For most businesses today, e-mail is the preferable communications tool that allows their people to communicate with each other and share much information.
Each user Mailbox is stored on the Exchange Server Mailbox Database. So, it is necessary to backup the Exchange Database regularly. Mailbox server backups are the most important of all Exchange Server 2010 roles, in an organization. Although, in Exchange Server 2010, deploying a Database Availability Group reduces this risk, somewhat due to the replication of data between multiple servers. It is always recommended to backup databases anyway. However, as a general statement, without the backup of databases there is a risk of critical email and public folder information being lost in a disaster. This makes the databases, another, if not the most important part of your Exchange Server 2010 backup strategy.
