Date when the backup file is added to the spare part when Centos7 backs up the file

Linux is based on files to manage devices, interfaces, files, startup and application software in the system, because in the current process, the application system .conf files, script software, shell and so on are required to make backup when editing. Generally speaking, when I operate on important files, I have to back up the files first, such as:

01. Create a new file

# echo "test copy.." > / home/hdnnadmin/test-copy

02. Spare test-copy files

# cp / home/hdnnadmin/test-copy / home/hdnnadmin/test-copy-bak

Or # cp / home/hdnnadmin/test-copy {,-bak}

View the results of the backup

03. Method of adding backup time

# cp / home/hdnnadmin/test-copy {, _ back_ `date'+% Y% m% d% H% M``}

View backup results

It now shows where the spare parts date is added in the backup file.
