VSS_COMPONENT_FLAGS enumeration (vswriter.h)

  • Article

The VSS_COMPONENT_FLAGS enumeration is used by writers to indicate support for auto-recovery. These values are used in the dwComponentFlags member of the VSS_COMPONENTINFO structure and the dwComponentFlags parameter of the IVssCreateWriterMetadata::AddComponent method.

Syntax

typedef enum VSS_COMPONENT_FLAGS {
  VSS_CF_BACKUP_RECOVERY = 0x00000001,
  VSS_CF_APP_ROLLBACK_RECOVERY = 0x00000002,
  VSS_CF_NOT_SYSTEM_STATE = 0x00000004
} ;
