Snapshop: restore from dead?

Hi,

Snapshot looks great, but I failed to find a mention of what would be the most important to me application - restore a WP site from dead.

I can think of too many possible scenarios: the site was hacked (so I need to wipe everything out myself first); a crappy plugin or theme was installed, and it messed up the whole site (so there's no such thing as a WP dashboard anymore); etc.

Will this plugin help me fully recover a WP website in the 2 scenarios above, and how exactly is this done (instructions will be very helpful)?

Thanks in advance!

Yuriu
