Abstract
The present invention provides a way to use flash memory to keep backup copies of the recently modified data. The recently modified data is stored on a local hard drive and replicated (usually with versions) on a local flash drive when the network connectivity does not exist or not sufficient. As soon as the network connectivity is established the accumulated data is sent to the remote CDP server and the whole space of the flash drive can be reused again. As a result, the data is always replicated: one data copy is stored on the hard drive and the other copy is stored (usually with versions) either on a remote server or a local flash drive. Therefore, the combination of the data on the CDP server and the flash drive can be used to reconstruct the data stored on the hard drive.
