【摘要】In cloud computing environment, traditional backup technologies met the challenge of requiring agents, blank data recognition, high data redundancy and coarseness. For this reason, this paper studied a series of backup technology in cloud computing environment through vStorage APIs for Data Protection (VADP) interface, such as agent-free backup, block change tracking, file-level backup recovery, de-duplication, vCenter integration and application awareness. The effectiveness of de-duplication and block change tracking were shown, presenting a useful reference of data backup for cloud computing environments.%在云计算环境中，传统的备份技术遇到了需要安装备份代理、空白数据占用空间、数据冗余度高和备份颗粒度大等问题。基于此，研究了通过VADP接口，实现无代理备份、数据块修改跟踪、文件级备份恢复、重复数据删除、vCenter集成及应用感知等的云计算环境的备份软件技术，并验证了重复数据删除对数据块修改跟踪技术的有效性，为云计算环境的数据备份提供了有益的参考。
