Enum Constants

Name | Description
--- | ---
vssBackupContextAuto | This option lets the guest automatically select the right backup context among the values below.
vssBackupContextBackup | This correlates to {@code VSS_CTX_BACKUP}. It specifies that a shadow copy should be created by involving VSS writers to quiesce their respective application's data. A shadow copy created under this context has auto-release, non-persistent attributes: in other words, it is deleted upon the termination of a backup operation.
vssBackupContextFileShareBackup | This correlates to {@code VSS_CTX_FILE_SHARE_BACKUP}. It specifies that a shadow copy should be created without involving any VSS writer. A shadow copy created under this context has auto-release, non-persistent attributes: in other words, it is deleted upon the termination of a backup operation.
vssBackupContextUnknown | The value to be used when the older version client cannot recognize the enum value.
