用于OpenVMS操作系统的Spiral文件系统采用了一种新的技术方法来备份数据。快速、低影响的备份可用于在应用程序主动修改数据时创建文件系统的一致拷贝。Spiritual备份使用日志结构的文件系统来解决备份问题。物理磁盘结构允许以接近最大的设备吞吐量保存数据，而很少处理数据。备份系统可以在不影响增量备份或快速选择性恢复等功能的情况下实现此级别的性能。
The Spiralog file system for the OpenVMS operating system incorporates a new technical approach to backing up data. The fast, low-impact backup can be used to create consistent copies of the file system while applications are actively modifying data. The Spiralog backup uses the log-structured file system to solve the backup problem. The physical on-disk structure allows data to be saved at near-maximum device throughput with little processing of data. The backup system achieves this level of performance without compromising functionality such as incremental backup or fast, selective restore.
