NetBackup: set exclude_list on Windows clients
Posted on November 30th, 2011
You need to set an exclude list for windows client using Unix Netbackup server.
# bpgetconfig -M win_client EXCLUDE EXCLUDE = C:\Program Files\Veritas\NetBackup\bin\*.lock EXCLUDE = C:\Program Files\Veritas\NetBackup\bin\bprd.d\*.lock EXCLUDE = C:\Program Files\Veritas\NetBackup\bin\bpsched.d\*.lock EXCLUDE = C:\Program Files\Veritas\Volmgr\misc\* EXCLUDE = C:\Program Files\Veritas\NetBackupDB\data\*
Then just append desired path to exclude and save the list back to client:
# bpgetconfig -M win_client EXCLUDE > /tmp/exclude_list.txt echo "H:\oracle\NWO\sapdata*" >> /tmp/exclude_list.txt # bpsetconfig -h win_client /tmp/exclude_list.txt

tape operation: Netbackup runs out of tapes.
Posted on September 2nd, 2010
Recently I’ve faced with the problem that netbackup system runs out of tapes. To find out what happened, we used bpmedialist report.
To view summary report of media usage:
bpmedialist -summary
ACTIVE FULL SUSPENDED FROZEN IMPORTED
39 155 0 51 0
Number of NON-ACTIVE media that:
5 - are non-active and not written yet
CLNU06 (FROZEN)
CP9032 (FROZEN)
FJQ884 (FROZEN)
KR8006 (FROZEN)
QXN569 (FROZEN)
44 - are currently EXPIRED
QXN523 expired 04/14/2007 00:00 (FROZEN)
--- SKIPPED OUTPUT ---
MF9228 expired 08/13/2010 08:00 (FROZEN)
71 - will expire within 1 week
KR8009 expires 09/02/2010 13:00
-- SKIPPED OUTPUT --
KI1998 expires 09/09/2010 02:00
1 - will expire between 1 and 2 weeks
QXN614 expires 09/12/2010 09:00
85 - will expire in greater than three months
CP9017 expires INFINITY
-- SKIPPED OUTPUT --
QXN611 expires INFINITY
Number of ACTIVE media that, as of now:
22 - will expire within 1 week
QXN590 expires 09/06/2010 02:00
-- SKIPPED OUTPUT --
QXN559 expires 09/09/2010 10:06

QXN606 expires 09/16/2010 00:03
11 - will expire in greater than three months
CP9027 expires INFINITY
-- SKIPPED OUTPUT --
QXN566 expires INFINITY
Summary by retention level of ALL media

“Non-active” tapes are unavailable for backups. They are Full,
Suspended, and/or Frozen.
“Active” are all the rest of your tapes that are not empty. NetBackup
will use them for future backups (with the same retention period).
The “are currently EXPIRED” list is probably of interest. These are
tapes that have no useful data on them, but will not be used for
backups. They are probably “frozen”. Hopefully you recorded why the
tape is frozen (NetBackup doesn’t record this, except for the case of
the errors file (view with “less +G
/usr/openv/netbackup/db/media/errors”)) so can deal with it appropriately.
Tapes in a non-active category eventually have their data expire
(expirations of infinity take longer) and the tapes automatically become
available for backups (unless frozen .. see above).
Tapes that become empty (all data expires), and are not frozen,
disappear from this report. Whether these tapes stay in their current
Volume Pool or go to Scratch depends on other factors.
So, we are going to unfreeze some of the tapes and find out WTF the INFINITY backups occupied large number of tapes.
To determine the reason the tape was frozen look at logs:
1. /usr/openv/netbackup/db/media/errors
2. bptm logs
To unfreeze all the frozen media except these which caught write error during save.
grep WRITE_ERROR /usr/openv/netbackup/db/media/errors | awk '{print $3}' | sort -u > write_error.txt
bpmedialist -summary > bpmedialist-summary.txt
for i in `grep FROZEN bpmedialist-summary.txt | awk '{print $1}' | sort -u`
do
if /usr/xpg4/bin/grep -q $i write_error.txt; then
continue
else
echo $i
fi
done > tounfreeze.txt
for i in `cat tounfreeze.txt`; do bpmedia -unfreeze -m $i; doneNext, we run bpimmedia -mediaid against INFINITY tape and revealed that there was a policy mistakenly configured with infinity retention period sitting on the tape. Policy name was oracle-archivelog.
To find backup ids of old backups:
/opt/openv/netbackup/bin/admincmd/bpimagelist -policy oracle-archivelog s -d 01/01/2009 -e 06/01/2010 -idonly
Then use backup id for manually recalculate expiration date of the backup
bpexpdate -recalculate -backupid oracle_1248262567 -d 0 Are you SURE you want to recalculate expiration dates on all images that meet the following criteria: backupid oracle_1248262567 to expire NOW Continue?(y/n)y
To avoid asking question use -force option of bpexpdate.
You can batch expire the backups:
for i in `/opt/openv/netbackup/bin/admincmd/bpimagelist -policy oracle-archivelogs -d 01/01/2009 -e 06/01/2010 -idonly | awk '{print $8}'`; do bpexpdate -recalculate -backupid $i -d 0 -force && echo $i expired; doneAfter last backup with infinity retention was expired the media contained it is moved to scratch pool and ready to use for backups.
Tape backup operation: swapping tapes
Posted on August 19th, 2010
Sometimes I need to pull large number of tapes from large tape library driven by Netbackup and replace them with fresh ones. Manual selection of media from Netbackup’s java GUI annoys me, so there is a small piece of shell code to batch eject of tapes from command line. Replace $HOST with your media server hostname.
#!/bin/sh if [ $# -ne 1 ]; then echo Usage: $0 [number of tapes to eject] exit 1 fi NUM=$1 MEDIA_LIST= $HOST=backup-server for media in `vmquery -w -a | \ awk '$3=="HCART2" && $7=="TLD" && $12 != "scratch" {print $1, $15}' \ | sort -k2 -n -r | awk '{print $1}' | head -$NUM` do if [ -z "$MEDIA_LIST" ]; then MEDIA_LIST=$media else MEDIA_LIST=$MEDIA_LIST:$media fi done echo $MEDIA_LIST vmchange -res -w -rh $HOST -rt tld -rn 0 -multi_eject -ml $MEDIA_LIST
After batch of tapes was loaded into your library CAP you will be prompted to empty the CAP and continue with eject.
*** Eject volume batch #1 is ready to be removed ***
remove 10 volume(s) from media access port(s) of robot number 0 now

Find free cells within tape library with Veritas Netbackup
Posted on January 20th, 2010
Suppose you have to find out which cells in your library are empty. It would be easy task when you have not too many cells. If you have library with 100 cells and more, this little script can simplify the task.

Monitoring Veritas Netbackup jobs with nagios and nrpe
Posted on January 20th, 2010
We need to be ensured that certain backup jobs finished at the time. Of cours we could run reports and read them, do you really waste 2-3 hours a day reading reports? It would be more practical only pay attention to that jobs which have not finished successfully and do not care about ones finished with error code 0.
