I recently purcashed this Synology DiskStation DS412+ 4-Bay and stocked it with 12TB (4x3TB) of storage.
Background...I had some serious HD failures in the past with segate and lost a lost of sentimental records. I am a huge advocate for the digital world but quickly learned it has its pitfalls. Since that time I've been researching my options which eventually led me to invest in the Synology system.
My situation... I run a small home business and therefore store a lot of records and data only. I have a LAN running throughout my home where multiple users access movie, music and picture files(currently at about 2TB but always growing).
My intention... Originally I had though to partition the 12 TB I have in the diskstation and have x2 of the HD's backup the files/data on the other two as well as maintaining back-ups of all other computers as required across my network. But soon came to the conclusion that using the 12TB in the disckstation as a central NAS for this would be best as data storage demands grow. So, I am looking at creating initial backups of network computers etc here on the NAS and storing and all shared data here as well. So therefore I will need to back up this NAS itself capturing all critical data across my entire home network.
I remain sceptical of on-line or remotely located storage and at this stage would prefer to simply have this back-up (Series of HD's) locally positioned in another location at home. I anticipate this to be positioned where Fire/moisture/theft risk is reduced but connected via Ethernet to the switch as is with the rest of the home network hardware.
Any suggestions?

RAID1 is "mirroring" of drives - the basic concept is you take two identical drives (i.e. two 3TB WD Red drives), and you make one 3TB volume out of the two drives. When you write to the array, you are physically writing to both drives at one time (this is theory - keeping things simple).

At work, this make sense - when I lose a drive, and the server is down, I can be losing thousands of dollars an hour. At home, I don't get to watch a movie tonight.....LOL. So at work, I use RAID - as the cost to avoid losing drives is "insurance"....at home - I don't pay.

That being said, I keep backup copies of every computer on my network (all 6 of them) on drives in my main rig. So when my wife saves a file on her hard drive, there is a 0-24...
The issue with NAS, often it wants to create a single RAID array from the drives that are in the NAS. RAID will never replace backups! So plan on backing up the data somewhere!!!! To get 12TB of storage, you are using RAID0, which is striping. if any one of the 4 drives fail - you lose everything....so theoretically you have 4X the chance of a failure.

I have a fairly large computer case, and I put drives in that I use as network shares for data (each computer stores most of their data locally). I have backup drives that Syncback Free backs up across the network at night.

BTW - I am a computer geek that builds servers - I use RAID all the time at work (usually RAID5 or RAID10 depending upon the server), and I never use a RAID array as an OS drive (usually a SSD). I only use RAID on the servers to get speed and redundancy for production servers. I use arrays of 10-20 drives to achieve this. I also have expensive RAID controllers to optimize the drives.

At home - I do not use RAID - just SSD or HDD as a single volume in computers....it isn't worth the headaches. At work, I could have 10-50 clients using a server, and speed/reliability is worth the expenditure....at home - usually there are 2-4 users at any given time, and the need for speed isn't there....I configure a home computer with a SSD for OS (120GB) and a 1TB WD Black drive for data. My rig has a WD Green drive for backing up the data (it is only used during the backup process - usually about 10-15 minutes a day - and spins down when not in use). If you want to share a lot of data - consider the 4TB WD Black drives as network shares. If you are running Windows 8.1 or later, you can use Windows Storage Spaces to create even larger volumes.

Sounds like iv'e set myself up for a terminal heart attack x4 ??? And just increased my risk by the same...
So do you know if there is a way to partition the drives in this system? 2x3TB and 2x3TB in a RAID1 mirrored configuration? BTW using 3TB WD Red
Or is my best option to just continue to use the system this way and set-up an old computer with another 12 TB to image back-up this say once or twice a week?
PS - I'm not a geek... and it took me some googeling to translate your response into layman's terms but really appreciate your coming back to me.

Honestly, for any NAS application, I highly recommend a RAID1 or RAID1E configuration. From some cursory googling, it seems like at least RAID1 should be doable on your NAS device.

You wouldn't have the maximum storage potential of a single 12TB volume, but seriously consider whether or not you actually need that right now. Unless you have an INSANE amount of data, having a 6TB volume with single disk redundancy (i.e. one of the drives can fail without any loss of data) is far, far better for peace of mind.

Personally, I use a Drobo B800fs, because it offers a dead simple, no-brainer way of setting up volumes with either single or dual disk redundancy. If you eventually find that you do want to have a full 12TB usable volume with redundancy, it might be something to look at.

That being said, I keep backup copies of every computer on my network (all 6 of them) on drives in my main rig. So when my wife saves a file on her hard drive, there is a 0-24 hour period in which the backup hasn't run yet, that her hard drive could die and I lose that file. When the backup runs, it creates an exact copy of her important files on my machine on a backup drive. If either the backup or the live drive die - I have a copy. Chances of two drives dying at once are very low.

Remember also - RAID is not a substitute for backups - all the RAID arrays at work are backed up daily....
