  • RAID helps protect you from certain failures, and also allows you to add more storage inexpensively. Typically buying multiple small drives is cheaper than one larger drive, but you do have to buy at least one extra drive for failure.

    You do need to plan for backups. RAID is not a backup, it doesn’t protect you from fires, computer failure, or accidentally deleting things. So a backup is necessary. Look into 3-2-1 backup solutions. At least 3 copies of your data, 2 different hardware types (like SSD and HDD), with at least 1 offsite copy.

    People often keep their NAS at home, with a cloud storage provider as an offsite backup, and an external drive for local backup.

    If you have the money, and a family or friend with space, you can buy multiple complete NAS solutions and back them up to each other.









  • There’s no such thing as too simple to document. If you spent time learning how to install it, you’ll need to relearn it if you want to make any changes in the future. If you don’t leave at least some notes as to why you make some decisions, you’ll have to redo your work.

    It’s also good to make notes on every configuration setting. That forces you to understand why the settings are the way they are. If you have a -f in a docker config and you don’t have any understanding of why that’s there, you might not know if it’s a development flag for getting things set up, or if it’s a critical part of your environment.

    It is especially important if any of those parts are exposed to the public Internet. You might have a config set to allow unauthenticated connections and not know it.







  • I mean… Electronics and the Internet are also following the laws of physics. But I get what you mean, levers should be the only activation, and gravity should be the only requirement.

    That being said, electronics in our devices do tend to reduce the amount of water and power that appliances use. Dumb devices are extremely inefficient, even though there are fewer points of failure.

    It sucks that a 1950’s fridge can still function just fine today, but it also is a bigger strain on the power grid, and a leak in the refrigerant would destroy the ozone.
