Firstly, the restore would need to be to a server that does not have this volume group. I don't think you can clone to the same server because there would be naming conflicts.
The restvg command requires a suitable number of PVs to restore to and these are completely consumed by the process, although that might mean there is free space within the recovered volume group.
To get us to a known point, can you confirm how you saved the volume group (did you exclude any files?) along with any information about the original you have, e.g. number & size of logical volumes and if they are mirrored, PP size,
We would then need to know the target disks and if there are any naming conflicts for the target server. The PV names to restore to can differ from the original. We will need to know quite a lot to work out how to help.
Kind regards,
Robin
