-On a server, I backed up the first partition to the second partition, which is commonly known as "Local backup." The specific backup tools are `tar` , `dd` , `dump` , `cp `, etc. can be achieved. But in fact, it is still "Put the eggs in the same basket." Once the hardware fails and cannot boot and start normally, the data still cannot be retrieved.
