The existing bacula Exchange plugin uses the esebcli2.dll api, which is
not supported under Exchange 2010. Exchange 2010 can only use VSS to do
backups, and while Bacula supports VSS in the bacula.org edition, it
doesn't involve the writers in the backup so you effectively only get a
'crash consistent' backup, rather than all the bells and whistles of the
VSS writers like transaction log flushing etc.

So you either need to do the backup another way to a file, or use
circular logging, making sure you understand what circular logging takes
away from you in terms of exposure to crashes etc.
