In today’s world more than five billion Gigabytes of data is generated every ten minutes. Managing and protection of the tremendous data becomes major concern as data can be lost because of hardware failure, man made mistakes or unpredictable nature. Protection of data requires taking backup and in order to take backup various traditional technologies such as disks, tapes, optical media, NAS, DAS and virtualization is used. Major drawbacks of traditional technologies are hardware failures, requirement of more storage space and security. Hence new technologies such as storage virtualization provides efficient in storage space, less time for backing up data and more security. This paper explains the survey of different technologies used for backing up data on storage.
