This means, even if you don't use automated backups, and you only made an important backup manually.   Some hosting companies have a policy that automatically deletes any backup it detects, after a short time period (usually no longer than 2 weeks)   In my early years of web design, I personally fell victim to this, and lost everything in one go. The worst part was, I only found this out when my site crashed and I needed to restore...and support politely informed me of their policy!
