Email message are at the top of the list of the kind of data users wish to backup and protect. Yet these messages are also one of the more difficult types of data to backup. Let’s look at the challenges in backing up this type of data and then discuss how inSync does it.
Microsoft Outlook is one of the most widely used email clients. Outlook stores email messages in files known as PST files. Most of us have PST files that are a few GB in size, and it isn’t uncommon for them to be in the tens of GB. Traditional backup software, which simply identifies and stores these files, has the following limitations:
inSync differs from traditional enterprise backup software because it deals with individual email messages, rather than PST files. It relies on Messaging Application Programming Interface (MAPI) and queries specific attributes of messages in mailbox. These attributes are compared with a local reference and any new or changed messages are identified. New messages are backed up, as well as any attachments.
The use of MAPI gives inSync a number of advantages:
Beyond improving the backup process for email messages, this type of approach could make other email-related improvements possible. These could include the ability to restore individual messages, as well as e-Discovery capabilities for insight into message content. By making email data more manageable, MAPI offers possibilities for how that data can be used.
