Backups on a Budget

Being on a budget and paying $5 a month to perform backups on a $10-a-month VPS seems a bit excessive. This is how you can achieve that goal gratis.
First and foremost, you don't need to backup every single file on your VPS: Identify which ones need to be backed up; keep a list, if you find it helpful. For example, your web root directory and database are good candidates. Install a cron job that will run every night, say at 4, to backup these essential files:

# Website backup
