How to organize an office backup?

Question

Backup

There is an office ~ 10 PCs, all on windows (7-10)
accountants, lawyers, secretaries - office programs (outlook, excel, word, etc.)
We need backups of the system every day / two, in case the hardware is lost so that everything can be restore
What is the best way to organize it?
Backup is needed on a remote server, it is better if it is not very expensive

Answer 1

transfer everyone to the terminal and backup it

Answer 2

Well, if funding is provided (not very expensive, but still), everything is on Windows, and questions of this kind arise :) - then a direct path to commercial backup services (backupblaze, for example). They have a direct application for Windows, which itself does everything.

Answer 3

Bacula/BareOS
