Backing up the backup server question.

[jnewing]

So I have a Proxmox Backup Server running and and love it, we backup all our VMs to this server however I would like to in turn backup all this servers backups it holds to the cloud. So my question is would it be enough for me to backup all the /mnt/datastore using something like rclone?

If I had to rebuild the system from total failure, would me copying back in the /mnt/datastore work?

Thanks.

Yes, works as long as you got your encryption key and datastore folder. But annoying as you need to install and configure your PBS from scratch again. Stuff like changing the owner of each single backup snapshot via the webUi can take an eternity as there is no bulk editing...
Would be way better to rent some server in a datacenter, install PBS there and make use of PBS's sync jobs. In contrast to rsyncing to the cloud this could give you some protection against ransomware and human errors as well as allowing you to directly restore a backup snapshot over the internet/VPN without needing to install a PBS and syncing the whole datastore first, before you could start your first restore.
