differential fails EVERY time right after successful full backup

Gossett
Level 6

the past two days I have done a full backup and they finish with not problems at all. All succesful verification, etc.. however, the next day I try to run a differential backup and get this exact error every time. I have tried to make sense of the support link but can't so here is the error:

I

The job failed with the following error: The Backup Exec SQL Agent was not used to create the last full, differential, or log backup of this database. You must use the SQL Agent to run a full backup before you can run a differential backup or transaction log backup.

 

If this is the case what exactly is backuping up my full SQL backups? this error doesn't make sense to me and i'm at a loss as I really am not in a positon at this moment for incrimental.  Any help is appriciated

Are you doing any SQL maintenance or backup jobs using SQL Server itself?  If so then these could reset the LSN resulting in your error.  See this document
