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
