I am attempting to convert from OpenVZ (ploop) to Proxmox LXC

Export:
Code: 
vzctl stop 1145 && vzdump 1145 --bwlimit 9999999999999

Import:
Code: 
pct restore 2136 /var/lib/vz/dump/vzdump-1145.tar

The following errors are shown

it seems the resulting backup is not complete? there is no /bin, /var, /lib (and so on) at all...
 
on which version did you create those backups? note that restoring old vzdump backups created by PVE should work, but if you are running some other openVZ stack that also has vzdump that might not be compatible..

How else could I backup the data than vzdump 1145
 
easiest way is probably to create a tar file of the rootfs (you can do this from within the container) and then use that as container template in PVE (to restore using it as backup, you'd also need to put a compatible config file first in the tar archive).
