Enabling Enhanced Incremental Backup: Documentation Issue do ver 8/9 still use 6's setup procedures?

Current setup:  Data Protector 8.13,  2003 Server MSCS Cluster File Shares being backed up.

 

There are enhanced incrementals running on the clustered file shares.  From what I can find, it was setup according to  "HP Data Protector 6.0 software object consolidation Best Practices" paper.  (4AA1-8956ENW.pdf or c01425312.pdf neither of which I could find on the internet but did tucked away in an archive of saved files)  My office started using Data Protector around version 6.  

 

I'm currently replacing the 2003 MSCS with Server 2012R2 MSCS Cluster File Shares and looking to maintain the implementation of our enhanced incr backups.  

 

I can't find any Documentation for Version 8 that references this issue.  The closest thread I can find related to my issue is  __here__  and turns out to be from the second guy before me to manage the backups for my office.

 

Question:  Anyone know if the 6.0 document is still the way to go or if DP 8/9 manage MSCS Cluster File Shares differently?

 

For reference here's the section from the "Best Practices" document:

 

Enabling Enhanced Incremental Backup in a Cluster Environment pg. 20-21

 

For backing up shared volumes inside a cluster environment, a volume can be backed up from any (physical) cluster system. This requires that the incremental local database for each shared volume is always available on that physical system where it is currently mounted. This can not be guaranteed in case the enhanced incremental database is stored inside the HP Data Protector Software home directory.

 

In order to solve this issue, the enhanced incremental database is moved to the shared volume and appropriate links pointing to this shared volume are created on all cluster nodes.

 

The following steps have to be performed before the first enhanced incremental backup is performed:

 

Create a repository directory and links as described below:

 

Microsoft Cluster Server

1. On the shared mount point that will be backed up, create the following directory:
   mkdir <drive letter of the shared volume>:\enhincrdb
   mkdir <drive letter of the shared volume >:\enhincrdb\<drive letter of the shared volume >

Example: drive letter = F
   F:\enhincrdb
   F:\enhincrdb\F
2. On each node, create a link to the enhanced incremental database by running:
   linkd “C:\Program Files\OmniBack\enhincrdb\< drive letter of the shared volume>” “<drive letter of the shared        

   volume >: \enhincrrep\< drive letter of the shared volume >

Example: drive letter = F
   linkd “C:\Program Files\OmniBack\enhincrdb\F” “F:\enhincrdb\F”

 

The linkd.exe utility is available in the Windows resource kit.

 

Now you can perform backups of data on this mount point in the enhanced mode.

 

UNIX
1. On the shared mount point that will be backed up, create the following directory:
   mkdir /<name of the shared mount point>/enhincrdb
   mkdir /<name of the shared mount point>/enhincrdb/_<name of the shared mount point>

Example: name of the shared mount point = shared_disk
   mkdir /shared_disk /enhincrdb
   mkdir /shared_disk /enhincrdb/_shared_disk

2. On each node, create a link to the enhanced incremental database by running:
   ln –s /<name of the shared mount point>/enhincrdb/_<name of the shared mount point>  

   /var/opt/omni/enhincrdb/_<name of the shared mount point>

Example: name of the shared mount point = shared_disk
   ln -s /shared_disk/enhincrdb/_shared_disk /var/opt/omni/enhincrdb/_shared_disk

Now you can perform backups of data on this mount point in the enhanced mode.

    Hi,

     

    Similar can be found in DP 8 and 9 “Help” that comes with installation (press F1 from GUI). Details can be found under topics:

    Microsoft Cluster Server

    Create a repository directory and links as described below. The mount point directory (MountPointDir) is obtained from the mount pointThe access point in a directory structure for a disk or logical volume, for example /opt or d:. On UNIX systems, the mount points are displayed using the bdf or df command. by replacing any ":" (colon) and "\" (backslash) characters with the "_" (underscore) characters, and omitting the trailing ":" or "\".

    Steps

    1. On the shared mount point that will be backed up, create the following directory:

    enhincrrep

    For example, if your shared mount point is F:, create the following directory structure:

    F:\enhincrrep

    1. On each node, create a link to the enhanced incremental database by running:

    linkd Data_Protector_homeA reference to the directory containing Data Protector program files (on Windows Vista, Windows 7, Windows 8, Windows Server 2008, and Windows Server 2012) or the directory containing Data Protector program files and data files (on other Windows operating systems). Its default path is %ProgramFiles%\OmniBack, but the path can be changed in the Data Protector Setup Wizard at installation time. See also Data_Protector_program_data.\enhincrdb\MountPointDirMountPoint\enhincrrep

    For example, if your shared mount point is F:, run:

    linkd Data_Protector_home\enhincrdb\F F:\enhincrrep

    The linkd.exe utility is available in the Windows resource kit.
