AOMEI Backupper is an imaging program. Primarily for imaging your partitions. It has more functions than any other free version- e.g. incremental/differential. Overall, it is the best free imaging program around. It doesn't support phone type storage, though they will be adding that soon. It also has file and folder backup. However that is for backup, not the same as syncing.
If you want a sync type program, Karen's Replicator is excellent, and a couple of others have been mentioned.
