How to send backups on multiple location? in c/selfhosted@lemmy.world
[–] czardestructo@lemmy.world 3 points 1 day ago

I went a little crazy and setup my own wireguard VPN network, all the remote hosts connect to the VPN and the primary server connects to each of them and pushes backups. Because I use btrfs and lots of snapshots I use btrbk, annoying to setup but now my hourly snapshots get pushed everywhere, minimal bandwidth and it flawlessly has worked for years.

Incremental backups to optical media: tar, dar, or something else? in c/selfhosted@lemmy.world

I do this except the offline copies are raspberry pis, they grab an update then turn their network card off and go black for about a month. Randomly they turn on the network card, pull a fresh copy and go black again. Safe from randomware and automatic.

I have a trailer (workshop) with solar power, batteries, a raspberry pi controlling everything and a cellular hot spot. It pumps all the solar, battery information and light controls over MQTT and home assistant over cellular. So yes its possible, what do you want to do?

Power is a measurement of the velocity and volume of water flowing through a pipe at a given instant*

I'm so sorry, I am officially 'that guy', taking a simple analogy and making it annoying...

I'm laughing to keep from crying.

My 16 year old Samsung TV would like to argue otherwise! It's a beast and 1080p is plenty good for me! But my Samsung kitchen? Holy crap it's all so terrible...

Raspberry pi 4 inside abandoned scooters (www.tomshardware.com)
 

Title says most of it. Spin electric scooters exited the Seattle market and abandoned their scooters all over the city and apparently they have a pi 4 in them!

Ghost Pi - an unconventional backup solution (lemmy.world)
 

I call this nonsense host ‘Ghost’, for me it’s similar to a tape backup solution. Fairly simple concept, it’s an old Pi1 + external mechanical drive that sits dormant with its ethernet off. Once a month, at a random time and random date it enables the ethernet, spins up the drive and pulls data from the main server to update its drive then goes black until next month. The only way to check or maintain the pi is a push button that toggles the ethernet interface. I slapped it together with some scrap wood, spare hardware and screwed it to a 2x4 in a dark corner of my basement. It’s my 5th string backup, the ultimate insurance policy because I’m mental.
