physical storage or external storage are the devices that use for storing informations . This includes Flash drives , DVDs , ROM and other external hard drives .They enable users to transfer data/information to other storage capabilities by using optical and magnetic technology. It empowers the end user to have an absolute control over the data stored on an external storage device. The media requires no software upgradation. Another important benefit of a physical storage media is that there are no downtimes experienced in these storage devices.

However, users can, at times, experience data duplication that results in corrupted files. In fact, in the advent of fire or any other disruptive event, companies run the risk of losing its critical business data. It is for this reason; companies are increasingly adopting cloud technology. This gives them greater scalability and more optimal use of their resources in a cost-effective way.

Cloud storage is significantly transforming the way companies store their mission critical business data. The systems are typically accessed through a web based user interface or via the Internet. It is an off-site storage space system managed by a professional third party service provider. A study conducted by EMC in 2012 revealed that the amount of data stored in virtualized environments by small and medium sized businesses (SMBs) have surpassed the information stored in the IT environment.

Cloud backup and storage solutions from a professional and well-established service provider are argued to be more economical in comparison to the conventional IT storage on-premise infrastructure. This is due to the following reasons:

  -  OpEx and CapEx: Pay as you go pricing model enables companies to only pay for the data stored. This trims-down their capital expenditure or CapEx, as well as operational expenditure or OpEx. This also helps them in scaling up & down based on their business requirements.

  -  Data storage Time: Companies having an in-house facility for data storage takes more time as compared to the ones who hire a third party service provider. This directly affects their overall operational and maintenance costs.

  -  Other Miscellaneous Costs: Besides the CapEx, OpEx, and TCO, there are other back-up and storage costs, which are difficult to quantify. This includes bandwidth, flexibility, reliability, agility, and performance .
