Tutorial: How to Perform Backups and Crontab Scheduling on Linux and Unix

Lab 0x06 - Linux Backups, Cron, and Scripting

Overview
This lab should expose the student to backups using tar and chronological tables using scripts. Additional investigation into tar, network backup transfer, and encryption are encouraged.

Create your first backup script:
date +%Y%m%d.%H%M

#!/bin/bash
# Comment/NAME 20200422.2000hrs
# Backup script

var_date=`date +%Y%m%d.%H%M`

ll backups/
ll

Change the files to their final names:

Change the weekly backup to reflect the proper name:

#!/bin/bash
# Comment/NAME 20200422.2000hrs
# Backup script

var_date=`date +%Y%m%d.%H%M`

Configure the chronological table:
vi /etc/crontab
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user command

Can u run more than 1 backup in the same Cron cmd line thing?
And its 2 parts, a scheduler section and a cmd line that tells what the scheduler to do? How do u export the scheduler?
