I am getting the above error when tring to backup to a device on the local machine.  I can backup to another device located in the same directory. I have checked the permissions and have Full Control.  These worked before I went on vacation but now fail.  I can get around the problem by setting up all my backups to write to a new device but don't really want to do this. Help !

Please check out if the NTAccount the SQL service(s) run do have the permissions...

Hi,

The description of the Error is as follows.

Can't open dump device '%.*s', device error or device off line. Please consult the SQL Server error log for more details.

Have you tried looking in the Error Log.

Cheers,

T.

1. I think the sysdevices is not having the proper entry of that device file. Better run the DBCC on Master  database and try to backup .

2. Create a new device and using sp_addumpdevice try to just add that file to the new device you created.

Get back to me immed. still you have any problem

Hi,

If you have access to Books On Line you can check the correct Syntax for it there.

eg.

DDBC CHECKALLOC [(database_name [, NOINDEX])]

DBCC is used to check the logical and physical consistency of a database, check memory usage, decrease the size of a database, check performance statistics, and so on. DBCC is the SQL Server "database consistency checker."

OOPS - Should have read DBCC of course.
