Current array consists of 3 data drives and 2 parity drives. All 3tb and all bought used with manufacture dates 2014-2016. I keep an additional spare drive in the server to replace a drive failure immediately. Array is currently 44% full. Starting to think about adding more protection without going overboard (have a second unraid license for backup server but then it's parts/space etc.) So what i'm thinking is buy a single 10-12tb disk in it's own pool. Duplicate all data to that drive. That single disk can remain spun up 24/7 and the main array will spin down 99% of the time. Drives would only spin up for periodic backup of the 'main' disk to the server, thinking weekly? Wondering peoples thoughts on this setup and potentially best way of setting it up? Duplicating shares on both drives? Big disk just having single share with folders that mimic the existing shares? Now it may be asked about other protections so I bought a UPS (pure sine not modified) that server is connected to. Initiates safe shutdown. Flood risk very low. Fire risk is average? Thanks.

Appreciate the replies. I should have asked but does it matter if the two versions of unraid are different. The trial was a 6.12 rc but my main unraid server is 6.11.5. Should i reflash the new drive with the same version before copying the config over?

So i setup an unraid server relatively recently and bought a basic license limiting me to 6 drives. I've acquired more drives and so now have a decision to make. The intent is to setup a new license on a different usb that gave me more drives (didn't want to simply upgrade existing license). I'm aware of the process if i want to swap one usb to another and request an updated key, but i essentially want to migrate all my disks to a new license. I have a second usb setup with a trial while i was testing virtulisation so can i just clear that configuration, buy a key, copy contents of existing usb to new usb and then just re-assign disks to the same slots?

So i've just discovered this docker. With latest version installed it wouldn't see my cache drive, would see all other drives in my array though. I forced 2.10 and it recognised and benchmarked my cache drive. The write speeds seem slower than i would expect? Theyre accurate with what i see copying files to the cache drive over a 10gbit lan though
