Abstract: Cloud Computing is a technology that offers many services through Internet and remote servers. Data storage is one amongst its services. Storing voluminous data generated as a part of day to day business activities requires loads of storage resources and is costly affair to own these storage devices. A better solution to this is Cloud Storage. Data stored in cloud is made available as a service through a network. Cloud offers data access irrespective of the user or data location with minimal efforts. This flexibility has attracted many users towards cloud storage services. Data gets transmitted through internet and users can access data regardless of their location or access device. It is the combined responsibility of the user as well as the Cloud Service Provider(CSP) to safeguard data on the cloud. Service Level Agreement(SLA) is a contract between the provider and the user that contains the terms and duration of service offered by the cloud provider. During the service period, Multiple copies of data is backed up at different geographical locations for data availability and every trace of data may not be completely destroyed on expiry of SLA. Even after deletion of user’s data from cloud there may be some data which is not visible to the user but may be present on servers. This is referred as Data Remanence. When a file is deleted the Operating System(OS) will remove the file entry in the file system but data will exist on the physical hard drive in the data area or data block and can be recovered using retrieving tools. A solution to this problem has been proposed in order to overcome this by overwriting the actual file contents.
