Site down for many hours

[ido]

If the server is subject of an attack it's the worst possibility.

Lot of todays webhosters for contract has to do periodicaly backup
of the hosted sites and in case a single site is under attack ,the hoster can
even help to ricognise or to map the hacker and to restore the damages.

If you Len ,have an indipendent option of backup your site,so maybe
doing let say ones monthly is wisely spent time.
