IE8 and below simply don't support background-size so you're either going to have to use the AlphaImageLoader Filter which has been supported since IE5.5:

.arrow-big-right {
    display: block;
    width: 42px;
    height: 48px;
    margin-bottom: 1.8em;
    background-image: url(arrow-big-right.png);
    background-repeat: no-repeat;
    background-size: 42px 48px;
    filter: progid:DXImageTransform.Microsoft.AlphaImageLoader( src='arrow-big-right.png', sizingMethod='scale');
    -ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader( src='arrow-big-right.png', sizingMethod='scale')";
}

Or use some method of targeting IE versions via CSS to apply an alternative to your background for IE8 and below users.

It's also worth noting, as Matt McDonald points out, that you may see two images as a result of using this technique. This is caused by the IE filter adding a background image in addition to, instead of replacing, the standard background image. To resolve this, target IE via css using your preferred method (here's a method, my personal favourite) and remove the standard background-image for IE8 and below.

Using the first technique from Paul Irish's blog post to do this, you could use the following:

.arrow-big-right {
    display: block;
    width: 42px;
    height: 48px;
    margin-bottom: 1.8em;
    background-image: url(arrow-big-right.png);
    background-repeat: no-repeat;
    background-size: 42px 48px;
    filter: progid:DXImageTransform.Microsoft.AlphaImageLoader( src='arrow-big-right.png', sizingMethod='scale');
    -ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader( src='arrow-big-right.png', sizingMethod='scale')";
}

.ie6 .arrow-big-right, 
.ie7 .arrow-big-right, 
.ie8 .arrow-big-right {
    background-image: none;
}

How do I make background-size work in IE8?

This question got answered intensively here:

The most popular fix is this background-size polyfill:

CSS background-size not working in IE7/8

That's because background-size is a CSS3 property which isn't supported before IE9.

However, there is a thread which suggests a possible workaround:
How do I make background-size work in IE?

Background-size 100% not working in IE8 and IE7

since background-size is CSS3 specific which is not supported to IE you have to do something like this for it to work in IE

set your html and body to

html {overflow-y:hidden}
body {overflow-y:auto}

wrap the image you want fullscreened with a div #page-background

#page-background {position:absolute; z-index:-1}

then put this in your html file

<div id="page-background">
  <img src="/path/to/your/image" width="100%" height="100%">
</div>

** you will have to use some sort of reset to remove the margins and paddings, something like this

html, body {height:100%; margin:0; padding:0;}

Background Not Stretching in IE8

Using an img with one of the method detailed here: Perfect Full Page Background Image can be compatible with IE8+ or IE7+.

Otherwise it's not that important if your particular browser doesn't understand this or that (except if it's the most important aspect of your page, but it shouldn't be so for a background image). Progressive enhancement and graceful degradation are cool ;)
