A Novel approach for unique Data Backup in Cloud Storage

Today's growth of data in IT environments, the IT managements efforts and investments are getting raises in proportion with Data Center expansion, providing data security, adhering to the compliance policies, cooling expanses and increase in staff to manage Data Center. Deduplication is a data reduction techniques where only unique data will be stored as part of backup .Reduction in the size of the data stored in backup destination will address the problems related to Data Center expansion, data security, excessive power consumption and buying expensive data storage devices like file servers, NAS devices etc. Cloud storage in an online storage service over the network where the data will be stored in the cloud. Cloud storage will help to offload the active data on premise to cloud with pay-per-usage model. It'll address the problem related to Data Center expansion, adhering to compliance policies, cooling expanses and increase in staff to manager Data Center. The aim of this paper is to propose a complete backup solution to address the above problems by integrating " Deduplication " and " Backup to cloud " functionalities in Backup application. 1.INTRODUCTION As the IT management expenses (especially Data center management) are exponentially increasing, now the IT focus is on reducing the data center operating expenses. Also now the IT trend is towards the green computing. Green computing [1] refers to environmentally sustainable IT by implementing energy efficient applications and reducing the power consumption. Utilizing the storage efficiently and effectively with minimal or no impact on the environment and with less IT management expenses should be focus while designing backup application. with the growth of data and its usage, nowadays more data is available online. This increase in online storage has increased power consumption and cooling expenses. Reducing the amount of data stored on storage media, while still the same amount of data is online will help to reduce the power consumption and helps to Green IT. Data centers, which have been criticized for its extraordinary high-energy demand, are a primary focus for proponents of green computing. The federal government has set a minimum 10% reduction target for data center energy usage by 2011[2]. Carefully designing a backup solution with Deduplication and cloud storage tightly integrated will help to reduce the IT expenses and environment impact. 2.RELATED WORK Backup applications are meant for protecting the data by making copies of data in secondary storage devices like hard …
