In this article on Tech Target, author Lauren Whitehouse examines why source deduplication and other data backup technologies are worth checking out. Although the focus has mostly been on target deduplication, source deduplication ensures that only changed segments are backed up after the initial full copy, significantly capturing, transferring and storing less data on disk.
