All the cameraclubwebsites.co.uk sites are a small part of our wider business Findlay Design www.findlaydesign.co.uk - we’ve been building and hosting websites professionally since 2004.
So yes, the site is secure. We host them on a managed server from this company: www.clook.net so the measures you describe below are all in place.
Regarding backups in particular:
A full back up of the server is run daily (overnight) and would be used to restore a catastrophic failure of the server itself thus restoring your site to the previous day. We don’t run ‘on-demand’ restorations from backups but we would be able to quote a cost to restore to the previous night’s version should you require this. To date no club has needed to do this.
