I’ve used the free version of Updraft Plus on multiple websites and find it easy to use with a good range of options for remote (as well as local) storage. So far it’s been very reliable and I would recommend it. I haven’t used a paid version yet as I haven’t felt the need to (the websites I use it for are quite small and straightforward) but, based on the usefulness of the free version, I would certainly pay for it if/when the need arises.
