There's a process that Veritas provides to run a backup job to nul that logs
the throughput... This should be able to tell you if its NBU or not.
1. Create log dir for bpkar - On the client
"<install_path>\NetBackup\logs\bpbkar"
2. Next, run the following command:
<install_path>\Netbackup\bin\bpbkar32 -nocont <backup_path> > NUL
2>c:\throughput.txt
(Where <backup_path> is a subdirectory which contains approximately 100 megs
of representative files.)
3. Once this throughput test has completed, the bpbkar logging directory
should contain a log and the throughput.txt
Hope this helps

I´m using only one stream, actually.
I would be glad if I could got 30 MB/s or a little less...
but 12 MB/s is not acceptable.
thx

How fast does a single (one stream) backup jobs run?
I'm wondering if you're thrashing the disks to hard with 8 streams.
BTW, 70MB/s is a stretch for LTO2.
IIRC, I thought the spec was 30MB/s native / 60 MB/s compressed.
I don't think I've seen over 40MB/s per drive.
