SYMPTOMS

You create a compressed backup for a database in Microsoft SQL Server 2008. Then, the operation stops responding. However, you find that you cannot stop the backup process. If you examine the problematic process by running the EXEC sp_who2 command, you find that the process has the rollback status.

This issue is most likely to occur if the following conditions are true:
  • The I/O from the instance of SQL Server to the backup device is very slow.
  • There are many backup memory buffers.

CAUSE

This issue occurs because I/O buffers and the threads for the backup process are not always stopped correctly when the compressed backup operation is aborted.
