Backups Blow is a simple perl script for use with cron to automate backing up MYSQL databases and Linux filesystems.
So far it has the following features:

    
MYSQL dump and compression (uses a temporary file)
    
FTP transport (no temporary file) (username/password auth)
    
SSH transport (no temporary file) (key auth only)
    
S3 transport (configurable chunk sizes)
    
Commandline specified configuration file to facilitate multiple different backup jobs
    
Configurable backup paths and tar excludes
    
Weekly full backup and incrementals in between
    
Removal of old backups after each new full backup, with a configurable number of full+incremental sets kept

If you are crazy enough to be interested in adding code, just send a patch, I'll try to have marked what I'm working on in the TODO so that we don't overlap
