Backupscript is a script made by Robin Kelchtermans and Wouter Roozeleer for the course System Engineering 3.
Use the -h or --help flag to get the help function
Make a config file in which you place the directories you want to back up. Once you run the script, it will ask you to show it where your config file is.
Use the -z or --zip flag to get a zipped version of your backup.
Use tar -tvf to see what is in the .tar file, if it's zipped unzip it first.
Use tar -xvf to Extract the .tar file. Again, if it's zipped unzip it first.
This script will make an empty .tar file. You'll have to make a config file in which you'll place the directories you want to backup.
It uses the date command to make sure you'll never overwrite your previous backups and it's easier to sort.
