Someone on Lemmy posted a phrase recently: "If you're not prepared to manage backups then you're not prepared to self host."
This seems like not only sound advice but a crucial attitude. My backup plans have been fairly sporadic as I've been entering into the world of self hosting. I'm now at a point where I have enough useful software and content that losing my hard drive would be a serious bummer. All of my most valuable content is backed up in one way or another, but it's time for me to get serious.
I'm currently running an Ubuntu Server with a number of Docker containers, and lots of audio, video, and documents. I'd like to be able to back up everything to a reliable cloud service. I currently have a subscription to proton drive, which is a nice padding to have, but which I knew from the start would not be really adequate. Especially since there is no native Linux proton drive capability.
I've read good things about iDrive, S3, and Backblaze. Which one do you use? Would you recommend it? What makes your short list? what is the best value?
First copy on offline USB disk on my server itself. Disk is turned on, backup done, disk goes off. Once a day.
Second copy on a USB drive connected to an OpenWRT router of my home, the furthest away from the server (in case of fire, I could be able to grab either of the two).
Third copy offsite on a VPS.
I use restic & backrest with great satisfaction.
