Bug Description

Description: Ubuntu 16.04 LTS
Release: 16.04

lxc:
  Installed: 2.0.1-0ubuntu1~16.04.1
linux-image-virtual:
  Installed: 4.4.0.24.25

Man ref:
http://manpages.ubuntu.com/manpages/xenial/man1/lxc-copy.1.html

Problem:
The man package references '-B' and '--backingstorage' as aliases of one another, but when the following command is executed:

lxc-copy --name=cache --newname container1 --backingstorage=dir
# as a test I also tried
lxc-copy --name=cache --newname container1 --backingstorage dir

The result is:
lxc-copy: unrecognized option '--backingstorage'

Expected result:
'--backingstorage' and '-B' should be aliases and both execute correctly

Existing workaround:
#Use '-B' instead.
lxc-copy --name=cache --newname container1 -B dir

Steps to recreate:
apt-get update && apt-get install -y lxc
lxc-create --name=cache --template=download -- --dist ubuntu --release trusty --arch amd64
lxc-copy --name=cache --newname container1 --backingstorage=dir

This looks like a typo in lxc_copy.c

static const struct option my_longopts[] = {
 { "newname", required_argument, 0, 'N'},
 { "newpath", required_argument, 0, 'p'},
 { "rename", no_argument, 0, 'R'},
 { "snapshot", no_argument, 0, 's'},
 { "foreground", no_argument, 0, 'F'},
 { "daemon", no_argument, 0, 'd'},
 { "ephemeral", no_argument, 0, 'e'},
 { "mount", required_argument, 0, 'm'},
 { "backingstore", required_argument, 0, 'B'},

Should be "backingstorage" here. Which can be verified with --backingstore=dir
