Hello all.

We are in the process of upgrading our VAX based infrastructure to NT 4.0 
servers on Intel processors with NT 4.0 workstations on the desktop.  We have 
21 sites in the UK which all have a LAN bandwidth of 100 Mb/s.  All these sites 
are networked together over the WAN with bandwidths ranging from 128 Kb/s for 
the very small sites (2 - 3  NT servers) up to 2 Mb/s for the larger sites (15 
NT servers).  The idea is to manage everything from a central systems 
administration site.

Our backup strategy requires that we will back up all NT servers and the 
storage management tool we will be using is ADSM V3 on NT.  However, because of 
the constraints of the WAN bandwidth, we are forced to deploy an ADSM server at 
each site with its own DLT tape library.  This will then be responsible for 
backing up all NT servers on that site via the LAN.  

My questions are as follows:-

Does anybody else have a similar situation to this? 

What sort of problems could I expect in remotely managing several ADSM servers 
(and the associated tape libraries)?

What are the issues concerning the offsiting of storage pool copy and database 
backup tapes for disaster recovery purposes (i.e. server to server 
communication)?

Anything else I should think of?

Regards

Phil
