In that case, my understanding is that you use the backup feature within hosted-engine,
and if you need to recover use that backup, which is an option during hosted-engine
installation.
I’m all new to this, and I know I haven’t read all the administration documentation
(though what I have read is very good). It might be helpful, if it doesn’t exist, to have
a separate “disaster recovery” practices page to cover all the terrible things that could
happen to a running system. The first part would be activities that administrators should
be doing regularly while the system is healthy, then a section on testing the validity of
those backups. Finally, multiple subsections on “if this happens, then use this, this, and
this that you have for section A to recover your system.”
I’d be willing to help create that, since I need to create the documents for our business
systems.

HA hosted-engine cannot help if VM image are broken. HA runs same image on different
nodes, and if current running VM corrupt FS, for example, it cannot run on other nodes
also.
I wrote about this experience here some time ago.
