    Others have mentioned power - you may want to do some math on drive cost vs power consumption. There’ll be a drive size point that is worth the cost because you’ll use fewer drives which consume less power than more drives.

    Having built a number of systems, I’m a LOT more conscious of power draw today for things that will run 24/7. Like my ancient NAS draws about 15 watts at idle with 5 drives (It will spin down drives).

    More drives will always mean more power, so maybe fewer but larger drives makes sense. You may pay more up front, but monthly power costs never go away.

    Also, I’ve built a 10 drive n NAS like this (because I had the drives and the case, mono and ram). It can produce a lot if heat while doing anything, and it was a significant power hog - like 200w when running. And it really didn’t idle very well (I’ve run it with UnRaid, TruNAS and Proxmox).


  • And while more drives means more failure opportunity, it also means when a failed drive is replaced, it’s likely of a different manufacture period.

    I have a 5-drive NAS that I’ve been upgrading single drives every 6 months. This has the benefit of slowly increasing capacity while also ensuring drives are of different ages so less likely to fail simultaneously. (Now I’m waiting for prices to come back down, dammit).



  • Yea, that’s a challenging part for sure, one that I still deal with.

    It can be done, but you need to configure the sync jobs “just so”. Send only from the phone, don’t sync deletions, etc.

    In the past I’ve setup a master folder on my phone and used subfolders for “upload only” Syncthing shares. Then wherever I put a file on my phone it gets synced to the appropriate folder on my server.


  • Does it have to be SFTP?

    I use both Syncthing and Resiliosync - both are better on battery than conventional file transfer mechanisms, and they don’t require babysitting. They simply sync files as you define.

    Alternatively if you must have FTP/SFTP, I have used FolderSync (Play store or Apk Mirror) since about 2010 - I’ve even bought it twice because it’s such a great app. Though I haven’t upgraded in a while because I don’t like the new UI.

    The free version does pretty much everything the paid version does, and the devs have always been great.

    But I’d use Syncthing, you can even set it to only sync on your wifi and while charging, though I’ve found even syncing a few gigs doesn’t impact my battery (I probably sync 10GB a day while on battery).





  • Without a secondary internet connection this isn’t possible.

    The router is the connection - its the gateway (a term we don’t hear much these days).

    You could setup an independent connection via a cell modem - becoming a secondary connection. This is common for remote locations or even small businesses that need a failover just for management.

    You could even have it on a single machine and have a vpn there. Then you could RDP/VNC to that one machine and manage things from there. I’ve done the VPN this way with Tailscale. One machine has it (I’ve even done it with a Raspberry Pi), then you can RDP/VNC to other machines from there.

    But there’s not much I could see you doing if the gateway is down anyway.
