One of the best ways to create backlinks is probably Article Marketing. Why? Because it creates a traffic stream for you as well (if your article is good enough!)

Write an article, above 250 words, that is optimised for the keyword you're targeting and then submit it to EZA (ezinearticles.com). In your resource box, you can have two links. Have one linking back to your site and the other one perhaps linking back to another page in your site (or a web2.0 property you've created - like a squidoo page). You could of course have only 1 link in the resource box.

You can submit articles to many different article directories like ezinearticles, goarticles, articlebase to name but a few. You can also use them on web2.0 sites like Squidoo, Hubpages and even create a wordpress.com blog and put one on there linking your site back. You can create linkwheels like this.

An example of a linkwheel would be like this. Say you submit 6 articles:

1. EzineArticles
2. GoArticles
3. ArticleBase
4. Squidoo
5. Hubpages
6. Wordpress.com Blog

From here, you create a linking structure that will link both to your page and another part of the wheel. So for example:

1 links to 3 and your website
2 links to 4 and your website
3 links to 5 and your website
4 links to 6 and your website
5 links to 1 and your website
6 links to 2 and your website

This is obviously just a quick example, you can get more elaborate with your link-wheels. It's also recommended that for each article you at least social bookmark them.

A good tool to use for Social Bookmarking is OnlyWire. You can get someone on fiverr.com to create you an account and then you can use it to submit to 42 (I think) social bookmarking websites.

Yep, article marketing is a fundamental you'll definitely want to include in any link building strategy.

You can also take advantage of web 2.0 properties and get backlinks there.

Aside from that, try bookmarking, forum profiles, and blog commenting. Altogether, these are some of what I use on a regular basis and it's enough to get you some really good results if done properly.

Any method may work, what you have to do is to understand what is quality back links..
