Reduce costs with Deduplication

Nowadays, the economic situation globally is not quite stable. Enterprises are looking for ways to reduce costs and increase efficiency – optimization technologies are considered to be the most important and significant. Enterprise industries are facing a two-sided challenge: store and manage increasing amounts of data while simultaneously reducing the carbon footprint — they are required to do this in a way that enables them to meet recovery requirements. Deduplication is a technique that can dramatically improve storage system performance, minimize capacity requirements, and speed up data recovery. The deduplication can be done on source or target levels. While source deduplication shrinks backup windows and minimizes backup bandwidth, the target deduplication minimizes software deployment time, risk, and disruption and maintains backup software flexibility.

One of the solutions is EMC Data Domain. Data Domain offers a matured target deduplication solution. Technically this is an appliance which receives backup data, performs real time deduplication (recognizes data blocks which already reside in the repository and prevents rewriting them) and writes to internal disk system. Because the fact that backup data is very repetitive (especially full backups) the deduplication ratio can be very high (1:10 and higher).

Every appliance can be connected via Ethernet (NFS, CIFS, OST protocols) or FC (VTL). The CPU performs inline checksum, comparison, compression and prefetching. The data is arranged in containers in an optimized dedicated filesystem and written on internal SATA drives.

For DR purpose there is a replication mechanism which replicates deduped data to another appliance. This lowers WAN costs and improves SLAs. The replication can be arranged as many to one, thus consolidating backups from many branches or different data centers.

The whole line of Data Domain appliances ranges from several terabytes of backed up data to petabytes and this covers needs of most enterprises.
