Site backups are important because problems inevitably appear and you need to be able to take action when disaster strikes.
How often should you back up your WordPress website?
That depends on how often you post new entries and how you would feel if your DB were lost along with all new contents. So it means that you should decide this question by yourself.
I will give you the following backup:
1) Backup of your all WordPress files which includes
- files of WordPress core
- files of WordPress themes
- files of WordPress plugins
- all uploaded images
In short complete manual backup of the WordPress website
2) Backup of your WordPress Database
Your WordPress database contains all posts, comments, categories, tags, taxonomies, custom post fields, options and etc.
If your DB of WP site gets corrupted or erased, you stand to lose everything you have published.
Finally: I can upload backup files on your host or Dropbox.
