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.
"A wholesale replacement of file-level backup is likely for many organizations today, according to ESG research. For example, 55% of IT organizations surveyed by ESG plan to replace existing file-level backup with snapshot and/or CDP solutions. That said, the integration of snapshot, replication, CDP and deduplication into existing backup platforms to augment file-level approaches seems to be a strong trend. That's why several backup vendors have made recent strides to match capture techniques to recovery objective policies, simplifying implementations and optimizing the front end of backup processes.”
