How to configure BCV backups using Netbackup 7.5

No need to create scripts when Snapshot Client is configured.
The backup policy will automate the entire process.

The key is to test the process manually to ensure all required components are in place.
Media server and client where source volumes exist should be the same NBU version.
Prior to NBU 7.0 agents and options (incl Snapshot Client) had to be installed separately.)

The 7.0 Snapshot Client Admin Guide can be found here: http://www.symantec.com/docs/TECH127074

Chapter 1 is important as it explains how NBU snapshots work with the different snapshot technologies as well as requirements.
You will concentrate on all parts that reference 'disk array snapshot methods'.

Chapter 2 explains installation (and that the Snapshot Client binaries are included in server and client software as from NBU 7.0) and licensing requirements.

Chapter 3 explains policy creation.
Read through this chapter, but before actually configuring the policy, ensure that all components are in place and that all steps can be manually executed.

Off-host backup must be selected and media server specified as Alternate Client.
Under Advanced options you need to select the correct snapshot method.
You need to go to disk array methods on page 166.
Find the correct EMC snapshot method.

Jump to chapter 10: Configuration of snapshot methods for disk arrays
Read the information section and then
Tasks for the array administrator
and
Tasks for the NetBackup administrator

Have a look at the config diagram and ensure that array snapshot software is installed on the source client and the media server.
Go through the EMC-specific section for configuration steps.
(Ignore VSS sections for Windows).

Here is where you need to test the process manually.
Important to put Oracle dbs in backup mode before the snapshot is taken on source client.

Easiest way to test a policy is to first of all do a normal volume/filesystem backup with snapshot taken after Oracle dbs was put in backup mode.
Go back to policy section -> Configuring backup scripts
4 Add the following directive to the start of the Backup Selections list:
METHOD=USER_DEFINED
5 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

These scripts will be the scripts on the source client that will put the dbs in backup mode and to end backup mode.
The volume name(s) in Backup Selection following the script names must be the source volumes on the source client.

In Clients tab you specify the source client name.

Once this is working, you may want to attempt Oracle agent backup...
But lets keep this for a new discussion once you get a volume-level backup to work...
