Recovery of data or data backup is nothing but accessing the data that is being lost or corrupted by other means of recovery if one cannot retrieve it in normal ways. However data backup has two distinct purposes, one refers to retrieving lost or deleted data whereas the other refers to having a pre-decided and designed data retention policy which would save data from any sorts of unexpected disasters. Whereas data recovery refers to a process through which one can retrieve inaccessible data by using any of the available secondary storage mediums. The data recovery or data backup systems protect one from any unexpected or unpredictable loss of data. The data backup process works with data retention - a policy which is being pre- devised by the user. Under data backup system generates a carbon copy of all data and each process which enlarges the data storage requirements. Due to its unprecedented storage requirements, data repository systems have to be designed that would provide data security and portability. The data recovery process involves retrieving data from any of the secondary storage mediums if it cannot be retrieved in a normal way. The need for data recovery arises when there is either an operating system failure or a drive-level failure. When either the failures occur we use any of the available recovery solutions such as, partition table or master boot system whichever is compatible with the situation. Both data backup and data recovery possess certain set of sequential steps to be followed before devising a plan of recovery or backup. The steps involve, 1.	Data to be recovered 2.	Methods of recovery or backup to be used 3.	When to run backups or recovery systems? 4.	Secondary media to be used for recovery or backup 5.	Storage of backup or recovery files The extensive use and need for data recovery and backup solutions have enlarged scope of data recovery and backup soft wares. Certain iconic software and hardware developing companies are providing data backup and recovery solutions to many companies who are in need around the world. Software is being developed to enhance the efficiency of the whole system of data backup and data recovery that would control and protect the data at each and every stage of the process. The whole system of backup and recovery works on a single principle of protecting the data in case of miscreants or unforeseen.&nbsp;
