Message Stub Management and Rehydration
One of the many benefits Enterprise Vault provides is the ability to manage Exchange email box sizes by moving an email message and/or attachment from the user’s Exchange mailbox to the archive while keeping them accessible to end-users by placing a pointer (or stub) in the user’s mailbox pointing at the archived email message/attachment in the Enterprise Vault archive. With emails and their attachments making up the vast majority of data stored on the Exchange server, stubbing reduces the size of the email store producing a higher performance, more reliable email messaging system - without end user compromises.
Over time this stubbing capability creates hundreds of thousands or millions of stubs within Exchange pointing at messages in the Enterprise Vault email archive. In most cases the end-users cannot tell which mailbox line items are stubs and which ones are “whole” messages. When it comes time to migrate your Enterprise Vault archive, this stubbing capability creates several problems:
- If the archive is migrated to any place other than the Exchange server containing the message stubs, those millions of stubs won’t work anymore and end up generating error messages - dramatically impacting end-user productivity.
- Exchange does not have an easy way for Administrators to find and delete those orphaned message stubs.
- Message stubs can include additional metadata generated from their movement from folder to folder within Exchange. This additional metadata could be discovered in certain legal cases so should not be arbitrarily deleted.
- Systematically matching up individual message stubs with the archived messages in a forensically sound process is extremely difficult and time consuming.
Archive 2-Anywhere is the only mail archive migration solution that can systematically find and restore stubs with original messages, and remove leftover stubs from the Exchange server in a forensically sound process.
