  3. Can I create two pve-zsync tasks?

    Hi, As a side note, I is highly recomended if you want to use any kind of backup, that the backup MUST be initiated by the buckup system and NOT by the source(security reson only - think that if your source is hacked, and the intouder can delete ALL your cron tasks, and the remote backups) !!!!!

    Hi, This can also be done also for ProxMox(using hetzner firewall), if this you want. You will need to open your udp/ovpn-port and/or ssh(must to have in my opinion). If your ovpn will die, then you could use ssh! Good luck
