Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

Recently helped someone get set up with backblaze B2 using Kopia, which turned out fairly affordable. It compresses and de-duplicates leading to very little storage use, and it encrypts so that Backblaze can't read the data.
Kopia connects to it directly. To restore, you just install Kopia again and enter the same connection credentials to access the backup repository.
My personal solution is a second NAS off-site, which periodically wakes up and connects to mine via VPN, during that window Kopia is set to update my backups.
Kopia figures out what parts of the filesystem has changed very quickly, and only those changes are transferred over during each update.
The Backblaze option is something I've seriously considered.
Any reason this person didn't go with the $99/year personal backup plan? It says "unlimited" and it is for my household only, but maybe I'm missing something about how difficult it is to setup on Unraid or other NAS software. B2's $6/TB/mo rate would put me at $150/mo which is not great.
You can't use the $99/year plan for that. The authorized client only works as a desktop application on Windows and MacOS.
They only needed about 500GB.
And personal is for desktop systems. You have to use Backblazes macOS/Windows desktop application, and the setup is not zero-knowledge on Backblazes part. They literally advertise being able to ship you your files on a physical device if need be.
Which some people are ok with, but not what most of us would want.
You can ship encrypted files you know…..?
Yes. That's not mutually exclusive with Backblaze having access to your backups.
Them having access to them is irrelevant if they’re encrypted. What’s the issue?
You can do that with B2. Just use an application to upload that encrypts as it uploads.
The only way to achieve the same on the backup plan (because you have to use their desktop app) is to always have your entire system encrypted and never decrypt anything while the desktop app is performing a backup.
Did you not read what I said? You use their app, which copies files from your system as-is. Ensuring it never grabs a cleartext file is not practical.
That doesn’t mean it’s not encrypted on their servers…..
Also doesn't mean it is. Or in a way where only you can decrypt it.
The chain of custody is unclear either way. You're not in control.
