Because the backup takes up some system resources, the user will find the system slow response when running the backup. 　 If a Linux computer has only one user, you can back up the entire system once a week or month. If there are critical files, they should be systematically copied to a removable disk. 　 Before backup, make sure that the backup device is correctly set. Most tape backup systems can be correctly installed. After the s

Linux is a stable and reliable environment. However, any computing system has unexpected events, such as hardware faults. Reliable backup of critical configuration information is part of any responsible management plan. In Linux, you can perform backup in various ways. The technology involved ranges from very simple script-driven methods to well-designed commercial software. Backups can be saved to remote network devices, tape drives, and other remova

back up the system. Well, let's get down to the truth. 　　 1. Use tar for simple backup and recovery 1.1 backup The tat command can write archive data to a file, tape, or original tape device. The typical syntax of the tar command is as follows: Code: Tar-[c | x | t] [-pv]-f device path1 path2... 　　 Tar requires a parameter command. Generally, c Indicates creation, x indicates extraction (extract), and t in

Disaster tolerance refers to the guarantee that the information system can provide normal application service after various disaster damage, and can be divided into data disaster tolerance and application disaster tolerance. Data disaster tolerance is the base of disaster tolerant system, and it is also the last means to protect the data when calamity occurs.
