Is your website backed up? Outside the server?
It’s good if your host backs up the site on their servers. This way if someone edits your website a little bit too vigorously, you can always revert to a previous, a more suitable version.
There are too many stories of hacked websites, fires in server rooms etc – which is why I heartily recommend downloading regularly a version onto your computer and external drives.
Do make sure if you have to do this manually that you download any relevant databases as well. For instance WordPress websites always use a database and you’ll have to go to MyPHP (for instance) to download it.
