[SOLVED] proxmox-backup-client failed: Error: Operation not supported (os error 95) (500)

I want to migrate a existing server so I setup a new one and added my existing pbs to it.

I also copied backup.enc from /etc/pve/priv/storage/ and made sure sha1 is the same as on the old server.


While I can list the backup storage, trying to restore or showing the configuration fails with

proxmox-backup-client failed: Error: Operation not supported (os error 95) (500)




This is a general zfs raid1 install using the proxmox iso, tmpfs is mounted on rpool same as on the old server

df -h /tmp/

Filesystem        Size  Used Avail Use% Mounted on
rpool/ROOT/pve-1  900G  2.8G  897G   1% /

cat /etc/pve/storage.cfg

Trying to use pvesm gives

Using encryption key from file descriptor..

Both servers are running latest pve 7.3-4, pbs is running latest 2.3-1
