Data Deduplication helps storage administrators reduce costs that are associated with duplicated data. Large datasets often have a lot of duplication, which increases the costs of storing the data. For example: User file shares may have many copies of the same or similar files.

Should I use deduplication?

Should you use it? Deduplication can drastically reduce the size of your data, but we recommend you store your database backups in a share without dedup. You might think that the amount of storage you save is worth it, and it might be.

What is the use of deduplication?

Data deduplication is a process that eliminates excessive copies of data and significantly decreases storage capacity requirements. Deduplication can be run as an inline process as the data is being written into the storage system and/or as a background process to eliminate duplicates after the data is written to disk.
