Not All Deduplication Methods Are Created Equal
What is Data Deduplication?
Data deduplication is a specialized data compression technique to eliminate duplicate copies of repeating data. This technology is particularly beneficial in virtualized infrastructure as it significantly reduces the required storage space caused by the redundancy of dozens or hundreds of virtual machines using the same or similar operating system. Its use can lead to significant cost savings and improved data management efficiency.
Deduplication works by segmenting data and identifying redundant segments while ensuring that only one unique data instance is retained and protected. When subsequent data is processed, the system references the unique data already stored instead of storing additional copies.
