In this paper we describe Cumulus, a system for efficiently implementing filesystem system backups over the Internet. Cumulus is specifically designed under a thin cloud assumption--that the remote datacenter storing the backups does not provide any special backup services, but only provides a least-common-denominator storage interface (i.e., get and put of complete files). While Cumulus can thus use virtually any storage service, we show that it still provides efficiencies comparable to integrated approaches.
