flashbackup unix

[rookie11]

I was give to work on flashbackup unix,,, no previous exp. so far  
confusion is about their selection list don't know what they are backing up.
2 policies on NBU 6.5

1 flashbackup unix[solaris]  ---- failing daily  ,2 unix snapshot [solaris] -- running fine

backup selection list unix snapshot [solaris]

METHOD=USER_DEFINED

DB_BEGIN_BACKUP_CMD=/appl/iwov/iw-home/bin/iwfreeze +360

DB_END_BACKUP_CMD=/appl/iwov/iw-home/bin/iwfreeze --

/appl/iwmnt

backup selection list flashbackup unix  [solaris

DB_END_BACKUP_CMD=/appl/iwov/iw-home/bin/iwfreeze --

/dev/vx/dsk/appldg/vol03

can anytelll from backup selection list what they are backing up

[Marianne]

Extract from Snapshot Client Admin Guide:

Configuring backup scripts

Add the following directive to the start of the Backup Selections list:
METHOD=USER_DEFINED

Add one or both of the following directive(s), as required.
DB_BEGIN_BACKUP_CMD=your_begin_script_path
DB_END_BACKUP_CMD=your_end_script_path

The backup selection in your policies are :
/appl/iwmnt

/dev/vx/dsk/appldg/vol03

Replace these backup selections with the RAW device names. Extract from Snapshot Client manual (note the rdsk):

Solaris examples:
/dev/rdsk/c1t0d0s6
/dev/vx/rdsk/volgrp1/vol1

HP examples:
/dev/rdsk/c1t0d0
/dev/vx/rdsk/volgrp1/vol1

iwov is short for Interwoven, a company that provides contents management software. My guess updates of the CMS is suspended while the backup is running and then enabled after backup has completed. And since a CMS can contain many small files, Flashbackup is a good choice.

Hi ALL,

I am facing a problem with this kind of flash backup.
The Bakcups are failing with EC 156.

any suggestion experts

[Marianne · Accepted solution]

Suggestion: Have a look at the Snapshot Client Admin Guide - read the Flashbackup chapter and read through the snapshot options.
Selecting vxvm assumes the following (extract from manual, p.63):
the client’s data is contained in VxVM volumes that were configured with one or more snapshot mirrors.
FlashSnap license is also needed (p. 71)
Is this the case? If not you need to dedicate a small raw partition (+- 5% of data volume) as cache partition for snapshot.
The snapshot methot will then be nbu_snap or vxfs (if this is a vxfs filesystem).
p. 121:
How to enter the cache
For the nbu_snap and VxFS_Snapshot methods, you must identify a raw partition that the copy-on-write process uses, in any of the following ways.
■ You can specify the raw partition when using the Snapshot Policy Configuration wizard to create a Snapshot Client policy.
■ If manually selecting the snapshot method on the Snapshot Client Options dialog, you have two options for specifying the raw cache partition:
■ Under Host Properties > Clients > Client Properties dialog > UNIX Client > Client Settings: specify the raw partition in the Default cache device path for snapshots field. For example: /dev/rdsk/c1t0d0s6. This setting applies to the client in all policies.
■ Or, under Policies > Attributes > Snapshot Client Options dialog, specify the raw partition in the Cache device path, Value field. This cache setting applies to all clients in the current policy, and overrides the cache setting in the Client Settings dialog.
■ If you want NetBackup to select the nbu_snap or VxFS_Snapshot methods by means of the auto method, specify the cache as follows: on the Host Properties > Clients > Client Properties dialog > UNIX Client > Client Settings.
