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?
I use Backblaze B2 through my Synology NAS to offsite my important data. Most things though I just backup locally and accept the risk of needing to rebuild certain things (like most of my movie/TV media files since I can just re-rip my physical media, and the storage costs are not worth the couple of days of time in that unlikely case).
I really think this is key when thinking about your backup strategy that is specific to self hosting compared to enterprise operations. The costs come out of our pockets with no revenue to back it up. Managing backups for self hosting IMO is just as much about understanding your risk appetite and then choosing a strategy to match that. For example I keep just single copy in B2, since the failure mode I’m looking to protect against is catastrophic failure of my NAS which holds my main backups and media. I then use Proton Drive and OneDrive to backup secrets for my 2FA setups and encryption for my B2 bucket. This isn’t how I would do it at work (we have a fair more robust, but much more expensive setup). But my costs for B2 are around $15/mo which I am fine with. When I tried keeping multiple copies it had grown to over $50/mo before I cared enough to really rethink things (the cost of the hobby I told myself).
