Are you actually backing up via network on
DP? That is to say are you sure it doesn’t have its own fibre
connections to your tape library or other storage medium?
NetBackup allows you to do that with “media
servers” and in our environment we have most of our big HP-UX 11.11
servers doing that. Our master server up through NBU 6.5.4 was
HP-UX 11.11. (With 7.1 we had to go to Linux master server as it
still allows for HP-UX media servers but not a master server.) We
do a daily backup of over 4 TB to Quantum DXi and also to tape concurrently
from one our HP-UX 11.11 media servers and both of those finish in less than 7
hours. (They would finish more quickly if not run concurrently but the
overall job time doing them sequentially would be longer so we chose to do them
concurrently.)
100MB LAN backup would be very slow
especially compared to a GigE network (which most HP-UX servers have available
cards for) so even if not doing the above the VLAN you’re using could
make a significant difference for a network backup.
Is DP doing some form of
deduplication?
Are you comparing an incremental backup on
DP to a full on NetBackup?
Is the DP backing up directly from the
source server like your test on NetBackup? (That is to say it is
common in large DB environments to do something like EMC’s BCV/SRDF or
Hitachi’s Shadow Image so that you are in essence duplicating the drives
to mirrors, splitting off the mirrors, mounting the mirrors elsewhere and
backing up from those mirrors rather than the source.)
By the way HP-UX 11.11 (a/k/a 11iV1) has
been EOL for some time. Also HP quit making the PA-RISC chipset
that ran HP-UX 11.11 at the end of 2009. You might want to suggest
to your management that they start planning for moving to something newer. HP’s
newer systems run on Itanium and some of the older ones could be converted from
PA-RISC to Itanium.

Subject: [Veritas-bu] Advice on
HPUX 11.11
Hi, I wonder if I can get some unix advice!
Looking at moving Unix from Unix Data Protector to NBU 7.0.1
As a test, installed a client on HPUX 11.11 and performed a
test backup of their selected folders.
It took over 16 hours. yet DP could do the same in 4 hours!
Bit gobsmacked really. Also found out it is on a different
vlan running 100mb, but the results are not good from their point of view.
Not knowing Unix that well, is there anything I could ask someone
to check / verify as to why it was slow?
Regards
Simon Weaver
