How do I create a backup script?
There are several options to backup your data in Linux. You can use some freely available software programs, such as fwbackups and Sbackup. However, there is a simple method to backup a directory without installing any additional software.
We create a shell script using variables, the tar command, and the date command to create a dated backup file of a directory and its subdirectories.
A shell script is essentially a file containing a list of commands that are executed in order. If you have a series of commands that you frequently execute in order, it is useful to create a shell script containing those commands. Then, all you have to do is execute the script file to execute the commands.
