###Bash Backup Rotation Script

###Description This script allows you to create a backup rotation for your files and mysql database. The backup target can be local or remote (FTP).

The script has 3 backup types

• Daily backup
• Weekly backup (default : perform every sixth day of the week)
• Monthly backup (default : perform every first day of the month)

This script allows you to customize where to backup each backup type. For example you can choose to do daily and weekly backup on local machine and monthly backup on a FTP server.

Each type of backup will have a backup retention(copy). The default retention for every type of backup can be configured.

The backup retention default day is :

• Daily backup : 5 Day ( 5 daily backups )
• Weekly backup : 14 Day ( ~2 weekly backups )
• Monthly backup : 30 Day ( ~1 Monthly backups )

Please consider your storage size when chosing retention settings.

    TARGET_DIR=/target_directory
    
    # The backup directory , DO NOT END THE DIRECTORY WITH BACKSLASH ! 
    SOURCE_DIR=/your_backup_direcory
    
    # Admin email
    MAIL="your_email@email.com"
    
    # Number of day the daily backup keep
    RETENTION_DAY=5
    
    # Number of day the weekly backup keep
    RETENTION_WEEK=14
    
    # Number of day the monthly backup keep
    RETENTION_MONTH=30

4. Make the script executable

    bash backup_rotation.sh
   

6. If the script runs correctly the file will be available in TARGET_DIR. Try to extract the file and check the contents

    tar -xJfv [filename].tar.xz
   

7. To make the backup run daily, put it in a crontab

    crontab -e
   
    #put this line in crontab
    #This will run it 10 minutes after midnight.
    10 0 * * * [path to your backup_rotation.sh]

##2. Backup Type Configuration

To customize the backup type you must alter the LOCAL_BACKUP_OPTION and FTP_BACKUP_OPTION in the configuration script.

LOCAL_BACKUP_OPTION=1
	
FTP_BACKUP_OPTION=2
