How to find the .DVS file name and location corresponding to an Enterprise Vault (EV) Archived item for EV versions 8 and higher. 

Note: For Enterprise Vault versions 2007 (7.5) and prior, see TECH48552.


Cause



Within EV 8.0, the storage model has changed.  Prior to EV 8.0, an archived item was contained within a single file with the DVS extension.  In EV 8.0 and above, the storage model changed to improve the Single Instance Storage (SIS) capability. This was performed by separating the item into multiple files (.DVS [header], .DVSSP [Shared part] and .DVSCC [converted content]). The DVS file in EV 8.0 and above is unique to the exact item as this contains the message header information only.  All other components (Attachments, message body, etc.) may be shared with other items. Regardless if the 'shared parts' (.DVSSP items) are present in other locations, the parent DVS file must be present for proper recombination of the item.


Solution



When an item cannot be retrieved via user or administration actions (Shortcuts or FSA Placeholder objects), it may be necessary to locate the corresponding parent DVS file to determine this is present on storage.

Note : For Microsoft Exchange archiving follow the steps below (Not applicable when Vault Store partition is located on EMC Centera or streamer device).

1.  Open Microsoft Outlook and select the archived item.

2.  Press CTRL + SHIFT and left-click any one of the EV toolbar buttons to open the EV Diagnostic window.

3.  Click the Vault Information button.  

4.  In the section titled Selected Item Properties, scroll down to the Saveset ID.  A character string should be displayed similar to:

         Saveset ID : 201007138983154~201006290011360000~Z~00FE32EB454E1765AC545E895FBE3821.
 
 
        1st Part   : 201007138983154 : Archived Date. (13-July-2010)
        2nd Part  : 201006290011360000 : Received Date (29-June-2010)
        4th Part   : 00FE32EB454E1765AC545E895FBE3821 : DVS File Name and IdTransaction.
 
The last number sequences correspond to the DVS file name located in the corresponding Vault Store Partition:
00FE32EB454E1765AC545E895FBE3821.DVS
 
In above Example
 
From the 1st Part : 201007138983154 of Saveset ID “20100713” search for folder “2010/07-13”
From the 4th Part : 00FE32EB454E1765AC545E895FBE3821 of Saveset ID "00FE" search for folder “0/0FE”
 
Hence the actual path for this item's “.DVS” file is “2010/07-13/0/0FE” and the “DVS” file name is “00FE32EB454E1765AC545E895FBE3821.DVS”.
