Abstract
Transferring data from a storage device to cloud service includes initiating a snapshot of the data, accessing each block of the data corresponding to the snapshot to transfer each block to the cloud service, and terminating the snapshot after all of the blocks have been transferred to the cloud service. At least some blocks of the storage device that are modified after initiating the snapshot may be copied from the storage device to a storage pool prior to modification. Only a first modification of a particular one of the blocks of the storage device may cause the particular one of the blocks to be copied to the storage pool. Accessing each block of the data may include accessing blocks of the storage pool. Modifying a particular one of the blocks of the storage device may include modifying a corresponding block of a storage pool.
