Question About Backup Proxmox Backup Server Datastore to S3 Wasabi

[gun.k]

Hello everyone,

I'm setting up an offsite backup for the Proxmox Backup Server (PBS) datastore to S3 Wasabi. My goal is to back up only the essential files required to restore all backups and configurations if the PBS server fails and needs a fresh installation.

Questions:

1. Which paths or directories in PBS should I back up to ensure I can fully restore the datastore and server configurations after reinstalling PBS?
2. How would I restore the data from S3 Wasabi back to a newly installed PBS if it fails? Is there a specific process to ensure the datastore and backup jobs return to their previous state?

Thank you

Essential paths to back up:
Configuration Files:
/etc/proxmox-backup
/etc/proxmox-backup/datastore.cfg (for datastore configurations)
Datastore Data:
/var/proxmox-backup
/var/proxmox-backup/datastore (contains the actual backup files)
If you're using SQLite, ensure to back up:
/var/lib/proxmox-backup/database
