This issue has been solved. See solution.

Hi All.

Hope you guys are doing well :)

Master server version is 7.1

client version is 7.1

There is one mount point that i have to configure under Flash backup.

what i have to select in "Snapshot client option", whether auto or nbu_snap or vxFS-Snapshot

and what i have to select in "Backup selection" means when i was going through guide there what i see is below

Solaris examples:

/dev/rdsk/c1t0d0s6

/dev/vx/rdsk/volgrp1/vol1

and where i have to mention cache path and what is the cache path.

I read guide but still having above doubts.

Please help me out , its urgent..

Thanks in advNCE

Lets go back to the Snapshot Client manual for the answers:

p. 83:

UNIX only: if you selected nbu_snap or VxFS_Snapshot as the snapshot
method, specify a raw partition as cache, in either of these ways:
■ Use the Host Properties node of the Administration Console to specify
the default cache device path for snapshots. Click Host Properties >
Clients, select the client, then Actions>Properties, UNIXClient>Client
Settings.
■ Use the Snapshot Client Options dialog to specify the cache.
See “How to enter the cache” on page 149.
The partition to be used for the cache must exist on all clients that are
included in the policy.
 
If you go to p. 149, there is a bit more detail.
 
.....what is the cache path
As per above extract from the manual - it is a separate raw partition (preferably a separate small lun/volume) not used for anything else.
 
Please also read Sizing the cache partition on p. 147.

Hi Marianne.

Thanks much for the update.

But if i select AUTO in in "Snapshot client option", then there is a need of cache path?

And i have to mention MOUNT POINT PATH LIKE c0t0d0 in backup selection instead of mount point itself?

Please reply

Marianne's picture

You need to add the cache path SOMEWHERE!

Either in Host Properties or in Snapshot Client options.

You have to mention full path to raw device name in Backup Selection - /dev/rdsk/............
See the section that you found in the manual...

Hello Marianne.

How much cache size is required, total backup size is 750 Gb. Please revert

Marianne's picture

You REALLY need to read the manual... and follow advice given there.

I cannot tell you what the size of your cache partition must be.

Extract from my previous post:

Please also read Sizing the cache partition on p. 147. 

This section tells you HOW to determine size of cache partition.

Please select nbu_snap as snapshot method. (see manual for explanation)

Confirm that cache partition exists at OS level, that it is not mounted and that no filesystem exists on this device. (Confirm with 'fstyp /dev/rdsk/c#t#d#s# ' )

Create bpbkar and bpfis log folders on the client and retry the backup.

If backup still fails, copy client's bpfis log to bpfis.txt and post as File attachment.

Post policy config as well:
bppllist <policy-name> -L 
(must be big L, please)

Hello Marianne

Confirm all the things and select nbu_snap but still failing..

Want to know one thing that there is one Global Zone  and 4 local zone, and i want to take flash backup of local zone and as a cache path i select RAW path of Global Zone (because this raw path is for Global zone i.e. usnbuo5301c . Not for local Zone i.allianceqa)

Is this the issue?

wannawin's picture

Hello Marianne.

Can you please update on this..

Mark_Solutions's picture

Bank Holiday in SA I believe - be patient - sure Marianne will be along soon, even on a holiday!

Not totally sure flashbackup is supported on Solaris Zones but will await Mariannes update ...

Did you only realise today that you are working with zones? or simply thought it was not important enough to mention?

I have never tried FlashBackup on Solaris local zones and don't know if it is supported. 

This document contain details of NetBackup support for LDOMs and zones:
 
Unfotunately SymWise is down at the moment.
 
If it is supported, you will need to provide a raw partition in the local zone.
See this extract from my previous post: 
Confirm that cache partition exists at OS level, that it is not mounted and that no filesystem exists on this device. (Confirm with 'fstyp /dev/rdsk/c#t#d#s# ' )
What happens if you login to local zone and do 'ls -l <cache-device-path>'? 
or 'fstyp <cache-device-path>'?
 
**** EDIT ****
SymWise is back up.
 
Please see this extract from TECH162994:
 
Local zone support is limited to standard client, database agents, master server, media server and Bare Metal Restore client (as described in the Bare Metal Restore Administrators Guide).
 
 
This says to me that FlashBackup is not supported.

Thanks Mark!

Thanks much Marianne for update.

Is there any other alternate to take backup of this mount point, actually this mount point having millions of file.

Marianne's picture

Consider upgrading to NBU 7.5, implement MSDP and use Accelerator to backup this data.

Thanks for update Marianne.

Will talk with my manager on this and sugget for upgradation, will let you know..

Thanks much again

wannawin's picture

Hello Marianne.

Just to confirm once again.

This method(accelerator) is working for Local zone..?

Marianne's picture

I will have to look in documentation.... same as you.................

Maybe find a solution to this post, then start a new discussion asking:

"What is best backup solution for Solaris local zone with millions of small files?"

Hello Marianne/All

Not able to upgrade to 7.5(suggestion refused by senior management), is there any other alternative to backup this..

Thanks in Advance

Yasuhisa Ishikawa's picture

What I can only think wIthout FlashBackup, MSDP, and Accelerator is traditional way - devide backup target into multiple streams and take them simultaneously.
Do not make so much streams - this may cause high load on the client. Start with 4 or so streams.

I agree with Yasuhisa:

devide backup target into multiple streams and take them simultaneously.

Do something like this in Backup Selection:

NEW_STREAM
/mount/folder1 
/mount/folder2
/mount/folder3
/mount/folder4
NEW_STREAM
/mount/folder5
/mount/folder6
/mount/folder7
/mount/folder8
NEW_STREAM
/mount/folder9
......
NEW_STREAM
/mount/folder##
......

Select 'Allow Multiple Data Streams' in Policy Attributes and ensure 'Max Jobs per Client' in Master server Global Attributes is set to 4 or more.

** PS **
You will agree that this post is about configuration of FlashBackup and has been answered, right?
The discussion is now taklin a different direction that should be addressed in a separate discussion.

Please close this discussion and start a new one as per my suggestion on 21 March?

Hello Marianne/Yasuhisa

will start another discussion ..

but there is only single mount point that having millions of files to be backed up, how this happen?
