The difference between hot and cold data backup and data archiving
The earliest data archiving applications originated in the mainframe environment, and the IT applications from the mainframe environment at that time were large and relatively mature. Therefore, the difference between archiving and backup is well understood by domestic larger industries and enterprise users, but for companies with a short history of IT applications, a small scale, and limited data volume, the difference between the two may not be so clear.
Basic storage applications mainly include data backup and data archiving. The purpose of archiving is to realize that historical data and information are systematically, scientifically, and long-term preserved, so as to be used by the company's decision-making management, supervision by superiors or third-party institutions. The opposite is true of backups, whose purpose is the immediate use of data to ensure business continuity, or to restore the business in the shortest time when the business is interrupted.
In recent years, some major corporate fraud cases have occurred in Western countries, which has made the government and the entire society put forward more stringent requirements for the preservation of corporate data, thereby increasing the status of data archiving to be related to the survival of enterprises and social stability the height of. In addition, the early computers mainly processed text data, but now they have to deal with large amounts of multimedia data. The requirements for storage capacity and speed have fundamentally changed. Enterprises have made higher and higher investments in the preservation and utilization of data. Archiving is an important means for enterprises to effectively manage application data and reduce costs.
Therefore, from the perspective of today's data archiving applications, it is mainly to solve the problems of compliance with corporate data storage regulations and effective management of corporate data assets.
Although data archiving and backup are both storage applications, there are significant differences in technical implementation. In the early days of IT applications, disk arrays were not as developed as they are today, and tape libraries were the main backup technology. Nowadays, hard disks are becoming cheaper and cheaper. Not only have tapes been used in backups, but even some people have proposed to use disk arrays for archiving to completely replace tape libraries. However, due to the technical characteristics of the disk array, the data stored in it is in a hot state.
This means that the disk storage system used for data archiving should not be shut down, and the process of re-powering it is also complicated. While advocating "green computing" today, long-term startup is not conducive to reducing energy consumption. Moreover, the frequency of use of data for decades and hundreds of years is not necessarily high, and the cost-effectiveness of disks and tapes is even more disparate. Therefore, for data archiving, the tape library is still the best choice that cannot be replaced.
CD storage is also considered as a means of data archiving, which is characterized by low price, low technical content, and easy distribution on a large scale. However, its capacity cannot be compared with tape and disk, and the applications it can support are also limited, so it is not suitable for enterprise data center-level data archiving applications.
We all see that the concept of applying ILM (InformaTIon Lifecycle Management) in data archiving has been gradually accepted by users, which can not only help companies improve their data asset management as a whole, and achieve it at the lowest cost Effective management and efficient use of large amounts of data. And with the maturity of the application and the actual needs, we found that data encryption, identity authentication, virtualization and other technologies have gradually entered the application of data archiving, and effectively improved the efficiency of data archiving applications and enhanced data security. Greatly reduces the complexity and cost of operation.
The application of ILM allows us to better consider the various aspects of operability, security, cost and production efficiency when considering the needs of existing data applications, and build a data archive protection infrastructure more rationally and systematically.
