Comment on [Help] Improving HDD storage setup for personal server

ImgurRefugee114@reddthat.com ⁨2⁩ ⁨weeks⁩ ago

Others have answered most questions but I just wanted to point out a few things:

NAS is network attached storage: a separate server which makes ‘shares’/volumes available over the local network. A DAS is ‘direct attached storage’ which plugs directly into a machine. Since you have a server, a NAS is probably the right route. techradar.com/…/das-vs-nas-what-is-the-difference

Good that you mentioned both backups and redundancy as they’re not the same. www.tencentcloud.com/techpedia/108368

Some people want a dedicated machine for being a NAS, while others want to make use of the hardware by making it pull double-duty as a server. I have an old PC I loaded up with drives and installed truenas on: I made zfs pools (opposed to raid) and exposed shares to the network. I can set up virtual machines or use “plugins” / jails for hosting other services like immich etc. E.g. www.truenas.com/docs/solutions/…/nextcloud/

Regarding backup versioning, modern filesystems like zfs and brfs have snapshot features. Regarding “one backup”, it depends how important it is to you. www.backblaze.com/…/the-3-2-1-backup-strategy/

Since you have a server, a NAS is probably the right route.

I don’t understand this. Imo, the previous sentence concludes that I want a DAS, not a NAS because I already have a server.

I’ll look into zfs and btrfs. Somehow this topic is really difficult to grasp

  A DAS is more like an external drive where as a NAS is a service reachable on your LAN. Of course, you could use a NAS and plug it straight into your PC for a more DAC-like experience to keep it off your network… It really depends on what you’re after.
  
  It ultimately breaks down to these choice dimensions, and there’s often overlap which may inform one another (in no particular order):
  
  platform hardware
  
  storage medium(s) (ssd, hdd, layout, caches,…)
  
  filesystem(s)
  
  operating system
  
  shares protocol (Samba, NFS, WebDAV,…)
  
  topology (direct attach or where in your network it’s located, vlans and firewalls etc.)
  
  I interpreted ‘server’ to mean you had platform already which you want to turn into a NAS. If you want storage exclusively for your server, then DAS is fine. If you want to have the storage accessible my multiple devices, then you want a NAS.
  
  It depends on your usecase and what features you’re after.

    Thank you! That sounds great! I already own drives and a machine. I just want to upgrade and make it more secure. I don’t need a NAS then.
