摘要
对于企业数据的备份与恢复,文件级的细粒度快照提供了一种快速、灵活的解决方法。本文给出了Linux下VFS与底层文件系统之间的一个细粒度的通用快照层,在该快照层的基础上设计了一个低成本、高效率、可配置的远程容灾系统。
The fine-grained snapshot at the file level provides a fast and flexible solution to enterprises'data backup and recovery. This paper presents a fine-grained general snapshot layer between VFS and the underlying file systems in Linux, and designs a low-cost, high-performance and configurable remote disaster system based on the snapshot layer.
