The 7 Deadly Sins of Exchange Server Backups

Posted by Paul Cunningham on Dec 17, 2015 3:30:00 AM

A career-defining moment for many IT professionals is the day that their customer requests some data to be restored from backup, and the backup is found to be not working. Or even worse, the backup doesn’t even exist.

It’s not a situation you ever want to find yourself in, and to help you to avoid it I’m going to tell you about the common (but easily remedied) mistakes that can lead to such an unfortunate position.

Or, as I like to call them, the 7 Deadly Sins of Exchange Server Backups.


#1 – Not Taking Application-Aware Backups

Microsoft Exchange Server uses a transactional database system that is almost continuously in a state of change with a memory buffer, log files, and the database file itself all working together in unison to maintain the integrity and consistency of the mailbox data.

What this means for Exchange Server backups is that you can’t simply take a backup of the Exchange data by treating it as a bunch of files on a disk. Even though that may yield you a set of files on backup media, recovery from those files (without the risk of significant data loss) is impossible.

Microsoft only supports application-aware, VSS-based backups that properly handle the Exchange database engine and take a consistent backup of the database and transaction log files. If you aren’t sure, go and check that your chosen backup product is supported for Exchange Server backups.
