Backing Up My NAS - HyperBackup or CloudSync

I’m new the NAS world, just setup the DS923+. I was able to setup Apple TimeMachine on our two Macs to direct it to a shared folder on the NAS. All looks good. I also have BackBlaze backing up our 2 Mac’s. I’ve also moved all our data from DropBox onto the NAS. Now I need to Backup the NAS.

I’m confused about what to use, HyberBackup or Cloud Sync, or is there another solution I should use?
