###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.
