IMSAdminBase::EnumBackups

  • Статья

The IMSAdminBase::EnumBackups method enumerates the metabase backups in a specified backup location, or in all backup locations. Repeated calls to this method, increasing dwMDEnumIndex from 0, will return information for each metabase backup in the backup location until HRESULT_FROM_WIN32 (HRESULT_FROM_WIN32(ERROR_NO_MORE_ITEMS)) is returned.

HRESULT EnumBackups(
      LPWSTR pszMDBackupLocation,
      DWORD __RPC_FAR* pdwMDVersion,
      PFILETIME pftMDBackupTime,
      DWORD dwMDEnumIndex
);

Parameters

  • pszMDBackupLocation
    On input, a buffer of length MD_BACKUP_MAX_LEN times sizeof(WChar) containing an empty string or a string of up to MD_BACKUP_MAX_LEN Unicode characters that identifies the backup location. If an empty string is input, the method will enumerate backups in all backup locations, returning the backup location in this parameter. If a backup location is specified on input, only backups in the specified backup location will be enumerated.

  • pdwMDVersion
    Receives the version number of the backup.

  • pftMDBackupTime
    Receives the date and time of the backup, in Universal Time Coordinate (UTC), formerly GMT (Greenwich Mean Time).

  • dwMDEnumIndex
    Specifies the index number of the backup to be enumerated.
