In the past few years, people's interest in the data archiving increase. As the company's data Explosion Growth, but also to meet certain regulatory requirements, have a longer data retention; and reduce costs to enable data archiving requirements of more and more people's attention. Now data archiving has evolved into cloud-based archiving Solutions . We all know, about 20-30% of the data network is the archive data, 70-80% of the data is static or non-activity, little change in these static data are rarely accessed. These non-activity data stored in the first layer of storage is very expensive and also very inefficient way. However, usually there is a need or a requirement to keep these non-activity data for future reference or to meet certain regulatory requirements. Then ensure that the data Security , Under the premise of ensuring compliance, they can be stored in inexpensive media is significant. To meet these needs, the usual method is through the archive. Unlike backup archive, it is the non-activity data from primary storage to another easily accessible, more affordable secondary storage layer, and then delete it on the local disk resources. This release can be more expensive primary storage space to reduce costs, reduce the backup window, increase operation efficiency, and long-term reliability of data protection. Of a viable, efficient data archiving should be able to provide: scalability, cost efficiency, availability, data protection, long-term. In this article, we take a closer look at the evolution of data archiving process and the different methods of data archiving, these methods are: 1, the traditional tape archive 2, disk-based data archiving 3, Cloud storage archiving Traditional archive This backup file is the traditional tape-based archiving. Part of the process as a backup, backup software application or system device to write data to tape or tape automated database, the data from the disk to be saved to tape. The tape and the data they contain the normal backup and a long retention period specified by separate, usually from 10 to infinite. When the data backup from the server to remove the disk drive when the tape was sent to off-site archive storage device for permanent storage. Benefit of this approach is that the tape is relatively inexpensive, easy to manage, preserve a long time, and provide a very reliable storage, store large amounts of data very efficiently. In order to increase storage capacity, you only need a simple increase in tape on it. You can also use some type of backup device key data to create data copies or extra tape to provide data redundancy. Adverse tape is you have to wait before you can retrieve data from remote tape back, and then it takes time to scan the tape, find the need to restore the data, re-create the tape to store data. In addition, it limits the explosive data growth caused in the past reduce the backup window, limit the ability to retain, there is no practical means to verify the tape media and data storage life of integrity. Disk-based data archiving The past few years the rapid growth of large amounts of data, in today's business Environment Store and access large amount of archive data, the growing demands. Most of the new regulatory compliance requirements such as SOX, along with globalization and the collapse of the traditional corporate structure, not like before, one or two centralized locations, and now the company has several offices scattered in different regions the need for quick and easy access to large archives, research and other business cooperation, thus was born based on disk-based archiving system. Order to meet these new requirements, such as more efficient access to data, storing large amounts of growth of new data, including Electronic E-mail, database. Company began looking for other stores to meet these needs, effective cost control. Archive evolution and modernization of the first step is disk-based solution deployment. Shelf hardware and use of low-cost SATA drives and low-cost NAS devices. Such companies can keep their data in their easy, quick access to the site. However, these early implementations can not fully meet the unique needs of their filing, such as expansion to accommodate the large amount of data to the Pb growth capacity, and long data retention period beyond the basis of the basic RAID6 provides methods to protect and ensure data integrity so as to reach to meet compliance requirements. They also lack ability to automatically manage the archiving process.
