free up disc space on linux server caused by mysql backups

I need someone to help me free up some disk space on my Linux server which should be due to mysql backups or something. Last time when I got a database administrator they restored it to around 20GB but it then after 2 months started to build up again. I currently have offsite backup of entire server to amazon. Key Tasks: 1. Reduce hard disc space 2. Add maintenance plan which based on schedule / cron removes unnecessary backups. Need to use TeamView and I would like you to start on this project today i.e. after being awarded without delay. I am using Percona dropin mysql replacement. Please do not upgrade mysql. Used: 34.81GB Available: 2.57GB Total: 39.37GB
