although many users are still unaware as than Mac or Windowsalso offers an option to be able to restore your system in case any problem occurs. This will allow you to return to a previous state and quickly continue with your work as if nothing happened, even without really knowing what the problem was.
Furthermore, this is an ideal process for all those users who for some reason install many packages and applications to work in the team Either for improve the experience in it or simply by testing programs. So being able to restore the OS will allow you to return to a initial state of your distro and so start from scratch again.
It can also happen that for some reason the computer’s OS has stopped working, forcing users to be able to restore the system and so return to his initial systema procedure widely used by windows users and is now available at Linux. So that you can understand all this a little better, here we are going to show you how restore linux operating system in an easy and fast way, for this follow everything that we will explain below.
When is it necessary to restore the Linux operating system on my computer?
Previously, users thought a lot about it because it did not have a function that would allow restore operating system in case of any error, just as if you could apply on windows. However, currently this process can be carried out in Linux through different ways.
Although it should be mentioned that you will not find any function called “System Restore” in the distribution menus. In this case, it is about finding approaches that adapt to what you need and install the necessary applications for it. Since this will allow you to create snapshots of your system at specific intervals that will allow you to go back to a selected point in time and be able to leave your team as you had it days or hours ago.
Keep in mind that this type of function is recommended to be used when the system has stopped working for some unknown reason, which often happens when any program has been installed or opened. Therefore, if your system does not respond correctly and has stopped working, it is best to restore the linux system and that way you can continue working on it freely.
Is restoring Linux the same as restoring a system backup?
Restore Linux and restore a backup may vary, but the truth of all this is that the backups They are copies of files that are stored in a separate location from the files themselves, this in order to be able to access them again in the event of a system error. Backups rarely include everything on a disk, if they do then they are called disk clones or disk images.
When these copies are made, all both user and operating system data and many more. Thus, disk images can be used to perform a bare metal restore process where the entire contents of a hard drive are backed up to a bare metal computer. While system restores are considered as states that keep a File system created at a specific point in time.
Usually these are stored on the same storage device as the file system. They usually include all the directories and files of a file system or at least all those files that are required by the operating system. Because system restores are stored in the same place on the file system, it is possible to be able to roll back, thus getting a disk space saving.
In this way, it can be said that all this acts as a backup copy where only the changes that have been made since the last snapshot that was run on the system. Which means that each of the snapshots will depend on the previous at the time of full system restore. In the case of full or disk image backups, they are independent of other backups and can perform the restore process on their own.
In the case of system restores, in this case snapshots can be said to be very vulnerable to disk errorswhich means that if the disk is severely damagedyou will most likely lose all the information and unable to restore snapshot. One way to avoid this is by creating a snapshot right after install and configure linux distribution and copy it to a separate storage device.
Learn step by step 10 ways to restore Linux from scratch and without errors
Currently you can find that will allow you keep system snapshots so you can run the linux restore process satisfactorily in case the OS suffers some kind of failure. It is worth mentioning that these applications are suitable for novice users so they do not require advanced knowledge for it.
Therefore, follow each of the ways to restore Linux that we will teach you below and select the one that seems best to you:
cronopete
We start this list with cronopete, it can be said that its use is quite simple so you should not have any problem with it. In this case cronopete offers package for distributions Debian, Fedora and Ubuntu, while the Arch Linux users you can find it in AUR.
It should also be mentioned that cronopete it is characterized by combine backup and snapshot paradigms which requires them to save snapshots to an external storage device. By default, it checks your files for changes or modifications every hour, but this time interval can be changed in the settings box. cronopete.
In the case that the patch is run and the file has not been changed during that time, cronopete it just links to it instead of copying the file, this is done in order to save disk space. According to this, it can be said that cronopete is one of the best options for restoring files, since it allows you to scroll through time, thus visually examining all saved versions of files and folders.
To be able to restore the files, you just have to select them and click on “Restore”, in this way they will be copied to the external drive to your current system. Finally, it should be mentioned that cronopete It is also a fairly practical option for what it is full system restorebut at the same time it is also a very good alternative to keep versions of individual files in the linux operating system.
TimeShift
It is a Graphic interface simple, but which can be used from the terminal easily. TimeShift does not include by default what are lthe personal files of the users, but in these cases you can add custom directories to your snapshotsin the case of Ubuntu distributions and derivatives, you can get Developer PPA TimeShift.
In these cases the following lines can be applied:
- sudo apt-add-repository ppa:teejee2008/ppa
- sudo apt-get update
- sudo apt-get install timeshift
In the case of users who have other Linux distributions, they can download the installation file and run it in the terminal through the following line:
- ./timeshift-latest-amd.64.run
You can also find what version is for BTRFS file system that allows the native BTRFS snapshot function. Therefore, the graphical interface of TimeShift It allows you to take snapshots whenever you want or in such a case it can be configured so that it can create them automatically.
In this case you can schedule snapshots to be taken every hour, once a day, weekly or monthly and you can also configure how often you want TimeShift I can delete them. In this case you can find the option called boot snapshots which allows you to create a new snapshot after each system reboot.
The procedure to accomplish this through TimeShift It is very simple, for this the user must simply select the snapshot and choose the location in which it must be restored. The graphical interface offers options for restore snapshots to external devicesas well as the function of clone which allows you to directly copy the current state of the system to another device. The latter is very useful for migrating your operating system to another new computer.
Finally, it should be mentioned that before carrying out this restoration process through TimeShift You will be asked if you want to keep the application settings and will allow you to choose which ones to keep. In this case TimeShift requires that GRUB 2 boots to a restored snapshot.
Back In Time
This is another one of the applications linux that will allow you restore the systemwith Back In Time This procedure may seem really easy to carry out, so it is recommended to be used by all those users who are taking their first steps in this OS.
In the configuration options of this application you will get detailed control of the entire system. The interface in this case acts as a normal file manager and can reach preview all your snapshots, restore files, select folders and search for specific files.
Back In Time can be easily installed from a PPA if you have the ubuntu distribution.
To do this, follow these lines:
- sudo add-apt-repository ppa:bit-team/stable
- sudo apt-get update
- sudo apt-get install backintime-qt4
Regarding the operation of Back In Time it will allow you to create snapshots that include folders of your choice, but in this case you can only restore those to which you have write access. For one increased security snapshots can be encrypted for storage on an external driveon the local file system or in such a case on a network device.
It should also be mentioned that this application is only responsible for updating those files that have been modified. If you want to disable the snapshot option when no changes are required, then you can do it from the option “Setting” and in the section of “Options”. Snapshots can be programs to run daily, weekly, monthly, as many times a day as you want, or just at Restart the system or in such case you can create them manually.
To be able to eliminate them you can do it from the “Setting” and there in “Delete automatically” this allows you to define when you want Back In Time delete the old snapshots and in turn you can protect some of them in case you do not want them to be deleted for this you must place a…
