October 2, 20241 yr 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.
