we see is that if the filer is under significant load the backup speed takes a

other filers that are not so loaded push closer to 120. LTO

So, are you trying to back up a filesystem with lots and lots of small
files? If so, remember that NetBackup will try to enumerate all of the
files that you are trying to back up. We had a similar situation where we
were trying to back up a filesystem with 3.5 million files in 50,000
directories.
All,
We just added a new robot to our environment and didn't get barcode
rules set up right away. We now have a handful of Media ID's that are
missing the preceding letter. For example a tape labeled C01234 is
showing up with Media ID 01234L (the L designates LTO media).

I guess I would challenge the "best practice". "Easiest" isn't always
"best". One might argue that it is "best" to have all backups on a
single solution as newer or inheriting administrators 3-4 years down the
road may have no clue how to restore the old backups later if all they
know is NBU.

It can do - checkpoints are markers and ideally suited for large, large file
based backups. for example, if you are backing up 3TB of Data on a volume,
it may be prudent to have a "check point" enabled.
I usually have it set for 2 hours (I think the default is 15 mins!) and

"Performance" is a tricky word here. If you never have issues during your
backups then "performance" is worse for checkpoint backups. However if you
have any issue say 5 hours into a long backup for a database your end to end
"performance" is better because you don't have to redo the 5 hours.
If you aren't going to set up RMAN you need to do backups of the
filesystem(s) or raw device(s) where the dataspaces are defined. The
best way to do this is with the database completely down. This is
called a "cold backup". You can also do a "hot backup" by putting the
database in "hot backup"
Of course it does. Every checkpoint requires that netbackup stop and put a
marker out there. IF I use checkpoint, I only will use 15 mins as the smallest
number.

Good Day
I have asked to a full backup of our oracle 8 database
which is running in archive log mode. RMAN is not set
up and I was told to put the database in backup mode.
I am not a DBA and would appericiate your help if
someone can tell me the exact commands to run on the
database server (Tru64)
We use the user backup syntax (-st UBAK) ((NBU 5.1))
/usr/openv/netbackup/bin/admincmd/bpplsched ${CONF_POLICY} -add
${SCHEDNAME} -st UBAK -rl .
When the policy type is a DB agent the schedule type will be application
backup. Works for SAP and Oracle policies. Probably for SQL too.
