In this paper, the authors present YuruBackup, a space-efficient and highly scalable incremental backup system in the cloud. YuruBackup enables fine-grained data de-duplication with hierarchical partitioning to improve space efficiency to reduce bandwidth of both backup and restore processes, and storage costs. On the other hand, YuruBackup explores a highly scalable architecture for fingerprint servers that allow to add one or more fingerprint servers dynamically to cope with increasing clients. In this architecture, the fingerprint servers in a DB cluster are used for scaling writes of fingerprint catalog, while the slaves are used for scaling reads of finger-print catalog.
