Exchange Backup Strategies

Overview Database files cannot be backed up while they are mounted, that is when they are online and serving requests. Instead Exchange provides an API for backup utilities to "Freeze" a database and write all new information to a temporary file. This type of backup is called online backup. Due to the nature of the Exchange database one can only backup the entire database using this process, not a single mailbox or a few selected items. On the other hand the Exchange server also writes all of the transactions to log files. This means that a properly configured Exchange server (that is the defaults are not changed) can easily recover from a database crash by replaying the log files on a previously backup up database.
