I've seen Arq come highly recommended as an alternative to Duplicati - seems to do mostly the same thing but is commercial ($50) with support. Seems a good bit more user friendly than Duplicati (which can involve a fair bit of computer janitoring).

As far as cloud hosting for backups goes, I found Backblaze B2 to be prohibitively slow from Europe - we're talking uploads at like 150-200 kB/s here IIRC, and I'm on a symmetric gigabit connection. After crunching some numbers I went for Google Cloud Storage instead with the "coldline" storage tier. It's more expensive than Backblaze but uploading at 15 rather than 0.15 MB/s is worth it to me.
