Hi,
I am using SQL Server 2005 standard SP3, doing a backup as follows:
BACKUP DATABASE db1
TO DISK = '\\whatever\DatabaseBackups\db1.BAK'
WITH INIT,
NAME ='Backup data of db1',
CHECKSUM

I am getting the following error:
BACKUP 'db1' detected an error on page (1:107675) in file 'D:\db1.MDF'.

dbcc checkdb is ok:
CHECKDB found 0 allocation errors and 0 consistency errors in database 'MyDb'.

DBCC execution completed. If DBCC printed error messages, contact your system administrator.

Did anyone encountered such a scenario and if so, what is the solution?

Yes it will, that's not what I asked.

Try the backup again, exactly as you did before.

Checksum failed for db1.mdf and you run checkdb for Mydb. I guess they both are same.

Are these the same? Or two different databases?

I guess 'UV' has solved his problem. It is more than 1 year old post.

The issue was solved by opening a ticket at MS support.
After a week or so they replied that it was identified as a bug within SQL Server and that it would be fixed in future versions.
