###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.
