Advice cold storage Solution

[testgcd]

I need to save 20TB in duplicate.

Data will only be accessed like once a month for me to add the new files/changes.

 

I currently just have a few of those passport style Western Digital external drives it gets cumbersome going through all of them every time.

 

Any advice for a better solution? What should I get?

 

I decided against a RAID solution, because although the raid drives have parity, those systems have a 1-point failure regardless of the actual hard drives (in case the motherboard/cpu/software etc bricks the entire Synology etc device), and I don't want to in any way risk a loss of data.

Use two 10tb drives and thats only two drives , should be easy to manage

Cloud storage?

 

Multiple nas boxes that backup to each other. Then you don't have a single point of failure.

 

Tapes and optical drives really don't make sense at this scale.

Just use a linux based software raid, if something dies the array will be easily recoverable, you could even build a "recovery usb stick" that will run on anything capable of hosting the drives. If you do it right and build the OS on raid 1 (drives not used for storage) you should be able to literally pull them with the raid drives, shove them in a new case/machine and just boot it.
