Exchange……and the Vault

Anton LawrenceIT Services

What is the Enterprise Vault?

• Product created by Veritas but now owned by Symantec

• Currently on version 7

What does it do?• Archives material based on a set of policies

• Emails are moved from the Exchange store to a different backend

• But they are still accessible through the email client/web interface.

What can it do?

• Retain and delete emails based on policies

• Policies can be controlled around Active Directory Groups

• Public Folder Archiving

• Retrieve messages from pst files, scattered around the university

Initially we will not be utilising any of these.

Why vault?

• Exchange mailboxes are growing rapidy

• Mailbox sizes of greater than 300Mb are now not uncommon

• Some are even larger!

• Exchange has a limit of 2Gb per mailbox

• There are over 40 users with more than 2Gb of email in their Unix folders

• ITS want to introduce quota-less email

How the vault helps

• The vault moves messages away from your mailbox and onto a filer

• This can be done based on size or age…

• …of message

• Or the mailbox usage

• These messages no longer take up your quota

• And no longer take up space on our fast, expensive mail server disk

• They are indexed for easy searching.

Archiving Job

Archiving Job• If the message meets archiving criteria, then a

“stub” is created. This is an ordinary message that contains To, From, Subject, date information and instructions about what the message. Also an extract from the original email.

Accessing Archived Emails

• Emails can be accessed through the email client (Outlook is preferred). Tools can be installed.

• Double clicking on a message will retrieve it

• Clicking on the link will retrieve the message in a web browser

• Messages can be searched using tools within Outlook or based on the web

• Email can be accessed through OWA.

Manually Archiving Email

• “I want to archive some of my messages!”– You can do this through the use of Outlook and OWA
