IT administrators have done a lot of work on data protection, including data backup and management. In order to save money in both human and material resources, they face increasing challenges. This problem arises partly because of the growing number of business data, including database data, e-mail data, file sharing data, and so on. It is also because these data need to be kept for a long time to meet evolving business development needs. To reduce the human and material costs of protecting different kinds of data, many companies adopt a multi-level approach to data storage. At the same time, this tiered storage approach ...

Just a few years ago, duplicate data deletion was a stand-alone feature, and data deduplication offered an alternative to the storage systems in the enterprise backup and archiving department. It also found new uses in cloud gateways to filter out unnecessary chunks of data before entering the array or virtual tape library. Now, it has become a unified computing system of the pre-integrated functionality. Understanding how to use this technology more effectively becomes a requirement.   At the same time IT managers should re-examine storage issues and ask the vendors who provide them with storage. 1. Data de-duplication technology for backup performance ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...
