Abstract

A local computing device replicates data stored in a cloud-based storage resource in a way that is substantially transparent to end users. A counter generation module provides a source for sequentially increasing counter indices, each of which is associated with a creation timestamp. When a data record managed by the cloud-based storage resource is created, updated or deleted, an address of the modified data record is recorded in a journal, along with unique counter index and timestamp values. Later, when data records stored in the cloud-based storage resource are to be replicated at the local computing device, data records corresponding to the sequential counter indices listed in the journal are sent to the local computing device. Only those data records which correspond to blocks of uninterrupted sequential counter indices are transmitted to the local computing device, thereby ensuring consistency of the replicated data.
