How to move local backups to new proxmox server

[rklz]

We are migrating from Vmware to Proxmox and have over 100 remote micro environments. Each site has its own hypervisor but no backup server. We are currently using the local proxmox backups. Our proxmox environments, just like the ESXi environments they are replacing each have a backup drive in the server. The backups go to that drive.

In ESXi, if we had a server failure, it was super simple just to put the new chassis in and move the backup drive to the new chassis and then move the backups back to the primary drive and we were up and going.

In proxmox, this seems to be VERY problematic. Since we are not using backup server, how do we move a backup drive to a new chassis and get the backups running on the new chassis AFTER the original server has already failed since there is no Proxmox to Proxmox migration path nor a backup server. Only a drive that contains backups of the VM's running on that chassis?

This is really easy in proxmox ve.
The thing you are missing is that after you add the backup disk to a new node, you need to import the backup disk. (Via the datacenter tab.) After you import the disk, the node will see it and you can do anything like nothing happend.

Edit:
Asuming you are using a single node.
If you use a cluster do not forget to also select the correct node for the backup disk as it otherwise will show up on all the cluster nodes without having the imported disk present.

esxi only works with move because the virtual machine configuration and virtual disk reside in the same location.

Proxmox cannot be used as is because the virtual disks are stored in the specified disk storage location and the virtual machine configuration is stored in /etc/pve/qemu-server.

If PBS or similar software is not used, at a minimum, the storage configuration and virtual machine configuration should be backed up periodically.

Backing up the following information will make restoration easier.
It takes only about 15 minutes to restore the system.

/etc/kernel/cmdline
/etc/default/grub
/etc/modules
/etc/modprobe.d/*
/etc/pve/storage.cfg
/etc/network/interfaces
/etc/pve/qemu-server/*
/var/lib/vz/snippets/*
