def check!
  super.check do |d|

    d.local.command(compress(nil, nil).first)
    d.remote.command(decompress(nil).first)
  end
end

#copy_cache ⇒ Object

Returns the location of the local copy cache, if the strategy should use a local cache + copy instead of a new checkout/export every time. Returns nil unless :copy_cache has been set. If :copy_cache is true, a default cache location will be returned.
