Building first NAS brought a few drives recently but unsure of how to make sure it’s upgradable.
Brought 2 x 8 TB Ironpros & 1 x 8 TB One touch for back up with a 1TB Kingston Flash for offsite important files. The idea was to add a TrueNAS VM to my Proxmox. Plan was to use a ZFS mirror on these 2 drives would be enough to have 8TB useable and then just regularly backup weekly with the onetouch (lot cheaper per TB) and I don’t want to keep it running 24/7. I understand this is not exactly 3-2-1.
The questions I have: Do NAS drives need to be on 24/7 to be protected? (Sometimes I turn of my current server for power savings) Also if I want to upgrade and add drives in the future does ZFS mirror allow that? I read that some RAID types do not.
I’m really new to this but eager to learn. So I’m open to any advice or suggestions. Just want to replace my Onedrive, iCloud and Google Cloud Subscriptions with my own services for storage. Across them I only have 1TB so I felt like 8TB was enough plus storage is expensive these days. I do have a separate Media server device with 1TB SSD storage which is growing but not worried about that at the moment.
