症状
Using a Windows server that has an Oracle database that is installed on it where the default Oracle VSS Writer services are installed and enabled.
Using Oracle RMAN to create some local backup to disk, saving the backup generated files to a local directory. Whenever the file system backup is performed, it completes successfully. However, when logs are checked, it is clear that NetWorker has not backed up the oracle files.

原因
When a standard NetWorker file system backup is performed on this machine, all Oracle backup files are detected by the Oracle VSS Writer and gets added to a list that is then provided to NetWorker for backup. The NetWorker Client software does not support Oracle VSS Writer, a temporary directive to skip all files on the supplied list is generated automatically. As a result, all Oracle backup files are skipped without any warning to the NetWorker user. The backup is successful, but no Oracle backup files have been backed up.
解决方案
The current workaround for this issue is to perform the save operation with the "VSS:*=off" option or have Oracle VSS writer disabled or uninstalled. This can be set in the client properties through the NetWorker Management Console (NMC):

An official Request for Enhancement (reference RFE # NW-I-1965) isn raised with the Dell NetWorker Product Management team to request a warning system be implemented in future NetWorker versions, so that the skipped files are more easily detected by the user. Your Dell Site Account Manager or sales representative can track and link all RFEs.
