Linux backup and restoration ???

Linux backup and restoration ??? -- Linux general technology-Linux technology and application information. For details, refer to the following section. In Windows, you should know that you can use Ghost for backup and restoration. You can restore a Windows system to the original backup state. In Windows, Ghost is a favorite of many backup and restoration tools!
In Windows, I feel like a train, a locomotive head (drive C is also the system disk), and D, E, F, G ...... Z is like a carriage. As long as the Ghost protects the locomotive, this train will be okay. Other system protection tools will also protect the locomotive!
In Linux, it seems like a "Tree". Everything is under the "root. For Linux backup and restoration, tar is the most widely used tool to package the entire system. It is also convenient. tar is available in every Linux. But at the time of restoration, the state of the original backup is not yet available, and restoration is just a simple replacement of the file. For example, the current file is much more than the original backup package. Now, if you restore the file, you can simply replace it, and the excess parts still exist, it is also a redundant file that is "disconnected" from the system. (Just like this, if there are two files A and B, now I have backed up the two files AB. I used the files (downloaded files and installed files) for A while... ... And so on. Now we have a c file. Now we have three files, A, B, and C, and assume that B is the bridge between file A and file C. However, if the original backup package is used for restoration, the AB file will be replaced with the original backup package, in this way, the information in B that has the contact between A and C is replaced, and C becomes A "disconnected" file, while C is still in the system, if the file is not deleted, it becomes an extra file. I don't know if such a file is a "junk file ).
Ghost restoration can be completely restored, no matter whether the files in your system are more than the original backup, or less than the original backup, in the end, it can be restored to the backup. Even a small setting cannot escape the restoration of the Ghost (the virus cannot escape the restoration of the Ghost ).
If a computer doesn't know how to learn Windows, then he will definitely go to the Ghost backup system. If a computer doesn't know how to learn it, people will learn how to mess up the system ", use Ghost to restore the total proportion of the system. It is easy and quick to install the kernel. Some people are not at ease. They also go back to install programs such as the recovery genie. Now, the process of learning Linux is slow. No matter how good Windows is, you have to come back in Linux. Many concepts are different from those of Windows. What is the difference between this and what I have just said about new computers? Some new users only dare to learn in virtual machines or say "play", but do not dare to install and learn on their favorite computers, for example, a snapshot in a vmvm is also a restoration tool. It manages how much effort you have taken on the VM. In the end, only one snapshot can be restored without affecting the local machine. Some new users are bold enough to install Linux on their favorite computers. They are afraid to use the system accidentally and have to reinstall the system. It takes time and effort.
I searched for a lot of "backup/restore" on the Internet, but all of them were Windows, while Linux's "backup/restore" felt poor, most of the above is about tar's "backup/restore". As I have mentioned earlier, I should know. Using tar for backup and restoration is actually better than Ghost, now there are several Ghost versions that support the ext3 format. On the internet, we also say that we use Ghost to back up/restore the Linux system. For Windows, we only need to back up the "locomotive" (drive C ), everyone knows this. Linux is a "Tree" with many partitions (SWAP partitions, root partitions, and boot references partitions... ... And so on. None of these are available on the Internet. Even if there are some details, I will give you a rough idea. I don't feel it is detailed and there are no detailed operation steps.
I have also found some other Linux backup/restoration tools on the Internet, which use the Partimage, g4l, and Mondo Rescue tools for backup ~~~~~ Poor information, not detailed.
Linux users are not familiar with these three categories. 1. Installation and learning in virtual machines; 2. Installation of dual (multiple) operating systems should have at least one Windows system, 3. Only the Linux operating system is available on the server. In the first two ways, I may think that I accidentally paralyze the system in Linux. At least I can return to a Windows system that I am familiar with right away.
I am also a newbie in Linux. I learned from virtual machines some time ago. Now I have installed dual-OS (Xp + Linux) and went to school on my local computer. But I prefer to install dual-OS (Xp + Linux, in the end, the XP system cannot be started normally, and the reference of mbr seems to be achieved... ... Ah ~~~~~, Now I only use a CD to reference Xp. I have tried it on the Internet to learn about how to repair mbr. It is invalid. You have to reinstall the operating system ~~~~~, If there is something like Ghost in Windows to protect the information about Linux, and it is no worse than Ghost, I will drop Windows. In Linux, Windows is completely poisonous, difficult to prevent.
Ladies and gentlemen, do you all use tar for system backup and Restoration? Or thank you for sharing the information.
