Configuring an Exchange snapshot policy with Instant Recovery

Hi there,

we r facing a problem in configuring an Exchange snapshot policy with Instant Recovery 

our environment is clustered master server of NBU 7.5.0.4 on windows 2008 r2

i followed the TN 

http://www.symantec.com/business/support/index?page=content&id=HOWTO47317

 

and all its related TNs...but whenever i finish and click ok...this error pops up.

 

 

Any1 got what i am doing wrong in the configuration?

  • From the Nbu 7.5 Exchange Admin guide:

    NetBackup supports Instant Recovery backups with Exchange 2007 or later for non-clustered and non-replicated environments.

    The Instant Recovery and off-host options cannot be used with a replication or DAG backup.

     

    From the Nbu Snapshot Client Compatibility List, under
    VSS Snapshot Providers Support for Microsoft Windows >
    Exchange Comments >
    DAG snapshot compatibility in the table

    Recovery from local or off-host snapshot
    (I.e., Instant Recovery using software or hardware VSS providers)
    ...is not supported in a DAG environment.
    It will work if you are using standalone Exchange.

    Standalone Exchange selection lists do not have directives that begin with Microsoft Exchange Database Availability Groups:\.
    If a directive begins with that, then you cannot enable instant recovery.

     

    The TN:
    http://www.symantec.com/business/support/index?page=content&id=HOWTO47333#id-SF930596274

    ...is badly worded.

    This part in itself is correct, but not when Instant Recovery is involved:

    When you configure an Exchange snapshot backup policy, the only valid directives are: Microsoft Exchange Database Availability Groups:\ or Microsoft Information Store:\ (a database or storage group can be appended) .

    I guess it is just a case of bad placement of information.

  • I could confirm that EMC's Replication Manager does support SAN hardware VSS provider snapshots with Exchange DAG, but that would be outside of the scope of NetBackup and this discussion. It is not recommended that you have more than one backup solution for the servers if you are already using NetBackup.
    Things (Every)... could get complicated.
