What is Dropbox?
Dropbox is a file hosting service operated by American company Dropbox, Inc., headquartered in San Francisco, California, that offers cloud storage, file synchronization, personal cloud, and client software.
Dropbox is extremely useful for any WordPress owners to combine it with their backup process. You can store each of your recurrent WordPress files backup and each of WordPress DB backup archive inside your Dropbox account.
Why use Dropbox?
Any personal Dropbox account has 2GB storage space. This cloud storage space should suffice any small to medium sized DB WordPress sites, for their recurrent WordPress DB backup cycles. However, the free tiers small space storage does not a suffice for any WordPress files backup. You would need to have a really small website (like under 100MB per archive files) to set up a safe backup plan on your Dropbox.
PAID Dropbox Business account
For your personal Dropbox account, you can order a paid version of Dropbox. It starts with 2 TB (2048 GB) of storage space with a cost of €12/user/month (or €120/user/year). This cloud storage space should suffice any medium to huge sized WordPress sites, for their recurrent backup cycles.
Need even more space?
The Dropbox Business Advanced account offers by default as much space as needed for €18/user/month (or €150/user/year).
