How does one recover the server's media database and/or index if there

We're running 7.2.2 on Solaris with Linux storage nodes (also 7.2.2).

In our case, we use file type devices on the server, so the server's
regular data is written to tape on the storage node, but its index and
bootstrap are written to a file type device on the server. The file type
device is labeled into the same pool as the tape. The data on the file
type device is then auto staged (daily) to a clone pool on the storage
node. This clone pool has both the indexes and bootstraps. Periodically,
that clone pool data is manually cloned to a different clone pool, so
the server's index and bootstraps are ultimately contained on two
separate tape pools.

If we needed to recover this data, what is the procedure? It was always
my understanding that NetWorker insisted on a local device for backing
up the server's index and bootstrap but not sure about recovering? Might
seem silly to be asking this question now, but this was the way around
not having a local tape device that was explained to us, and I know I
must have asked about recovery at the time but can't recall the answer
or recommended method. Just a curiosity but would be good to know as
soon as possible if there's something we need to reconfigure.

Have you ever wondered why NetWorker has this restriction on backing up
the bootstrap to a local device?

Yes, I've wondered.

The answer is that not having that local device makes it very difficult
to run mmrecov. By circumventing that restriction in the way you have
done, you have removed a safety valve that the designers of NetWorker
provided for you.

I wish they'd redesign it.

In order to restore this safety valve there are a couple of things you
could do:
(1) Connect a local tape drive to the server as recommended by all the
documentation and training.
(2) Amend your staging procedures so that you always keep the latest few
bootstraps on the local disk device, perhaps by cloning rather than staging.

If you needed to run an mmrecov with your current config you could
perhaps run mmrecov on another machine of similar architecture and copy
the files across, or you could temporarily connect a tape drive to the
server. You cannot run mmrecov from a storage node device.
