DEDUPLICATION THROUGH VIRTUALISATION

Is your current Data storage & backup system saving space and simplifying the managing of data chunks?

Migrating to a cloud infrastructure is not enough for an enterprise to get the maximum out of virtualization. As the volume of data increases so does the need to reduce data redundancy. Thus, data Deduplication has become inevitable making it almost a standard component of all modern data backup systems. Data Deduplication used in back up methods helps to make data storage more efficient resulting in more storage and network bandwidth. Reduction of network burden is another benefit of Data Deduplication by allowing backups on the disk

The entire process of making provision of hardware and software services as ‘Utility on Demand’ is achieved by interconnecting Virtualised Computers. In such a virtualized environment, many ‘Virtual Machines’ (VM) can be created in the Cloud. 

The ‘copying and storing’ the VM image and moving one VM image from source host to target without suspending the source enables Live Virtual Machine Migration. It is in here that, migrating of entire information from source machine to target machine requires utilization of high bandwidth which calls for deduplicating the redundant data before migration.

Such process of Deduplication is achieved with the help of three main steps - chunking, fingerprinting, and indexing of fingerprints.

There are few techniques which are followed in achieving Deduplication depending on certain criteria namely –

1.    Based on what type of Data Deduplicated there are two methods in Deduplication –

a)    File Level Deduplication

b)    Block or Subfile Deduplication:

2.    Based on implementation methods there are two methods in Deduplication –

a)    Source/Client based Deduplication

b)    Target based Deduplication

3.    Based on how Deduplication is done, there are two methods.

a)    Hash based Deduplication

b)    Content or Application-aware Deduplication

Beside these above mentioned, there are some other equally popular techniques followed in Data Deduplication, namely –

     I.        Extreme Binning:

    II.        MAD2

  III.        Cloud Spider

  IV.        Optimization of Deduplication Technique

   V.        Multi-level Selective Deduplication

  VI.        SAFE: Structure-Aware File and Email Deduplication

 VII.        On-Protocol-Independent Data Redundancy Elimination

VIII.        Liquid

 Thus, Deduplication is key for back up services, wired network, wireless, cellular network, so on and so forth in order to reduce the amount of data in storage and to speed up the backup process. All these techniques mentioned above use the same 3 Step approach to achieve data Deduplication . For additional information, please do reach out to us on [email protected] .
