I have Backup Exec 2012 SP3 running on Windows Server 2008 R2 backing up a Microsoft Exchange 2007 server on a D2D2T backup plan with weekly full and daily incremental backups to deduplication store and linked copy jobs to a LTO tape library. Yesterday I modified the job and took care to run the full backup manually to avoid Backup Exec's complaint about changed job settings on the incremental job. That full backup completed successfully. Today I find the nightly incremental job has failed with the error:
V-79-57344-862 - Backup Exec Agent for Microsoft Exchange wurde nicht verwendet, um das letzte vollständige Backup dieser Datenbank zu erstellen. Führen Sie ein vollständiges Backup mit Exchange Agent aus, bevor Sie ein Differenzial- oder inkrementelles Backup ausführen.
(Backup Exec Agent for Microsoft Exchange wasn't used to produce the last full backup of this database. Perform a full backup with Exchange Agent before you perform a differential or incremental backup.)
Me: "Huh? But I just did!"
What might have caused that error and what should I do to fix it?
Thanks,
Tilman
