Re: Absolutely Bizarre - Backup reference database that doesn't exist
In Enterprise Manager, expand to Management > SQL Server Agent > Jobs, and look for your job that is backing up to your tape drive (you may also try under Management > Database Maintenance Plans).
Have a look in the Steps tab of this jobs Properties, and there should be a Step referring to model4IDR.ckp.
Alternatively, if your maintenance plan gets its instructions from a text file, find that text file and search it for references to your erroneous database.
I have the same error right now, but it's for databases that do exist. It turns out that when we had a crash the other week, the CD ROM was removed from my server, resulting in my secondary HDD moving from F:\ to E:\. Obviously the files for some of my existing databases cannot be found. It just shows that this error message usually means exactly what it says.
If you cannot find the file it is looking for, I suggest creating a text file of the same name and location (it couldn't hurt!!), and let it find that.
Lastly, that DB name looks TOO MUCH like the model db that all SQL Servers have, so exercise CAUTION. Cheers.
