indices(Optional, string or array of strings) Comma-separated list of indices and data streams to restore. Supports multi-target syntax. Defaults to all regular indices and regular data streams in the snapshot.
You can’t use this parameter to restore system indices or system data streams. Use
feature_statesinstead
So the indices field had no effect on internal indices.. as I read it
So perhaps look at feature_state and include_global_state
I suspect you may want
include_global_state: false
and/or
feature_states: ["none"]
But I would read through all that it has changed since 7.x
Ohh darn.. is this restore on a 7.x cluster?
