Hi Robert,

I recommend that you check the event logs and other system logs closely.
I think that there must be something else running (like another backup
type,
or a defrag, or something else) that is causing this situation to occur.
I know that you said that the exchange admin told you that the defrag
wasn't running within that timespan, but this error is the Exchange Server
telling you that expected log files are missing... and that you need
to run a full backup.

Thanks,

Del
