You can add a local path as a storage device. If I recall correctly
though, you add a storage device to the cluster not to the node, so each
node will add that same path a storage device.
So you can't mount a local hard drive and add it as "storage" in a
proxmox cluster, unless that same path exists on all of them.
What I have done at least once is create a samba share on one host, then
mount that share on every host including the local one. You add it to
fstab so it auto mounts at boot.
So if I have host1, host2, and host3 in a Proxmox cluster. I might have
a large disk on host1 at /dev/sdb1 and mounted on /mnt/backups. Then
share it with Samba. Then mount the Samba share as /mnt/proxmoxbackups
on all three nodes. Then add /mnt/proxmoxbackups as a local directory
storage device in the proxmox cluster.
Or....something like that. It was a few years back. Later I just used
a separate server as a network storage device and never looked back.

Yeah, I definitely would store a backup on separate storage, I just
can't seem to find a way to store it locally so that I can then go and
copy it to the separate storage. Ultimately I know I will want to have
storage in place to auto-backup to, I just was hoping for a manual
hold-over in the mean time.

Hi Jason,
You can create a cluster without external storage, but because it is
syncronys replication it will double your write hit. But if you have a
solid network and solid drives you'll barely notice if at all.
For backups I recommend you use separate storage. Otherwise your
risking losing your data if your primary raid array dies.
Thank you,

It isn't obvious to me that there is any way to create or store a
backup without some sort of network storage that is external to the
node(s).
