Finally, your questions are answered

All my servers are currently (and always will be) running Linux. My choice is mainly Ubuntu LTS how ever there are 2 Debian VM's running.

I have got my backups of VM's done over XOA which copies the full image of the VM to an external hard drive.

For File based backups, I have got a Min.io instance kindly provided by Compute market (who are not sponsoring me) where all the files for servers are backed up

Server: Dell R710

Use: Hypervisor

OS: XCP-NG (centos basically)

VM's:

1. Firefly-iii
2. Grafana
3. phpipam
4. invoiceninja
5. JellyFin
6. Librenms
7. Nextcloud
8. Database server
9. Unifi
10. Xen Orchestra
11. Zabbix
12. Media wiki
13. postfix and dovecot with dkim
14. Leantime Project managment
15. https://cachethq.io/
16. Bind dns
17. Nginx Reverse proxy
18. Leantime

I have a few sites that are publically accessible:

• Status page
• Bookstack

All the names link to their respective project. They are all FOSS and run natively on linux!
