Kosmos has scheduled backups on a secondary hard drive that run daily and we'll retain up to a week and a copy that's up to a month old.
Backups are a complimentary service and are not always 100% reliable. It's in your best interest to also backup your site and keep a copy locally. If you have a large database driven site, or content management system then you should schedule a monthly backup locally and maintained in an off site location. If for some reason our backups are unavailable or if they have failed, we could then restore your backup. Server failures do happen, along with accidents, forces of nature and fires.
YOU CAN NEVER HAVE TOO MANY BACKUPS!
