Backup Solutions for Exchange 2007

Solution 1:

Microsoft's DPM is an amazingly good backup tool. It does mail box level backups for Exchange. In addition to being able to backup files, SQL Server, and SharePoint. The SharePoint backup is better than EVERY other tool out there (right down to file level).

Solution 2:

A couple of free, hack-your-own solutions while waiting for the WSB Exchange plugin...

You can copy ntbackup.exe from a Win2003 box. I tested backup to disk with a restore, and it seems to work fine. Note that I you can't write direct to tape with it, or get brick level backups.

You can use PowerShell and diskshadow.exe to do an online VSS backup.

You can use ExMerge or Export-Mailbox to export out PSTs for brick level backup.

You can stop Exchange services, run a normal backup, and start Exchange for an offline solution.

All of these are disk based, so - for maximum recoverability - you'd want to copy offsite or to tape using your favorite tape writing software.
