Providers whose services I'm currently using use JetBackup, and allow me to do basically one-click restores to their backups. I test it on a regular basis to confirm it (still) works. Like a charm. MDDhosting (my review link) does it every 4 hours on their Plaid platform.
However, I always make sure to have my own set of backups (which I also test to confirm they are usable) - just in case. Having an (encrypted) copy on one's own computer is always a good idea - I use a Western Digital "My Book" 8TB external drive (Amazon affiliate link) for that.

Unfortunately, Hetzner has made their data centre an easy target for areal strikes (didn't Germans learn anything over the past decades?!):
Ts...ts...ts... disclosing the location and making it impossible to miss... amateurs!
That's why I'll see with @Amadex if I could rent his storage - built as a backup storage should be (undisclosed location somewhere in the Solar system):
