Because I need to uninstall Clion and I am worried about problems after uninstalling, I consider using dump for backup just in case.
1. Determine whether there is a dump
If there is, it will be as shown in the figure below
if there is not
sudo apt install dump
2. Start backup
问题一:DUMP: You can't update the dumpdates file when dumping a subdirectory
Solution: remove u
dump -0j -f 想要备份到的位置.bz2 想要备份的文件
Question 2: DUMP: Cannot open /dev/nvme0n1p9
Solution: add sudo
sudo dump -0j -f 想要备份到的位置.bz2 想要备份的文件
3. Final effect
