, allocations, periodic jobs, and ACLs for outage recovery.
If ACLs are enabled, a management token must be supplied in order to perform snapshot operations.
To create a snapshot from the leader server and save it to "backup.snap":
$ nomad operator snapshot save backup.snap
To create a potentially stale snapshot from any available server (useful if no leader is available):
$ nomad operator snapshot save -stale backup.snap

-stale: The stale argument defaults to "false" which means the leader provides the result. If the cluster is in an outage state without a leader, you may need to set
-staleto "true" to get the configuration from a non-leader server.
