Dear Alim!
This is exactly the reason why we try not to deal with boxes and deliberately write "your server - your problems" everywhere.
https://1b.app/ru/prices/#korobochnye-resheniya-on-site-ustanovka-na-svoy-serverThe nuance is that installation on your own servers is always a problem for both parties, responsibility is blurred, and every sneeze and server support costs money.
For example, you need to set up backups. Where to put them? To the same server? If so, then it makes almost no sense.
If to another server (or several) - then you need +1 server in another location (in another data center), it should also be configured and maintained.
PS: move to the cloud - get:
- data center in Germany or Finland
- will work faster
- no need to pay and worry about server support
- automatic backups to three countries
- on the site you can click and download / expand the backup automatically
