What actions should be performed to restore a website after a DDoS attack?
My shared hosting provider suffices (at least on contract) daily, weekly, and monthly automatic backups; besides that, I also routinely backup my website's filetree and database not automatically into my PC (clouded), so I am quite covered by means of backups to my website.
I never had a DDoS attack that might crash my website (I would guess, alongside the websites of all other customers which their websites are being hosted on the same shared hosting environment); and I don't really know how, if at all, it could effect the "neighboring" websites and my own website's filetrees and databases.
What actions should be performed to restore a website after a DDoS attack (while hoping the attacker would do it just once, before taking any further actions to also prevent such attacks)?
