Karnash,
So many questions! I've replied within the text but you should
seriously consider going on a training course. A 5 day introduction to
Networker (and the backup world in general) would repay dividends.
Good luck
Bob

You would have to recreate your backup server at the DR location by
building the appropriate machine(same hardware and OS0 the doing an
MMRECOV from the tape with the bootstrap record on it. (See EMC website
and look at the DR documentation)

As above, you would recreate your backup server. Yes you will need a
tape device, it doesn't have to be identical to the original but as
close as possible helps with drivers, etc.

Used for importing or withdrawing tapes to/from the library without
opening the front door

You can order media that has barcode labels already applied (cost a bit
extra but may be worth it).
If you have barcode reader then, in the jbconfig, set the 'labels match
barcode' setting to yes. When you label a new tape networker will use
the barcode label as the tape label.
Cleaning tapes have a label that starts CLNnnn where nnn is a number.
If you set the library to autoclean then networker will put aside the
last slot for a cleaning tape (some libraries have a specific slot for
cleaning tapes)
Or you could leave it out and import and load it when cleaning required

Shelf life? Well there are varying views on this. Some say that, due to
the earth's magnetic field, tapes loose 10% of their ability to retain
data each year. Others say replace every 5 years.
It is up to you, how important is the data? Important enough for you to
copy it from one piece of media to another every few years?
How do you know if data is still ok? Do a sample restore, this will give
you a good indication of whether the media is deteriorating or not.

Using a platform you are familiar with is certainly an advantage. To
move from one OS to another you will need to get in touch with your
reseller and arrange a transfer (there will be costs associated with
this)

Isn't it?

Cloning is making a copy of the data (for such purposes as sending
offsite so you have the data onsite for recoveries if required)

If you really want to be prepared you should convince your boss to fork
out for some training

There are many companies making lots of money doing just this, I suggest
you do a bit of research yourself (start with a google search on
disaster recovery plan and see what you get.
As far as having a test machine, yes it is a good idea, get used to
doing bare metal restores, restore a different client each time so you
get to experience any quirks associated with that client, document the
steps you took and the issues you encountered. These notes will form the
nucleus of your recovery plan.

This is all documented in the disaster recovery documentation on the EMC
website

You need to get some formal training, there really is no substitute for
it.
