Thus, it was possible to compress a similar data backup at another point in time, which could take up an equivalent amount of space.ĭeduplication is different because it segments data and checks it against a matrix representing previously written data. However, compression savings only occurred at that point in time. During compression, backup solutions compressed data streams as the data was written to a backup tape or disk. However, its real distinction is data reduction against historical data, which allows storage savings and prevents copying similar data from multiple sources.Ĭompression was previously the primary storage savings activity before deduplication. From this definition, deduplication is not that different from compression. Therefore, data deduplication optimizes data storage to ensure the organization only copies and stores one unique data instance.Īt the basic level, deduplication eliminates non-unique data segments within data sets. Over time, it requires a significant amount of data storage. As a result, every software system data backup results in copying and storing large data sets. The data deduplication process eliminates redundant data copies and reduces a software system’s processing time. MSDP ensures cloud deduplication with compression and encryption, shorter backup times, and faster recovery at scale. As a result, Veritas has engineered NetBackup Media Server Deduplication Pool (MSDP) with over 80 patents specifically on deduplication. This complete guide on data deduplication explains all these and how Veritas builds advanced data deduplication technology into its NetBackup Appliance media servers. You need to consider issues such as the types of deduplication available, how the technology works, the factors affecting deduplication, how it differs from compression, and deduplication with virtualization environments. However, there are numerous elements to consider when picking the right backup deduplication technology for your business. It first appeared in 2003 when organizations wanted to move away from tape storage towards disk-based backups for their performance.Ī decade later, data deduplication is standard in backup products like Veritas’ NetBackup Appliances, making it a valuable tool in an enterprise data protection strategy. The technology has graduated from cutting-edge technology to a mainstream staple. As a result, the data storage becomes unnecessarily burdened over time with redundant data copies, which costs money as data requirements grow and processing times become slower.ĭata deduplication eliminates redundant data to reduce storage needs. They back up the data on auto-pilot, naturally resulting in continuous data re-coping and re-saving. Today, organizations save a lot of critical information in their databases daily.
