   Hi.. I'm trying to setup Flashbackup with Hardware Based Snapshot (EMC Snapview) but netbackup doesn't recognize EMC Clariion as snapshot method.. When I'm trying to run snapshot policy wizards on client NB says thay "No devices reside on disk arrays", but of course it's not true..
Snapshot created with EMC's standard command line utilities work perfectly.
What may cause problems in this situation ?

Marek-
I'm not very experienced with the FlashBackup option but I thought it required the Veritas File System underneath to function...?

My mistake it is Veritas Storage Foundations for Windows that I had read about.  Again not sure if it's required in your particular environment....just remembered reading that FlashBackup need VSF for Windows to work on Windows platforms.

FlashBackup works without VSF on Windows and it never was a requirement ..
I want to create snapshot on EMC Clariion which is supported in NB 6.5 but NB doesn't properly recognize snapshot methods for clients..

Hi, Take a look at this file : http://support.veritas.com/docs/279042

Are you trying the snapshot method for W2k3 (x64) called "FlashBackup Alternate Client" using EMC Clariion?

Yes, I want to configure this kind of backup, but I don't uderstand why it's supported only in x64 environment .. ???? Maybe it's a mistake in this document ?

If it's true, I should to manually create snapshot using command line utilities, mount disk to alternate client and perform flashbackup.

Firstly, to use the Snapshot/FlashBackup functionality as part of NetBackup, you need to license the NetBackup Enterprise Client (or Advanced Client in v6.0) for that client.

The combinations stated in the Snapshot client compatibility guide is the tested and supported configs by NetBackup engineering. It is by no means technically exhaustive. If you want a combination not inside, you need to contact your Symantec rep and give them some good business reason to get engineering to test and customize for that combination you require.

What you mention about using manual Navicli hardware snapshot and mounting it on the alternate host via script is another possible method that may be more suitable for your environment. However, note that you will potentally lose the VSS snapshot done to ensure a consistent snapshot.
