Before my RAID on my Mac died, I would perform a scheduled backup every night to an external USB disk. This was easy to setup using Carbon Copy Cloner. It worked flawlessly for years. Now that I replaced the RAID with a DS920+, I'm not sure how to replicate that functionality. There is Hyper Backup and USB Copy but will either or both do what I want? I basically want a clone of the DS920+ on an external drive in case the DS920+ ever completely craps out. I don't want the backup to be a large single backup file because normally you can't copy individual files or folders from those. I want the backup copy to look exactly like and have the same file structure as the DS920+ and perform the backup every day early in the morning. Maybe I'm thick-headed but I'm having a hard time figuring out how to do this. TIA
