what is the simplest way to run backups on my laptop,as I haven't been running any?

If you have the Complete version of Webroot, that gives you 25GB of data you can use as a backup:

If you don't, then I'd recommend using an online backup service such as BackBlaze:

The offer unlimited backup for just $5 a month - that's what I use on my computer at home and it has saved me from a hard drive crash that would have lost all my photos and data.

Thank's Nic for the tips.I appreciate you taking the time to answer my question. 

You're very welcome!
