I don’t think it was me but there are a couple of different solutions I could suggest. One is to use a dedicated cloud storage solution (iCloud, Box, Dropbox etc) which includes a file sync app. Alternatively you could find an app that is essentially a nice wrapper for the unix rsync command. The former gives you cloud backup, the latter will probably be cheaper.
