To have access to at least 1 fully recoverable, ideally very recent,
backup in the case that the 'main' backup(s) on the NAS are, for
whatever reason, 'bad'.

(1) Destructive, unrecoverable degradation/failure of the RAID array
(2) Physical destruction of the RAID array

Both have happened here in the past ...

And I'd like to integrate/automate this backup-of-backups into my
Bacula-centric backup strategy/procedure to minimize PEBKAC.

I can't quote you a specific failure rate.

The NAS device is a 4-disk RAID-10 array.  It's a software array; linux
md created & managed.

The Array is physically It's connected to its dedicated PC via a
PCI-mounted JBOD Sata card.
