Subject: Re: [Veritas-bu] Questions to ask a Netbackup Admin on an =
interview
*interesting*
I know there have already been a number of posts for this and I agree =
with
the folks about looking for someone who can think and not just recite
things, but at the same time am completely tired of hearing from people =
who
claim to know "NetBackup Exec" or "NetBackup 8.6" (the Backup Exec =
version).
If they say they have NetBackup experience on their resume and they =
can't
tell me the difference between a volume pool and a volume group, then
there's a problem.=20
Asking the error number questions can be ok because when they do get =
stuck
you can always ask what they would do to figure it out (or see if they =
bring
this up on their own). I can't count the number of times someone has
automatically answered "pick up the phone and call support" instead of
looking in the manual or using bperror or something first.=20
Anyway, since I already had it typed up somewhere, here are some of =
mine.
many are leading questions, where the answer could be simple or turn =
into
something really long (depending on their level of knowledge of the =
item)...
How do you configure a client for automatic backups?=20
What's the difference between diff incr and cumulative incr? What =
happens
when I mix them on Windows client... Unix client?=20
How is a changed file determined on Windows and what happens afterwards =
for
each type of backup? How is a changed file determined on Unix?=20
When would I, or would I not, use cross mount points?=20
What is the difference between a Volume Group and a Volume Pool?=20
How do you back up the catalog? Why is this important? What do you =
have to
do if you don't have a catalog backup?=20
How do you recover the catalog?=20
How do you configure retention levels for a backup?=20
If I install the Admin client on an NT workstation, what else has to be =
done
for it to work... be an authorized server?=20
What is multiplexing? What is multiple data streams? Are they the =
same?
Can I have one without the other... both... ? where are they =
configured?=20
What determines the number of jobs a client can run? What determines =
the
number of jobs that will go to a single drive?=20
What is OTM? TIR?=20
What format does NetBackup write the tape in?=20
How does NetBackup tie together with Media Manager?=20
How do I create a Storage Unit that will only be used by one client?=20
What is the difference between the expiration date for a volume in
NetBackup's media catalog and Media Manager's volume database?=20
What is the process in which NetBackup decides if a tape is available =
and
which one it will use? Will media servers share tapes? Will retention
levels be mixed on a tape? What happens if the requested pool is out of
tapes?=20
What is the difference between a frozen volume and a suspended volume?=20
How many Robot Control Hosts can a DLT tape library have?=20
What does the bpbkar process do? bpsched? bpbrm? bpdbm? ltid? What
process controls a DLT tape library... a DLT tape drive? What is the =
AVRD
process?=20

backups
what command would you run and where would you run it?=20

so
that all four databases get sent to a different tape drive at the same =
time?
