Exchange Server data (Mailboxes):

For Exchange Server data (Mailboxes): Use Incremental Backup. (Use the built-in Exchange Backup Agent to backup all the Mailboxes. Read the Client’s Help/Manual for more information. The agent does a full backup the first time it runs, and then backs up only new exchange emails (or tasks, contacts, etc) . There is no need to do a first full and then switch to Incremental. Just start out with Incremental backup for Exchange.)

For SQL Server (databases): Use BitBackup method. (Use the built-in SQL Backup Agent to backup all SQL databases. If you come across more than one instance of SQL Server installed on a system, you can backup the second instance as well by creating a new backup set for the second instance.)
