This article is about what you need to pay attention to when making backups on Linux servers. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

If you make a general backup, which is better on a daily basis (at least for user files that change frequently), you will help reduce file loss and increase the degree of recovery. The safest way to back them up is to record them in different media, such as tapes, extractable hard drives, and writable cd. Wait.

Making general backups should be a top priority for responsible system managers. Although Linux is a highly reliable operating system, system failures can still occur. It may be due to hardware failure, power outage, or other unforeseen problems. The more common problems come from human error, improper changes, and even the deletion of important files. If you are responsible for managing users on the system, you may often be asked to rebuild files that were accidentally deleted.

If you make a general backup, which is better on a daily basis (at least for user files that change frequently), you will help reduce file loss and increase the degree of recovery. The safest way to back them up is to record them in different media, such as tapes, extractable hard drives, and writable cd. Wait. Then store your backup separately from your Linux system. Sometimes this may not be practical-there may be no fire protection room where you can store backup tapes! Or there is no way to access such an external backup system in the first priority location. Even so, backups can still be made, but with some limitations.

Server backup program

There are several different ways to make Linux backups, including command-line tools found in all Linux distributions, such as "dd", "dump", "cpio", and "tar". Other text type tools, such as "Amanda" and "Taper", are designed to add a more friendly user interface to the backup and save back process. Of course, there are graphical interface tools, such as "KDat". Finally, there are commercial backup tools like "BRU" and "PerfectBackup+". Any one of these backup plans is sufficient to protect your valuable data.

Here is a list of where to get tools, which can be found in "LinuxApplicationsandUtilitiesPage". When deciding how to back up, you may want to consider the following factors:

Portability-the portability of backup (that is,. Is it important to you from one Linux distribution or application Unix backup and save back to another; for example, from Solaris to RedHatLinux)? If so, you may want to choose a tool from the command line (i.e.. "dd", "dump", "cpio", or "tar"), because you can be quite sure that the tool can be found on another * nix system.

Unmanned or automatic backup-is the ability to back up automatically on a regular basis without human intervention important to you? If so, you may need tools and backup media that can support the solution.

User-friendly-is a user-friendly interface important to you? If so, you may want to select a text or graphics interface tool. Commercial applications can provide the easiest interface and technical support.

Remote backup-is the ability to back up and save back from a remote machine important to you? If so, you may want to choose a command line or text mode tool instead of a graphical interface (unless you have a fairly fast network connection and the ability to perform remote Xsessions).

Network backup-is it important for you to back up and save back from a network host? If so, you may want to use command-line tools (such as "tar") that support access to backup devices from the network, or specialized tools such as "Amanda" or some commercial tools.

Media type-backups can be stored in many different media, such as tapes, external hard drives, ZIP disks, or read / write CD. Consider price and reliability, storage capacity, and transmission speed.

Warning: when backing up your system, do not include the files in the "/ proc" pseudo-file system! / proc are not real files, but only look like file descriptions and point to links to the core data structure. Backup "/ proc/kcore", which is actually a camouflage file that contains all the data in memory, which will waste a lot of tapes! You may also need to avoid backing up the "/ mnt" file system unless you have a special need to back up files from CD-ROM, floppy drives, network sharing files, or other installation devices.

Obviously, the process of backing up and saving back varies depending on the backup method you choose. However, in this section, I will discuss the backup methods of two of my most commonly used tools: "tar" (whose name comes from "TapeARchiver"), which is a command-serialized tool that is highly portable in * nix systems, and "KDat", a graphical interface tape backup tool from the KDE suite.

Finally, depending on the backup method you choose, even if the tool is not built on the automatic backup schedule, you can still take advantage of the cron feature to do the automatic backup. Refer to the details of using Cron and Crontab files to automate operations and how to create crontab itinerary files.
