pbs replication

[TErxleben]

Hi community,

I want to set up an efficient offsite backup, so I have a PBS (A) on the network that I want to be backed up by the offsite PBS (B).
Unfortunately, the internet connection is rather mediocre (I'm in Germany after all ;-).

Now I thought of the following scenario:
- B is initially plugged into the network to be synchronized and "initialized" with data.
- B is unplugged and plugged into the offline network.
- B pulled A is now acceptable over a slow connection because of efficiently using the "rsync" method.
- Now I actually need this final straw on B and want to restore VMs from B to target network A.
- So B should be plugged into network A, because transporting machine B takes 45 minutes and playing it back via the Internet takes about 2 days.
- I want the whole thing without fiddling with fixed IPs.
- Unplugging, plugging and PBS offsite can be accessed internally in the network.

Maybe someone has already realized this?

it's a regular way.
moving back remote PBS to LAN is always possible.
Not recommended, but
DHCP client is possible and
/etc/hosts must be updated if ip change, like a script https://forum.proxmox.com/threads/set-a-dynamic-address-to-pve.119847/post-673479

Instead of dhcp-hacks: What's about assigning an appropriate second static IP to PBS in LAN-B for destination LAN-A?

try it and report
/etc/hosts doesn't support hostname set to 2 ip, irrc PVE/PBS gui doesn't works if /etc/hosts is wrong.
