Jumping in from the email side - if your "tiny website" sends mail, test that too after restore. SPF, DKIM, DMARC records often live in DNS not backups, but your sending IP reputation doesn't travel.
Had a client restore to Vultr Toronto from Vultr New Jersey, same domain, same records. Deliverability tanked for a week because the new IP range was on a different reputation profile. Not a backup problem exactly, but a restore-surprise problem.
Keep your DNS TTLs low before planned migrations. Learned that the hard way.
