HowTo Make & Schedule Daily & Weekly Backup Scripts
General Overview

Weekly Scripts

Overview:

These scripts are essentially the same as the daily scripts.

The Work:

The only changes to the first script is the changing of every occurance of the word daily to weekly.

The second script file like on the daily script file uses exported variables from the first script, the bigest difference here is the inclussion of the second script from the daily backup. Then it includes more files that are not in the daily backups. Now it is not only nessecary to call this script from the first file, but nessecary to call the second script from the daily backup before backing up any of the new weekly files. This is due to the fact that we only want one file, and in order to accomplish that, the daily script first creates the file, and the weekly continues to append the new files to that archive.

# Imported Variables
# CMD is the command to add a new file or group of files to an existing 
#     tar file.
# DIR is the directory where your backup files are being saved.
# TAR is the name of the tar file to create (this file will be removed 
#     after it has been compressed).
# DIR2 is the location of the backup script files.

# Get The Daily Script Backup Files First.
