What is Data Duplication?
Data duplication is a technique that lowers storage overhead by getting rid of duplicate data. This techniques guarantee that on a storage medium, such disc, flash, or tape, only one distinct instance of data is kept. A pointer to the unique data copy is used in place of redundant data blocks. Data duplication and incremental backup are similar in that they copy just the data that has changed since the last backup.
What is Data Duplication?
Data duplication is a computational technique that removes multiple copies of data that repeat. If the method is successfully used, storage utilization may be increased, which might save capital cost because less storage media would be needed overall to fulfill storage capacity requirements.
