Jochen,
I know that relocation within disk staging is restricted to one image at
a time per Disk Staging Storage Unit (DSSU). There is no multi-stream
capability as when data is backed up to the DSSU in phase 1. Veritas
recommend using multiple DSSUs to achieve increased performance within
the process.

How about:
bpimagelist -U -hoursago 99999 -client <clientname>|head -3|tail -1
That is, bpimagelist outputs images ("successful" backups) with most
recent first. "head" takes 1st 3 lines of output and "tail" throws away
the 1st two (header) lines, leaving the most recent backup line, that
might look like this:
08/24/2005 21:49 09/21/2005 13496 809836 N Cumulative I
SomePolicy
Of course, that doesn't say all the files of interest were backed up,
nor is it of much usefulness if a client is covered by more than one
policy, or if files are excluded/selected according to schedule.
cheers, wayne

How about occasional random restores of files? Your backups, after
all, are only as good as your restores.
(most of the time i use bpimagelist -- sometimes bperror -backstat )
Of course, if there's only 2 important files on a box and an admin
puts them on an exclude list - I would never know if they were missed
or not - backup was successful, but doesn't do much good if the
important data is missing.

I have a memory leak issue where I'm running out of swap. I haven't
found the cause. What was the fix you're referring to. I'm having the
problem on the two master servers running Solaris 8.

Paul,
We had the same issue here- turned out to be caused by a memory leak on
our Solaris Master server. Once the leaking application was fixed, the
150's went away.
The offending applicaition was the user interface to Veritas Volume
Manager. A fix has been issued, but we just shut down the interface
portion since it wasn't necessary for us.

Subject: [Veritas-bu] Staging performance vs. Backup performance
Hi,
We have a strange performance issue with staging from Disk to Tape.
Config:
Sun V440 as Master/Media Server
Storagetek FlexLine640 used as Staging Device
Storagetek L700 w. LTO3
SIZE_DATA_BUFFERS 2048k
NUMBER_DATA_BUFFERS 16
SIZE_DATA_BUFFERS_DISK 2048k
NUMBER_DATA_BUFFERS_DISK 16
When we use the Flex640 as a "normal" Storage and doing Backups from
Disk to the L700 Storage,
we see ~140MB/sec. throughput to one LTO3 (higher than expected).
When we use the same Volume on the Flex640 as an Disk Staging Unit an do
manual relocate to 1 LTO3
we only see ~70MB/sec.
When we are using two staging units on the flex and are staging to 2
LTO3 we see ~50MB/sec. per drive.
An overall of 100MB/sec.
Since Staging is done via bpduplicate, are there any settings that are
staging, or bpduplicate specific?
It looks like that there is an "internal" limit, because tape, disk and
system have spare resources left (enough idle time)
do you have an ideas?
thx
Jochen

Hello Jochen
I think that NET_BUFFER_SZ plays at part in duplicate as it can be done
between two media servers

Subject: [Veritas-bu] drive cleaning frequency change not sticky
Weird problem of the day: If I change my drive cleaning frequency in
the Admin Console (I believe it uses tpconfig under the covers), the
frequency reverts to the old value at the next change of media!
Workaround: If I use the tpclean command to make the change, the change
"sticks". (I'm lowering from 500 hours to 300 hours).
Environment: Solaris 9, NetBackup 5.1MP3, L700, LTO-1 drives, not
shared. NetBackup thinks TapeAlert is on, but it has never worked (the
L700 does see when the drives have "cleaning needed").
Just thought this might lessen the "astonishment factor", if others see
the problem.
P.S. Maintenance packs have been coming out quarterly, but v5.1MP4 seems
several weeks late ... anyone know what's going on?
cheers, wayne

Yes, perhaps that explains the TapeAlert problem.
