Backup deduplication, which reduces storage needs by eliminating redundant data, has moved from cutting-edge technology to mainstream staple. The data protection technology first showed up in 2003, aimed at organizations looking to move away from tape for the performance of disk-based backups. More than a decade later, dedupe is common in backup products, and can be a valuable instrument in data protection strategy.
But there are many elements to consider in picking the backup deduplication technology that fits best. How do zone-level and block-level deduplication compare? What are the differences between deduplication and compression? How important are deduplication ratios? What are the pros and cons of source and target deduplication?
