Backup to a cloud service

[Me.B]

can sentora be backed up and restored into a completely new vps without much effort as if nothing had changed? if this was required, what would be the directories/components that would require backup?

No currently there is no import/export tools. But you can do that manually.

Mainly you need to backup ALL DB's.
Also you will need all
/etc/sentora
/var/sentora

you will likely need Main apache/bind/postfix/dovecot config too ( unless you rebuild it with a fresh install).
