I'm running SQL 2008 R2. I have an intermediate issue with my backup for this one database. Some days the backup completes successfully with no problem and other days - could be 3 or 4 in a row - the backup fails with the following error:
Executed as user: NT AUTHORITY\SYSTEM. Cannot open backup device 'F:\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\SMS.BAK'. Operating system error 32(The process cannot access the file because it is being used by another process.). [SQLSTATE 42000] (Error 3201) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
The command used to backup the database is:
BACKUP DATABASE [SMS] TO DISK = N'F:\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\SMS.BAK' WITH NOFORMAT, INIT, NAME = N'SMS- Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10
Is there any way to determine what that process is that is preventing the backup from occurring? Or are there any suggestions on how I can ensure that the backup device isn't causing an issue with the backup?
Let me know if you have any questions.
Thanks in advance for your help.
