Any Qnap or Synology NAS will do this sort of backup and cloud sync. The question is about redundancy and possible future use cases.DS120j would be a single bays backup NAS. DS220j would be a dual-drive mirror solution- if one drive fails other has a copy.If you may want to use this NAS for something more then backups then value series such as DS118 or DS218 would also allow you to use it for local multimedia.If you need something that has no limits on apps you can install then DS220+ would be a good option. It also comes with an upgradable RAM slot if you need more speed.I hope this helps.
