We are using Resilio Sync extensively on Mac, iOS and Synology NAS. We’re at the same time getting rid of “traditional” cloud services. DropBox has gone and Box hangs around only for the odd encrypted payload.
Resilio Sync is fast, easy and extensible. We’d dearly love to be able to store vaults in there, not just on Mac, but for all of our end points.
My simple understanding is it would also get away from using WebDAV which I am growing to hate - particularly with Excel.
