Comment Better sync/backup (Score 4, Interesting) 310
First, syncing to cloud is not backup. Second, being at the mercy of a provider doesn't strike me as a good idea in long-term.
Better invest in a NAS. A 2-bay Synology would suffice. 2 4TB drives in Mirrored Raid work great. WD has the "red" line of drives specifically made and tested for NAS storage. They are not as fast but run cool, silent, no vibrations.
Most NAS units run on linux so you can easily add syncing, versioning, "personal cloud", maybe use to play movies on smart TVs via DLNA and so on.
Finally, from time to time do proper backups. For home use, proper backup means burning data on DVD/BD - on 2 separate discs.
