Pipe), data copy tool dd, and data compression (compress ). these technologies are discussed below. · PipelinesIs a pseudo file. it exists in the memory and is used for fast I/O operations. the buffer zone of the MPs queue adopts the first-in-first-out mechanism, that is, the write pipeline process writes the buffer header and the read pipeline process reads the tail of the MPs queue. the pipeline creation command is "mknod filename P ". Dd allows us to copy data from one device to another. ·

Article Title: How to Implement backup in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. A common question for Linux system administrators is: how do I back up my system? For windows systems, it is easy to back up data (you only need to click the mouse in menu mode ).

Purpose This White Paper aims to discuss backup, recovery architecture and solutions, and introduce the features of the Cisco MDS 9000 series multi-layer guide and network switches. Introduction Global Enterprises with key business data on servers require continuous application availability. For a large amount of data generated by applications such as supply chain management SCM, Enterprise Resource Planning ERP, and customer relationship management CRM, enterprises must protect their security a

A common question for Linux system administrators is: how do I back up my system? For windows systems, it is easy to back up data (you only need to click the mouse in menu mode ). Linux backup is much more troublesome. If you are not familiar with Linux system files and devices, the situation will become worse. This article discusses how to protect data and related device information in Linux.1. What is backup??In the simplest way, the process of backing up data is to copy important data to othe

complete database recovery, but the database must run in the recovery mode (the business database runs in the non-recovery mode ), this method requires a large number of external storage devices, such as tape libraries. The second type of backup mode is logical backup, which is used by the business database. This method does not require the database to run in the back-to-back mode, which is not only simple, in addition, external storage devices are n

. Everything, Hope everything is normal, perfect is almost impossible. Backup is a way to protect data investment. If you have multiple copies of data, you are not afraid of any damage (all you need to do is recover lost data from the backup ). Correct backup is important. Just as everything in the physical world is related to others, backups will become invalid sooner or later. Make sure that the backup is valid. You do not want your backup to be invalid.
