Are you backing up your 6TB NAS RAID to another disk? Some NAS will allow you to do this over USB or the network.
I mention this because the RAID itself is not really a "backup". The disks maybe mirrored or use parity (RAID 5, 6, whatever) so the disks themselves may be protected. However, there are several single points of failure in a consumer RAID. If the power supply goes out, your RAID is down. If the controller goes out, your RAID is down. Etc.
Backing up your NAS to another external disk is a good idea.

You asked Cut-Throat but I'll answer too.
I have a single 6TB WD Red hard drive in my QNAP NAS. I leave a 6 TB WD USB drive connected to the NAS.
Every evening, a scheduled task running robocopy on my NUC does a differential backup to the internal drive on the NAS. An hour later, a similar task does a backup from my wife's NUC to the NAS. A couple of hours later, a scheduled task on the NAS does a backup to the attached USB drive.
Periodically, I swap USB backup drives with a neighbor who keeps an offsite copy for me.
When the internal drive on the NAS gets closer to being full, I'll change the scheduled tasks to do backups from our NUCs directly to the USB drive on the NAS. That will free up some space but won't buy a lot of time.
I have USB thumb drives loaded with recovery images for the NUCs and a laptop. I also have full drive C: image backups for those drives.

Yes, I always backup to an external disk and off site storage as well. I do this weekly however..... Having been in Information Systems since 1972, I learned these lessons over 40 years ago.
I also back up my files with an automatic program in the raid itself. I save 60 copies of my data daily(Excluding Music, Photos). In case I screw something up with my financial files and need to go back a month or so.
However, Whenever I have personally relied and used my Backups over the last 20 years, the raid backup system would have been suitable. The only problem I have had is with a single disk crash when I have needed to recover files. Or once in awhile where I have screwed up a financial File and need to retrieve a previous copy.
