I’ve been using WebDAV with Box virtually flawlessly since early this year. I’m concerned about this announcement (https://community.box.com/t5/Box-Product-News/Deprecation-WebDAV-Support/ba-p/55684). Back in February I had problems with Duplicati and the native Box storage provider (see The requested folder does not exist with box.com). I have not yet tried any simple backups again with the native provider to see if it now works better (I will soon). I know this is hypothetical but in the case that it does not work, I hope the Duplicati devs will work with me from now until Box WebDAV support goes kaput to get my backups going again. I really like Duplicati and it would be a shame for me not to be able to continue using it with my TBs of data that are backed up.
