When backing up files in Centos7, add the backup date to the backup file

Linux uses files as the basis to manage the devices, interfaces, files, startup and application software in the system. Because in this process, the .conf files, script software, shell, etc. of the application system are required to be backed up before editing. Generally, when I operate important files, I always back them up first, such as:

01. Create a new file

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

02. Spare parts test-copy file

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

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

View the backup results

03. How to add backup time

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

View backup results

At this time, it is displayed where the spare part date is added in the backup file
