  • I don’t see how you wouldn’t have your email on an email providers servers - that’s how email works. You send an email via a provider, they forward it to the destination address you’ve included with the email.

    That destination address is another email provider’s server, which holds it until the receiver connects and downloads it. Email is a store-and-forward system, designed at a time when users weren’t always connected. It still works this way.

    Email is old, so the fundamental mechanics are pretty simple, and encryption wasn’t an option at the time - so it’s sent in the clear. Otherwise it would require both sender and receiver (either at both ends, or the servers) to agree on an encryption to use.


  • At idle, SSD is usually better (like you said if the SSD has proper power management, and that takes research to know).

    Spinning platters are generally still better for power per gig/terabyte, because write time they consume less power than SSD.

    I dont really look at drive power consumption, because even with ~10 drives running in my environment, a single cpu doing anything moderate blows away their power consumption numbers (I’ve tested, not that it was needed, heat dissipation alone makes it clear).

    I have a ten-year old 5 drive NAS that runs 24/7, and it’s barely above room temp. Average draw is a few watts (the number was so low I put it out of my mind, maybe 5 watts - Raspberry Pi territory).

    My SFF desktop is 12w at idle, with either 2 small SSDs (500GB each) or a single large drive (12TB). So much for SSD having better idle power.




  • Scans for open ports run continuously these days.

    Ten years ago I opened a port for something for a couple days - for months after that I was getting regular scans against that port (and others).

    At one point the scans were so constant it was killing my internet performance (poor little consumer router had no defense capability).

    I don’t think the scans ever fully stopped until I moved. Whoever has that IP now probably gets specifically scanned on occasion.

    And just because you don’t run a business doesn’t mean you have nothing to lose.

    DMZ should be enough… But routers have known flaws, so I’d be sure to verify whatever I’m using.











  • Are you looking for selective sync, and just over the LAN or over the internet too?

    If just LAN, there’s many Windows sync tools for this with varying levels of complexity and capability. Even just a simple batch file with a copy command.

    I’ll often just setup a Robocopy job for something that’s a regular sync.

    If you open files over a network connection, they stay remote and remain remote when you save. Though this isn’t best practice (Windows and apps are known for having hiccups with remotely opened files).

    Two other approaches:

    1. ResilioSync enables selective sync. If you change a file you’ve synchronized locally, the changed file will sync back to the source.

    2. Mesh network such as Wireguard, Tailscale, Hamachi. Each enables you to maintain an encrypted connection between your devices that the system sees as a LAN (with encryption). If you’re only using Windows, I’d recommend starting with Hamachi, it’s easier to get started. If mobile device support is needed, use Wireguard or Tailscale (Tailscale uses Wireguard, but easier to setup).
