[Veritas-bu] slow performance on 10Gbe

[WALLEBROEK Bart]

We have a Windows Media server that has both a 1Gb and a 10Gb connection (only 
1 however is enabled at a time).
When running on the 1Gbe interface the backup speeds are normal.  All clients 
backup at speeds from 40 - 80 MB/sec.
When however disabling the 1Gbe and enabling the 10Gbe interface (same IP 
settings) all Solaris clients backup at speeds of 40-50 KB/sec, while Windows 
and HP_UX clients still backup at the previous mentioned speed (40-80 MB/sec).

Has anybody any idea ?  The 1Gbe interface goes to a different switch then the 
10Gbe fiber cable.

[Veritas-bu] Large site with Linux Master

[Dom]

Hi,

Just wanted to know if anyone out there has a large master with 1000+ clients, 
8000+ jobs a day, mixture of DBs, NDMP, OSs, mixture of storage like tape 
libraries and VTLs etc etc.

Just wanted to know what version you use, any issues or thoughts you'd like to 
share. Feel free to reply direct or to the group.

Thanks,

Dom

So I was having a conversation with one of the NBU product managers at Vision 
last week and I was told something I hadn't heard before.  Apparently the 
Sybase ASA database running behind Netbackup is now multithreaded and nbrb 
performance has improved.  In all the conversations and presentations around 
NBU7, this is the first time I had heard this and was a little surprised.  I 
would think they would be yelling this from the rooftops in celebration as 
resource broker performance has been a frustrating issue for many of us for 
years.

I'm just wondering if anyone else has heard this and if people are seeing real 
world gains after upgrading to 7 and if you can quantify it in some shape or 
form?  If this is true it's going to be a major motivator to start upgrading.

TIA

IMMEDIATELY remove the set of tapes and flip the write-protect tabs if you
haven't done so yet.. Then move the tapes to a non-scratch pool.

Once the tapes are in a non-scratch pool, you don't need to freeze them
because nobody will try and take them.  And write-protecting protects the
data and your butt at the same time.

[Veritas-bu] How to freeze an unassigned tape

[tim.lane]

Hi,

I have a set of tapes that contain an important backup.  The backup has 
expired, but the tapes haven't been over-written, and I intend to "bpimport" 
them at a future time.

In the meantime I want to freeze the tapes, but trying to freeze an unassigned 
tape produces the message "requested media id was not found in NB media 
database and/or MM volume database".

I thought I could assign the tapes with "vmquery -assignbyid  
   " and then do the freeze, but 
although the tapes get assigned (status 0 in "vmquery") they still can't be 
frozen.

Any suggestions?  (Solaris 5.9, NetBackup 5.1MP6, one master/media server, 
three further media servers all sharing the same drives with SSO).

Many thanks,
Tim Lane.

Re: [Veritas-bu] RedHat Ent 5 Kernal 2.6 on NBU 6.5

[WEAVER, Simon (external)]

Thanks Ed
There is nothing more to add really. A standard VM Box, with 8GB Ram, 4
CPU's and 1GB Network.
 
It used to take 30 Hours, so getting around 15 - 18 hours, I felt was
acceptable. Others seem to disagree.
 
I try to run the backups with "less" Network traffic possible (ie: When
other backups have run and kicking job off at 1am).
 
I do stream all the jobs to 1 tape though. There are 2 specific folders
that are causing the problem, and sadly, yes all Data to be backed up,
no exclusions. I have 5 folders listed under Backup Selection.
 
On the assumption that Streaming still works the same as other clients,
then I could try to break things down to multiple tapes. (ie: Maybe 1
large folder to drive1 and the other large folder to drive2).
 
Again, know very little about Linux, so its a little bit of blind
leading the blind. I did feel that for the Network speed, and spec of
the box, it was acceptable, especially when I have other systems that
have that much data on LTO2 technology taking 3 times as long !
 
Ho-Hum !

With a recent version of NBU, the default buffer sizes are typically

This is a standard client. Not dealt with Linux, so steep

Assume you a single Gigabit NIC.  Assume that you can get 70% throughput
on that NIC.  That means you'll top out at 70MB/sec.  You have
2,000,000MB to back up.  That's 28,571 seconds or 8 hours.  So that's
the absolute best you can ever hope for and that's assuming that you
have a master server that is doing no other traffic on that interface
and that your VM has no other traffic on its dedicated backup interface
- including backing up other VMs.

Now 70MB/sec is going to be next to impossible to get if you have lots
of small files.  Large files - perhaps, but small files - not a chance.
If you have lots of small files, the solution is the same as it would be
on Windows - use the snapshot client.


Without knowing a lot more about your environment, it's possible that
you're already doing as good as you're going to get.

I am also assuming that you've done the obvious and had a really good
look to see if you need to back that 2TB up at one shot or if you can
break it up into smaller pieces (or not do fulls at all by utilizing
synthetics or other approaches).

Jobs are being multiplexed and everything else seems to have finished 
apart from this client.

There are a few "db_lock_media: unable to lock media at offset 14 
(P843L2)" type messages for the first tape in use for the backups in 
bptm log

It successfully mounts the next tape it requires P805L2 (must have ran 
out of space on P843) and other jobs which were still multiplexing seem 
to write ok and finish.


Any other areas to look?

Yet on the Master the job is still active and says its about 90% through 
(although i don't use the gui a great deal).

Anyway on the gui job details it says it started loading a new tape 
P805L2 around 01:18 this morning???
There are also WRN messages from bperror on the master for the client in 
question with time stamps after 22:33.
The messages i have seen before and am not too concerned about, but how 
can the master still be doing things when the client bpbkar process has 
finished?

# bperror -all -client  -U  

--extract---

These messages keep repeating in the bprd log on the master every 10 odd 
minutes which i'm not sure if is related.:-

Jobs are being multiplexed and everything else seems to have finished 
apart from this client.

There are a few "db_lock_media: unable to lock media at offset 14 
(P843L2)" type messages for the first tape in use for the backups in 
bptm log

It successfully mounts the next tape it requires P805L2 (must have ran 
out of space on P843) and other jobs which were still multiplexing seem 
to write ok and finish.


Any other areas to look?

Re: [Veritas-bu] get back data from tape if fragment 1 deleted

[Michael Graff Andersen]

/usr/openv/netbackup/bin/tar -tMvb 128 -f /tmp/tapeid worked under NBU4.5
for listing the contains of a multiplexed backup
this command is for a block size of 64K.
