What is data de-duplication?
De-duplication is one of the sophisticated ways that the YottaClient PC reduces the raw data from your network servers across all remote offices to a size that can be transmitted over the WAN. It ensures that the same data is never transmitted offsite more than twice, thereby saving the bandwidth to transmit only new or changed, unique data. It achieves this simple elimination by generating a digital signature by way of delta blocks as it is backed up and comparing it against the known details of all previous files. If the digital signature matches a previously backed up file, it must be a duplicate and only a shortcut need be transmitted up the line. Due to the way this technique is applied, it does not matter if the files are on different servers, at different offices or even have different filenames.
