How to configure BCV backups using Netbackup 7.5

Hi All,

I am new to this forum and have started working on netbackup recently.

I need to configure Clone BCV backups using netbackup.

Please help.

Thanks in advance.

    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...

    Oracle control files cannot reside on disk areas being snapped/cloned.

    We are not using Snaphots for BCV backups rather recovery manager will generate the scripts automatically.

    recovery manager?

    As in Oracle Recovery Manager (rman)?  Using 'proxy' backup method?
    This still needs to integrate with EMC snapshot methods.

    Or something else that is called 'recovery manager'? 

    No idea how this can be done without snapshots or some sort of snapshot technology...

    My understanding of BCV (Business Continuity Volume) is that it is a mirror copy of the volume that resides on the source DB server and that the source server needs access to both volumes in order to write/sync both copies.
    To ensure that the BCV copy to be accessed and backed up by the media server is in a consistent state, a snapshot needs to be taken (    split/separate/activate or whatever it is called on the EMC side...)

    I only have experience with the snapshot methods explained in Snapshot Client manual.

    If you have other methods working for you - you are welcome to try it.

    Sorry for wasting both our valuable times....

    Do you mean EMC replication manager ? Don't think there is an integration between that and NetBackup

    At least there wasn't when I checked a couple of years ago.

    Replication manager is being used with EMC VNX snapview clone technology which will create the clones of databases and then Netbackup 7.0.1 on Solaris media server will work as offhost backup server and backup those clones to tape library and Datadomain.

    Can you plz suggest me short pointers to keep in mind while configuring all this setup ?

    So.. This is 'Replication manager'. Not 'Recovery Manager' as stated the other day....

    EMC VNX snapview clone is described in the Snapshot Client manual as stated in my lengthy post of the other day:

    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.

     

    In the 7.1 manual it is called 'EMC_CLARiiON_SnapView_Clone'.
