ABSTRACT:
A system for updating a data set through a geographical communication network. The data set is stored in a recovery storage unit located in a recovery data center and has to be updated with data blocks generated by a processing system located in a primary data center. The recovery data center is associated through the geographical communication network to a device provided with a temporary storage area for temporarily storing in corresponding storage locations the incoming data blocks generated by the processing system and directed to update the data set, wherein a first synchronous acknowledgement signal is provided to the primary data center acknowledging the successful writing in the temporary storage area of the data blocks as soon as the data blocks are written in the temporary storage area so as not to block or slow down the normal way of operating of the processing system, and wherein the locations of the temporary storage area occupied by the data blocks are made available for new incoming data blocks when a second acknowledgement signal is received acknowledging the successful updating of the data set.
