>From the description its unclear if this SAP Server is a "lan" based
client or an actual "SAN Media Server".
A San Media Server (that is the SAP System backing up itself) and having
direct access to the Tape Library using SSO over the fabric would help.
But again, this assumes the client is not a SAN or Media Server itself.

Subject: [Veritas-bu] Large SAP backup problem
Hello,
I have a problem with one backup, this backup now have more than 10 Tb,
it's a SAP base backup, my problem is because this backup take more than
36 hours to finish, the throughput is not bad, its do 4 jobs with 15Mb/s
per job totally 60Mb/s but my backup window is only 13 hours for 06:00
PM to 07:00 AM and I don't know what I have to do to take this backup
more fast. Below the description for my environment.
I have one NBU master Server Solaris and 3 media servers with NBU 6.5.2
in all servers and clients.
One media solaris attached to a SL500 library with 7 drives One media
solaris attached to the same SL500 and a VTL with 24 virtual drives One
media AIX attached to a VTL with 48 virtual drives
The AIX media server is on a P595 and these is the same machine than the
server I need to backup, there is a Shared Ethernet Adapter controlled
by a Virtual IO server to shared all the network card for this P595 to
create the backup network.
I tested these backup with all the media servers, VTL and SL500 and it's
the same throughput.
I tested with 2 jobs, 4 jobs, 9 jobs and it's the same throughput.
Tested multiplexing, the same throughput.
Online and offline backups, the same throughput.
I have a SAP client to do this backup, and I think the AIX media server
is the best to do this because it's the same machine, and my question
is, there is other way to do this backup more fast?
Thanks,
Atenciosamente,
