Linux Backup Tool

For file backups I find very nice and easy this tool:

Rsnapshot, which you can install using: yum install rsnapshot or apt-get install rsnapshot

To configure it use: sudo nano /etc/rsnapshot.conf. For more information of how to configure it see this: http://www.tecmint.com/rsnapshot-a-file-system-backup-utility-for-linux/

For database backups, I use:

automysqlbackup, which you can install using: yum install automysqlbackup or apt-get install automysqlbackup,  and make configuration on /etc/default/automysqlbackup.conf or /etc/automysqlbackup/automysqlbackup.conf
