many users had thought that with the backup archive is complete separation of data protection measures, however, advanced through the program will combine the two, users can greatly enhance the work efficiency of data protection. Companies of all sizes have one thing in common: they create an ever-present moment, a large amount of data, including customer information, product descriptions, as well as accounting documents. In fact, a lot of internal data to double every year. This level of growth accompanied by data from the data protection is to avoid being accidentally deleted and the impact of the disaster, as well as long-term compliance with regulatory requirements to retain data challenges. In the past, data protection and retained by copying the data onto magnetic tape or transferred to achieve. Recently, however, continue to improve disk storage and archiving of financial solutions for users with the emergence of new options. Backup and archiving complement each other filing with the backup system in the enterprise plays a different, complementary features: backup and recovery for high-speed replication, to reduce the failure of staff error or the impact of the disaster; filing technology to effectively manage data To achieve long-term data retention and access and retrieval. These two features together can be applied to optimize the cost of storage infrastructure to improve overall effectiveness. With an effective backup solution for archiving environment has become more efficient, and can use the backup archive infrastructure to meet their data protection needs. Back-up disaster response personnel as a result of user data may be wrong, hardware failure or major natural disasters and losses, technical back-up for a long time to avoid data loss caused by the well-established methods. Backup best suited to the rapid restoration of lost a lot of information in a short time the entire system will be restored to the original running ability. However, back-up storage management has also become a major problem. A large amount of data on infrastructure and the ability to back up the formation of a severe test. According to Gartner, said the data center to back up only an average success rate of 87%. Many data centers will tell you the ability to successfully recover data even lower. Users back up data to the work of the reserved time is reduced, and the rapid resumption of information you need to improve significantly. Through the effective use of the combination of disk and tape back-up, the user can at a reasonable cost disaster recovery infrastructure to increase throughput and reliability. To further strengthen the traditional use of the copy function of the back-up will help customers meet more stringent data protection requirements. However, if the amount of data to back up the growth has not been restricted, these technologies will become an expedient measure. When the user to backup and retention of data protection as the only solution, which will become a real danger, resulting in a very ineffective, inefficient data management. For example, the majority of users every night for incremental backup, full backup every week and will retain the data to back up 3 months to protect against data was accidentally deleted. The second copy of the data can be copied (or through the delivery of the tape) to a remote location to prevent the disaster by the impact. If we consider the backup to retain data for several years to meet the requirements to retain data, users will greatly increase the backup costs. The increase in the cost of data equal to the increase, especially time, money and personnel costs. Assuming the company to ABC, for example. The company in the production of documents kept 10TB server. The company's strategy is a day in the disk storage on incremental backups, in a week on the entire tape backup. According to the tapes of time to classify, preserve and 3 months and then repeat the process. However, the new corporate governance provisions of the laws and regulations in line with the Government, therefore, requires that all new strategy and financial results for the quarter, the data must be retained for 5 years. Since the ABC network, the company did not distinguish between different types of data, data backup and has been retained for 5 years. In the data used in the production capacity of 10TB under the circumstances, ABC's backup data will be 2.5PB, which has not yet considered the increase in the amount of data. The weekly tape to preserve the 5-year, ABC will be more and more time and resources dedicated to data backup. Improve efficiency through the introduction of the archive file archiving technology, companies can improve backup and recovery service levels while reducing the cost of backup. Technical paper also archived data retention laws and regulations to meet the requirements for use of the file system and document metadata, as well as a comprehensive understanding of knowledge of the contents of the paper document management. According to the document filing system, the actual content of the value of the move or copy files. They also based on documents (including any number of parameters, such as author, date or audit and Sarbanes-Oxley Act, and other customized labels) to find and restore the different documents. In order to effectively manage data filing system queries all the files on the network to provide a detailed directory of unstructured data. In the course of inquiry, the collection system file system metadata extraction and content of the document, so as to the classification of data and information management strategy to lay the foundation for the application. Filing system must provide the following functions: with a sense of the content, for example, not only should the index file system meta-data, should also establish the content of the document index; through information extracted from the content, structure customized metadata tags; the use of strategy In the hierarchical storage of information on the level of archive to reduce the amount of storage; selectively archive data subset (filed by the definition of strategy) to meet regulatory compliance requirements and corporate governance information; provide fast access to archived data. And then to ABC for example. ABC aware of the potential data crisis, the deployment of a filing products have been added to the backup. This product data archive search of the entire network, to create metadata for each file summary. Meta-data, including summary of the file system metadata, meta-data files and automatically customize the metadata. It identified 70% of unstructured data is old data (the last 90 days have not visited), 50% of unstructured data and quarterly financial report. Because of its business in accordance with the value of the development strategy of classification, management and the ability to search documents, filing applications can be used for a variety of real environment. In these circumstances, the need to be saved in a different storage platform of information and intelligence are often quick visit. Some of these applications, including regulatory compliance, legal inquiries, corporate governance and tiered storage. would like to see made for
: backup archive is a big different in order to back up data to ensure that safe and carried out by means of a data protection is a process, the most important in the event of a disaster can be restored, so, under normal circumstances, backup and recovery Is closely linked with that of the user if the backup process very smoothly and the key to the success of the restoration can not be at all times, then all the back-up are futile. As the backup to help protect user data when it played a key role in many users it has become almost all memory, all data is not any sort, completely back up. Of course, this method is indeed played a role, but obviously inferior? D? D low utilization rate of resources to restore the old user access to data and documents are not easy. User data, there is a large part of the fixed content, when they have more than a certain period of time when it can be filed, the filing of-the-art programs to enhance the user's existing storage operation efficiency, saving a great deal of the cost of the most important thing is When users need to access those old files can be quickly and easily. At present, e-mail archiving in the field of management has to flex its muscles in managing explosive growth of e-mail, users of the archive for revolutionary change.
