you can mount a container's volumes to be accessible on the host by
calling "pct mount ID". please be aware that this sets a lock on the
container and needs to be reversed by "pct unmount ID" afterwards.

but I would advise you to use vzdump to backup containers - you get a
(compressed) tar archive, the config is backed up as well and you get
consistency "for free" (or almost free ;)). normally, you want to
restore individual containers anyway.
