In a recent interview, an insurance company user pointed out that the backup of a large-capacity file system composed of small files, if the backup speed can reach 80gb/hours, is quite good. To this end, I looked at the data, taking the HP tape library as an example, the maximum can be reached 38tb/hour level. The insurance company is also using LTO3 tape drive Library, why is there such a big gap in the sp

The level of enterprise business redundancy depends on the integrity of the data stored on the server. For companies that provide services to cloud storage customers, business cannot be continued without 99.9999% uptime and absolute assurance of data backup and recovery. Therefore, there are several problems to be solved. First, the enterprise must not only ensure that data is backed up in a precise and secure manner, that each packet and byte is protected, and that the data is "clean" enough t

systems in the industry. "With NFS, ZFS, many storage vendors are having a lot of money, and NFS's ZFS developers are being overlooked." " Sho Shunan very feeling. Oracle's acquisition of Sun, in addition to retaining sun's expertise in the disk array product line, even the non-optimistic library product line (Sun has acquired a professional tape library manufacturer StorageTek) also continued. It can be said that Oracle has completely inherited Sun'

you early in the morning and asked you to complete such a program within three weeks: read characters from the keyboard and output them to the printer. You are a very efficient developer. It takes only two weeks to complete the program (copy V1 ): VoidCopy (){Int C;While (C = rdkbd ())! = EOF)Wrtprt (C );} After you compile the program, install it on the company's 234 workstations. Your program runs well and has no problems in the past three months. So my colleagues praised you and the

organize the scheduling of computer work and the allocation of resources to provide users and other software with convenient interfaces and environments. computer operation system is gradually formed and developed with the development of computer research and application, it is the most basic system software in the computer system.Knowing what the system is for, let's look at the development history of the system.(Evolution of how the operating system works--the fifties or sixties of the 20th c

Http://blog.csdn.net/pongba/article/details/621723 Turing machine is a theoretical device designed by Turing to study computational problems. You only need to think about the concept of a finite state machine, but the memory of the Turing Machine (paper tape) is infinite (that is, it can be any longer, "Infinite" is the ancient saying ). The image defined by the Turing machine is like an old-fashioned electronic transmitter: A Reading and Writing hea

-defined data center (software-defined da Ta center) and IT as a service in the future, this product can meet the demand. Each major enterprise has a trust in Symantec. (from official website)Symantec NetBackup Platform automates the implementation of advanced technologies, standardizing operations on a variety of applications, platforms, and virtual environments to help information enterprises streamline their data protection processes. This means that businesses can achieve full protection, ef

ability to virtualize and share physical hardware means that it is not necessary to have an expensive DLT tape or high capacity Blu-ray (Blu-ray) or Hd-dvd burner attached to each machine.2. Main benefitsStorage consolidation: Consolidate all the storage on the server to increase the "rise time" of the program, and simplify management. The entire storage consortium can be centrally managed to remove the "islands" of the disks that need to be maintain

Back up the server and verify the old saying "Do not put all the eggs in one basket ". The basket here does not refer to the backup media or storage location. I am talking about backing up the function roles assigned to the Windows Server 2003 Server. For example, if a domain controller that stores user data is used as a DHCP server, it is not a good idea to back up only one disk of tape. The more roles a domain controller plays, the greater the risk

The first computer was born in 1946--in the mid 1950s, computer work was still being done by hand. There is no concept of operating system at this time.The programmer will load the perforated paper tape (or card) corresponding to the program and data into the input machine, then start the input machine to enter the program and data into the computer memory, and then start the program through the console switch for the data run, the calculation is fini

selection and removal more convenient when packing. If there is a bad block in the tar file, you cannot access the rest of the file, and with Cpio, only the part of the bad block is inaccessible. It uses the command line to start the program like the Tar tool. Afio is a backup utility based on open source code. It can support a variety of backup hardware, such as tape, floppy, ZIP, hard disk, etc., is a very useful tool. Afio is similar to the TAR c
