Hi,

This is my first post to the list. I've recently taken over management of a
window
servers backup setup and a large tape library (HP ESL9000). It uses
Networker 7.1.3, and I've been familiarising myself with Networker and how
it's been configured. 

We have clients, groups, pools and schedules etc, and run 4 backups a night:
an SQL and flat file backup of groups of production and development servers.
I'm used to running a simple small tape library where you put in the tapes
you want to use every night, and as long as they're past their retention
period they're overwritten. But this tape library setup has 6 tape drives
and about 200 tapes which mostly remain in the library, except that every
day the previous night's backups are sent off site to return in 2 weeks
time. when we archive 3 or 4 off every month for indefinite storage. 

I have two questions/issues:

1) The jobs ate staggered but not so much that 2 or even 3 can be running at
the same time. The result is that the night's backups are spread over at
least 3 tapes. These tapes can sometimes be expired tapes completely
overwritten, or contain as yet unexpired data which is appended to. This all
makes it very difficult to identify where the data has gone, and if tapes
are to be archived off sometimes older but not yet expired data previously
written to the tapes has to go off too. 
I would like to tell Networker to only write to blank/expired tapes, and/or
force it to write to specific tapes. 

How can I do that? 


Thanks,
