I am mostly set on QNAP TS-473, but open to suggestions. I saw your videos that HDD are not portable between different vendors, and have a followup question on setup and recovery.
– I am planning 4 x 10 TB, each as separate mount, without any RAID. Mounts will be /hot1, /hot2, /cold1, /cold2
I will manually or via cron rsync hot1 -> cold1 and hot2 -> cold2, every 3-5 days
This will help in recovery of deleted files and additional backup.
– As above disk are in non raid configuration – can they be moved/ mounted to different system, in case TS-473 host goes bad.
Yes you can create a separate volume for each drive, Than data will be visible on other NAS because it will not be a RAID drive. I would rather suggest having another NAS in remote location automatically synchronized to avoid disaster situation like flood, fire, burglars etc. Also if you would create RAID across all drives, you can connect all drives to the PC and recover data without putting them in the NAS. Also if NAS is was broken you could just put RAID drives in the other unit and Qnap would recognize RAID and let you access data.
