My sincere advice : use the monthly payment payment plan on a bank standing order (not direct debit). If you decide to cancel your account, download your data - delete your data - cancel the standing order with your bank and, only then, tell DropBox to cancel your account.I used a common paid back-up app that creates an encrypted file container of 3Gb and zips it, ready to put wherever I want. The back-up app would not sync directly with DropBox, the app company's help desk would not even consider it but would oblige with most every other cloud storage provider. Uploading these 3Gb blocks took up to an hour each. The uploads would end with a 'finalising' stage which often stuck and prevented any other uploads waiting in the queue from starting. I couldn't even cancel the stuck task as the button was greyed out. All I could do is logout and log back in again and start over.The 'upload in the background' app that they push is invasive and forces you to have a copy of your pending uploads in a folder on your machine. Whilst it is working in the 'background' it uses 37% of your PC resources and reduces everything to a crawl.Downloading one of these 3Gb files took over a day! The whole website is one pushing pointless features, constant upgrade options and longer payment plans. The latest wants your phone number and suggests using a google account. They probably do not realise that google offer a competitive file storage solution.
