Ed (and others), how's it all going with 6.0 MP4?  I'm still with 5.1
(MP6) but I'd like to use the improved staging capabilities of 6.0.
Using RHEL 4, Update 4.  Someone mentioned that 3-way NDMP performance
was worse but I'd like to hear from the list how MP4 is going in
general.

Regards.

About a week ago I downloaded MP6 for NetBackup 5.1 in response to a
security bulletin ( http://entsupport.symantec.com/docs/285082 ) issued by
Symantec. It went on fine and things seem to be working ok, but I've
noticed a couple bits of strangeness:

1. The status monitor no longer shows what path/file is currently being
backed up; the field is blank. The Pathname field in the job field box
that appears after clicking on an individual job is also blank.



Yeah.  I installed MP6 to address some annoyances I've seen with disk
staging.
The "path last written" in bpdbjobs output (and therefore also in the gui)
is now showing part of the bpsched debug log.
Now I'm wondering what else they messed up.

2. NetBackup sends out emails for each client that completes (or fails)

backup. The subject line is now blank, or very minimal. The client name
used to be part of the subject line.



I don't use the email feature.  Can't commment on this.

Anyone else notice these things?

Re: [Veritas-bu] Backups vs archives

2006-12-08 Thread Tim Berger

On 12/7/06, Curtis Preston <[EMAIL PROTECTED]> wrote:


Based on some previous posts, I'd like to throw out the following
thought, and see what you folks think about it.



Thanks for posting to the netbackup list, this is a great article.  My
thoughts on this are the following.

Netbackup's archive feature

I've never cared for netbackup's archive feature because it mechanizes
removal of data.  Removal of data should only be done manually and
with great care.  Bugs like this one (
http://entsupport.symantec.com/docs/284450 ) reinforce my dislike of
systems that perform automated removal.  But I agree that the process
of doing backups should not be the same as performing archives.  They
are two different things.

Critical metadata required for recovery

For both backups and archives, the single most vital piece of metadata
to me is automount history.  Data inevitably gets moved from one
storage server to another or from one volume to another.  Users don't
know or care where it lives, all they know is that they need
/proj/roswell/autopsy recovered from 1/1/1999.  Backup/archive
systems probably only know about it's current true location,
blackhole:/vol/vol0/autopsy.  Everyone should keep a running history
of all automount map changes.  (I can share the scripts I've got, but
they're site-specific).

Poor man's archive server

I work at a small company.  Here's what we do.  Clearly this is not a
great system but it has some advantages.  A request comes in to
archive a home directory or engineering related project files.  We
copy the requested data to inexpensive big disk raid5 systems.  These
systems get backed up periodically such that there's never more than
two copies on tape and they have little overlap.  We periodically run
updatedb so that a single file can be found with locate.  When copying
we keep the entire path intact.  Other metadata retained: md5sum of
each file, original server name, volume, archive date.  This has none
of the other great advantages that a CAS or HSM system might provide,
and filename search doesn't scale well for multiple archive servers.
A search layer can be added above locate to use each archive server's
locate database.  This is on my to-do list. ;-) In many cases a
request comes in to recover monster-spreadsheet.xls but they don't
always remember where it used to live.  locate is extremely useful in
cases like this.

Final Thoughts

Modern CAS systems look very appealing.  A CAS system would be too
expensive for all our general purpose data but I'm going to seriously
consider one for at least financial data.  For small data sets a
combination of rdiff-backup and rsync for replication might just be
enough to do the trick.  In any case today's commercial CAS systems
look great.  I'd be interested in hearing about experiences with them
from anyone on the list.  Email archiving is another thing I really
need to look into using at our site.

Cheers.

cheers, PhilDue to the demanding nature of disk staging you never want to read and write concurrently.   This will definately kill performance no matter what disk type is used.  Hard drives have sets of heads that can only be in one place at a time.  This is not a SATA vs SCSI issue.  For high performance operations you don't ever want them thrashing around.  It's certainly possible to throw money at the problem to buy faster disk, but I'd argue that you're better off using the money for more staging space to avoid concurrent reads and writes.

Detection and correction are two different things.  With sw raid, a persistant bad block is not always recoverable resulting in failing out a disk or hanging your system.  Hardware raids can remap them on the fly.

Agreed.  70MB/sec writes is disappointing but acceptable for my requirements.  On a fast cpu machine you'll see better performance with software raid.  That's normal.  There's lots of other reasons to go with 3ware.  Here's what led me there:
- Auto-sector repair.  With big disks, this is critical.  I've lost software raids in the past due to latent bad block loss that led to more than one disk getting failed out.  All big disks have this problem.
- Very reliable driver support.  smartd support.- Hot swap support, good management interface.Software raid is good for some things, but I would not use it in a machine that requires high uptime.  Each of my media servers has 24 400GB drives so ease of managment and reliability is critical.  I used to strictly use software raid.  No more.

Re: [Veritas-bu] backup speed

With LTO3, you *really* ought to be using disk staging if at all possible.  As someone already stated, the minimum speeds are quite high.  For IBM LTO3, it's 40MB/sec.  If you can't meet the mimimum speeds you're going to prematurely wear out your tapes and drives and of course, you're not making good use of these awesome drives.  I'm using Linux staging media servers and seeing up to 160MB/sec for 2GB fragments.  With this throughput, one drive per media server does quite nicely.

[Veritas-bu] Netbackup 6 and nearstore storage units with millions of files per qtree

2006-02-16 Thread Tim Berger
We're still at 5.1 right now, but I'm reading over the 6.0 docs, and
it looks like they've added a really useful option called nearstore
storage units.  Has anyone here tried it out?

We have 3 netapps that snapvault over to an R200 and we use NDMP to
back them up.  Some of our qtrees have several million files.  The
three problem qtrees have 12M, 17M, and 23M files in them.  It can
take 48 hours to snapvault them over.  Because the target then also
has millions of files, backup performance is horrible, and this is
still with AIT2.  Part of the problem is our R200 has 5400 RPM disks,
but I don't think this is the primary issue.

The problem is, we are migrating to LTO3.  We can't continue on this path!

It *appears* that nearstore storage units might help address this
issue because the target uses netbackup tarballs.  No more need to
create millions of inodes on the target and no more need to traverse
them to back them up.  If anyone has tried this out with millions of
files per qtree, please let us know if this new option has helped at
all.

Thanks!

> 1a) Do I really have to upgrade my clients to 6 before the server will

> 2) If I was running 6 on the 'old' system, could I follow the previous
> advice, and move /usr/openv/netbackup/db and
> /usr/openv/volmgr/database, run the proper vmglob and bpmedia commands
> on the new box and be done?
