Abstract: This paper considers disk as the storage media instead of tape for network backup system and studies how to restore data efficiently via snapshot, incremental transferring and fast hitting target data etc based on disk-based backup solution. It presents a working system called “A-Backup System” that offers new benefits such as efficient data restoration and incremental backup, querying data backed up, no administrator’s care as well for disk-based network backup systems, benefits not possible before with tape-based backup systems.

摘要： 使用磁盘来替代磁带作为备份系统的存储介质,并且研究通过快照技术、增量传输、快速定位目标数据等技术来实现快速高效的数据恢复。实现了集成这些技术的原型系统A-Backup,在该系统中不仅实现了快速恢复数据,还具备以往磁带备份系统所没有的特性,如增量备份、可以查询已备份数据、无须管理员值守等。
