Data de-duplication technology is often talked about in recent years, storage is a hot topic. As the market promotion, domestic users of the data de-duplication technology acceptance has also been improved rapidly. While pushing in this hot, people have some confusion.
Duplication works for that? Its users have any value? User acceptance do?
Data de-duplication technology is through some kind of algorithm theory, the storage, backup or archiving data in the duplicate data removed, the retention of a single instance of the data unit, to minimize data storage.
From the practical ways, even though today's business information data storage unit cost is lower, but with further development of information society, enterprise information systems and the rapid growth of information and data so that enterprises need to store or backup data volume of information rapidly up, the business of data storage space large investment. The data de-duplication technology to the real message of traditional IT data storage space to 10 or even 20-fold reduction in the enterprise storage capacity, reduce the cost of space.
In recent years, with the major manufacturers of promotion, users of the data de-duplication technology has some understanding, have begun to try to try some of the basic data de-duplication technology solutions. In particular, in consultation with the relevant product FalconStor users, almost all want to know data de-duplication technology and attempt to purchase, the user through a detailed consultation FalconStor's de-duplication rate of nearly 90% after the purchase.
Duplication of different manufacturers have different ratios, then the ratio for which the user is most appropriate?
Duplication ratio has been the most business concerns, different vendors have data de-duplication ratio is different to that directly touches the user's bottom line. Different vendors to claims that the ratio varies from 20:1 to 50:1, even up to 300:1 or 400:1. Because duplication and detailed backup data and backup strategies directly related to the environment from one to another environment resulting duplication ratio will be a great change, even if they are based on the same data de-duplication algorithms . Therefore, the company released data de-duplication ratio can not be the only criterion for choosing this product.
Duplication ratio and fine particles used in treatment correlated with the degree. In theory, the more detailed particle will bring higher data de-duplication ratio. However, a more detailed particle mean a lot of Hash table, would lead to relatively poor data de-duplication performance and higher CPU consumption. Therefore, in general, 10:1 data de-duplication ratio is very realistic starting point of the assessment, sufficient to meet the planning needs of general business applications.
Safety is our concern, data de-duplication of data security issues have any effect?
FalconStor VTL systems and data deduplication technology can know, duplication feature is enabled, does not change the original data security protection or management; while FalconStor VTL system through the built-in data protection features some improved data security protection, recreational flying VTL built-in data encryption, virtual backup devices such as user rights to access, and increase business users take full account of safety concerns.
Duplication application prospects in China?
With the construction of domestic enterprises deepening of information, the information explosion of data growth, and gradually raise the awareness of risk, data de-duplication technology in the information system must become more extensive.. It can not only directly reduce the backup, archive data storage space, but also in the disaster recovery system to reduce network traffic, thereby reducing storage space for equipment, network construction costs. Greater benefit is to reduce the floor space, energy, human resources hidden costs, so true improved return on investment.
Therefore, data deduplication technology in China is very optimistic about the prospects for the occasion. It can really solve the problem of storage, to help businesses save costs and make better long-term storage and data protection program planning. With the green concept of in-depth advocacy, will lead business users make a conscious choice duplication products or solutions, which meet the development trend of China's green.
