How to perform system backup and recovery on Kirin operating system?

Kirin operating system is an open source operating system independently developed in China and is widely used in various scenarios. System backup and recovery is a very important task when using Kirin operating system. Backup systems can prevent data loss due to malfunctions or misoperations, while system recovery can quickly restore normal functionality in the event of a system crash. This article will introduce in detail how to perform system backup and recovery on Kirin operating system, and attach relevant code examples.

1. Backup system

In order to back up the entire system, we can use the rsync tool. rsync is a powerful file and directory synchronization tool that can efficiently synchronize files and directories between different servers.

First, we need to install the rsync tool:

sudo apt install -y rsync

Next, we can use the following command to perform system backup:

sudo rsync -aAXv /* /path/to/backup/folder --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found}

This command will copy all files in the system and The directory is backed up to the specified backup folder, and system files and directories that do not need to be backed up are excluded.

2. System Recovery

When the system crashes or needs to be restored, we can use the backup folder to restore the system.

First, we need to create a new system partition or format the existing partition:

sudo mkfs.ext4 /dev/sdX

Then, we can use the following command to restore the files and directories in the backup folder to the new In the partition:

sudo mount /dev/sdX /mnt
sudo rsync -aAXv /path/to/backup/folder/* /mnt --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found}

This command will restore all files and directories in the backup folder to the new partition.

Next, we need to reinstall the bootloader to boot the new system partition. First, we need to determine the UUID of the new partition:

sudo blkid /dev/sdX

Then, we need to edit the /boot/grub/grub.cfg file and replace root=UUID=xxx with the new partition UUID:

sudo nano /mnt/boot/grub/grub.cfg

Finally, we need to unmount the new partition and restart the system:

sudo umount /mnt
sudo reboot

Summary:

In the Kirin operating system, system backup and recovery is a very important task. By using rsync tool, we can easily backup the entire system and restore it quickly when needed. When restoring the system, we need to create a new partition and use rsync to restore the files and directories in the backup folder to the new partition. Finally, we also need to reinstall the bootloader to start the new system. I hope this article will be helpful for you to perform system backup and recovery on Kirin operating system.

Code example:

# 安装rsync工具
sudo apt install -y rsync

# 备份系统
sudo rsync -aAXv /* /path/to/backup/folder --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found}

# 创建新的系统分区或格式化已有的分区
sudo mkfs.ext4 /dev/sdX

# 恢复系统
sudo mount /dev/sdX /mnt
sudo rsync -aAXv /path/to/backup/folder/* /mnt --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found}

# 重新安装引导程序以启动新的系统分区
sudo blkid /dev/sdX
sudo nano /mnt/boot/grub/grub.cfg

# 卸载新的分区并重新启动系统
sudo umount /mnt
sudo reboot
