Proxmox backup server

Used https://www.youtube.com/watch?v=KxPl8SHREcE&t=146s to setup the Rock Pi X.

Setup Details

• Hardware: RockPi X (x86 single board computer)
• OS: Debian base installation with Proxmox Backup Server installed on top
• Storage: eMMC (required Debian installation workaround)
• IP Address: 192.168.68.50 (static)
• Backup Schedule: Daily at 9:00 PM
• Backup Storage: 1TB external hard drive

Configuration Notes

Reduce logging and journal writes In /etc/systemd/journald.conf:

Storage=volatile
RuntimeMaxUse=50M

Then:

systemctl restart systemd-journald

This stores logs in RAM instead of the eMMC.
