To address the problem of vast amount of duplicate data in the file backup server,a deduplication-based file backup system is proposed,which has the capability of providing service for multiple users located anywhere.It eliminates not only the duplication data inside the single user,but also the duplication data among multiple users.Through this method,the storage space of backup server is economized further.Simultaneously,some security measures are applied to preventing data loss and user information leakiness.At last,the experiments show the viability of the system which provides a new solution of centralized backup for multiuser.
