Just FYI / Netbackup can backup on Windows via Archive bit or Timestamp.
Timestamp isn't a HUGE issue in this case, the only issue being that the
incremental will backup everything changed since the last incremental
(including anything changed but backed up by the full.)  Its not like
timestamps make this solution not work entirely.

If the client machines are Windows systems, then you could use multiple
masters.  If the client systems are anything else, you will have to go
with a Enterprise wide master and media servers at the branches.

Windows incremental backups in NB are based on the archive bit (unless
someone has done something not very wise).

The other OS systems use the time stamp of the policy to determine what
to include in the incremental.  The policy info is stored on the master
server in the image database.

One big word of caution:  make sure that you can do multiple full
backups without have to use the same tape over.  You don't want to use
the tapes for your current full backup to do you next full backup.  If
an error occurred, you would have no full backup at all.

If you are using multiple masters, they just need to be in the bp.conf /
registry.

Same for media servers.  They just need to be in the bp.conf / registry

Hi All,

I am designing a centralized backup/restore solution for 100+ branches.
We are currently using NetBackup to do the data backup at a local tape
library attached to each branch server. Our business folks do not want
to mount/unmount tapes for weekly and incremental backup. So my task is
to find an innovative way to solve this tape handling problem. We also
have a very strict SLA for data restore ( 4 hrs) with business. 

I am wondering if I can keep the local tape library in a lock down state
and use it for weekly full backup (i.e overwriting tapes) and do the
incremental back at the central site. This means that each NetBackup
client needs to talk to a Master and Media Server for the Full backup
and then talk to another Master/Media Server for incremental backup over
the WAN.  Can a NetBackup client configured to talk ot multiple Master
server?  IF so, what is the way to configure it? 

My Branch servers are all Win2003 Servers and have medium speed WAN
link.
Any insight to the proposed solution would be much appreciated. I
exhuasted seraching NetBackup documentation and I could not find an
answer (yes/No) to my question. I hope Fourm members can anser to my
question based on their experience. Thanks
