Abstract: Cloud storage acts as a cloud computing model, where the data is stored on the remote servers that could be accessed over the internet or the cloud. The cloud storage is completely operated and maintained by several Cloud Storage Service Providers (CSSPs). The CSSPs use storage servers for storing huge data in cloud. These servers are constructed by applying several virtualization techniques. There have been more contradictions on the terms ‘Cloud Storage’ and ‘Cloud Backup’. A cloud storage server only stores the files in the cloud and maintains the data as long as it is retrieved again for future use. As the size of the data grows, the complexity within it also increases. The expectation arises on the ability to make the data available constantly without any interruption. In such cases, we need to adopt more advanced sophisticated backup strategies, by making use of the cloud services to deliver consistent back-up solutions to the users and the organizations and also provide quick disaster-recovery solutions. In this paper, we discuss about the secure storage of data and analyse possible solutions on secure storage of backup data in the cloud.
