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?
After some research on here and reddit about 6 months so, I settled on Borgbase and its been pretty good. I also manually save occasionally to proton drive but you're right to give up on that as a solution!
The hardest part was choosing the backup method and properly setting up Borg or restic on my machine properly, especially with docker and databases. I have ended up with adding db backup images to each container with an important db, saving to a specific folder. Then that and all the files are backed up by restic to an attached external drive at well as borgbase. This happens at a specific time in the morning and found a restic action to stop all docker containers first, back them up, then spin them back up. I am find the guides that I used if it's helpful to you.
I also checked my backups a few times and found a few small problems I had to fix. I got the message from order users several times that your backups are useless unless you regularly test them.
