Deduplication technology is essential to every company’s data backup process, especially when it comes to managing big data. It is designed to eliminate redundant data in a storage system, and reduce the amount of data that must be stored as a backup. When it comes to data security, deduplication is the fastest way to generate a return on investment because it enables an organization to decrease the amount of storage to buy and maintain.
Data deduplication also enables an organization to:
Can source dedupe or target dedupe from your backup application meet your needs? That will depend on your organization’s backup environment. Check out the descriptions of each type of deduplication below to decide which function is best suited for your organization.
As the name suggests, source deduplication occurs at the source or at the server or application layer. This type of deduplication is best suited to use at remote offices for backup to a central data centre or the cloud. It is also an ideal backup solution for environments with a low daily data change rate. Source deduplication is considered the slower of the two functions because it creates additional workload for the client device.
Benefits of source deduplication include:
Target deduplication takes place after the source has been backed up, at the target storage location. Since target deduplication provides faster performance for large data sets, it is typically used by large companies and fewer bandwidth constraints. Unlike source deduplication, target deduplication does is usually carried out with a hardware appliance.
Benefits of target deduplication include:
If your company is not already utilizing data de-duplication in your backup and recovery process, now is the time to consult a vendor that offers it as feature within their appliance.
