I recently faced a deletion of my calendar and notes data inside a third party application ( Horde ) on my online space.
When I told the web hosting provider they replied that they were doing an upgrade to system software (!!) and that third party client applications are not within their reach or backup policy.
They don't even have a backup of my data.
Is this practice acceptable from a web hosting provider, even for individual clients?
I know that backing up my data is my responsibility but I anticipated that backup copies done by the host would be available when needed.
