As we are in phase to built a DR project for Enterprise Vault.We have some quries for the same...
1) Once the data is replicated to DR, is there any way in VCS to check for integrity of the replicated data?
2) Copying vault store partitions to new storage would be a time consuming task since the size of the partitions and the number of files is huge. What would be the best practice method recommended by Symantec for copying this data in order to improve efficiency and also minimize risk of data loss.
3) Once the solution is deployed, is it possible to revert back to windows format storage from Symantec format with minimal data loss?

ok ..
First thing, windows8 is not one of the supported operating systems, did you mean win 2008 server edition ? If yes, then win 2008 server is supported .. In VCS 6.0 Windows Server 2003 (x86 and x64) and Windows Server 2008 (x86) are NOT supported
Now To answer your questions :
1) Once the data is replicated to DR, is there any way in VCS to check for integrity of the replicated data?
--> This can be accomplished by using "vxrsync" utility. From VVR admin guide
The vxrsync utility allows you to synchronize or verify the data volumes on the source host with those on the target host. These data volumes could either be a set of volumes associated with an RVG or independent SFW volumes. This utility allows you to perform full synchronization or difference-based synchronization.
The set of volumes that you specify can either be a part of the RVG or may be separate volumes.However,it is important to note that when specifying volumes for the vxrsync operations the volumes must not be in use. The vxrsync utility with its synchronization and verify options can be used to complement VVR.
After performing either the synchronization or the data verification operation,the results are displayed in the current console from where the command is run.
The display is a progressive display and is shown on both the source and the target hosts. As the operation proceeds the status on the display console changes
Refer VVR admin guide here:
https://sort.symantec.com/documents/doc_details/sfha/6.0/Windows/ProductGuides/
you can also use vxrclient utility
vxrclient -verify -use <host> -with <host> -r<rvgname>
This command enables you to perform data verification between the source and target volumes.The RVG name is used as input to the command
2) Copying vault store partitions to new storage would be a time consuming task since the size of the partitions and the number of files is huge. What would be the best practice method recommended by Symantec for copying this data in order to improve efficiency and also minimize risk of data loss.
--> If possible, you can do first level sync by tapes or other storage media, with this you will only need to initiate differences based sync which will be quicker to a full resync if data is huge.
3) Once the solution is deployed, is it possible to revert back to windows format storage from Symantec format with minimal data loss?
--> what is the purpose here ? VVR will need to create RDS & SRL logs which can be associated with veritas volumes only.

Hi,
can you explain the setup a bit more ?
Are you using VVR to replicate the data ? what is the integration of VVR & VCS ? is it clustered using veritas GCO ?
what are the versions of OS & Veritas software in use ?

HI ,
Yes we are using VVR for replication the data.
Integration is not specify yet but we are planing to use GCO as we are looking out this setup for Enterprise Vault DR.
OS is window8 and latest verion of vcs with updated service pack.
