Two options:

(1) Centralise your backup solution
(2) Centralise your backups at each location, but manage, administer and support
from the central site.

(1) is better from a support point of view.  (2) may be the only option you have
depending on:
(a) whether your network can cope with the amount of data you need to send over
it on a nightly basis (within your backup window) and
(b) if it can't how much it will cost you to upgrade your network so that it can
cope

Questions you need to answer:
(1) How much data is stored on each site
(2) How much data changes on a daily basis(presuming that incremental backups
are the way you are going to go), i.e. how many Mb are we going to have to send
over the network to the centralised server?
(3) What the thorughput is from each site to the main site (worth testing rather
than taking quoted figures)
(4) How big a budget do you have
(5) DO you have any other applications that require increased network bandwidth
(6) etc, etc.

Get a consultant in!!

  Subject      ADSM Backup over the WAN
  :







We have several branch offices and we are planning to centralize our backups.
Right now, our WAN speed varies between 56K and 512K; we have a combination of
T1 line, Frame Relay and ISDN. We are loacted in New York and we have offices in
different part of the country - Dallas, Long Beach, Miami, etc.. What should be
the recommendations to effectively backup our branch offices? Cost is also an
issue.
Any input will be greatly appreciate.

THank you
