I'm looking for a solution to enable podcasts and files downloaded to pi are sync'd to my phone when I return home and enable my pictures to be backed up to the pi.
1 - upload the files to dropbox, then sync dropbox on phone - look at using rclone http://rclone.org/
2 - run owncloud and save files to local storage, then sync with app
3 - run bittorrent sync and sync with app
4 - some kind of webserver
Anything else obvious i'm missing?
