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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Not exactly self hosting but maintaining/backing it up is hard for me. So many “what if”s are coming to my mind. Like what if DB gets corrupted? What if the device breaks? If on cloud provider, what if they decide to remove the server?

I need a local server and a remote one that are synced to confidentially self-host things and setting this up is a hassle I don’t want to take.

So my question is how safe is your setup? Are you still enthusiastic with it?

My profesional experience is in systems administration, cloud architecture, and automation, with considerations for corporate disaster recovery and regular 3rd party audits.

The short answer to all of your questions boil down to two things;

1: If you're going to maintain a system, write a script to build it, then use the script (I'll expand this below).

2: Expect a catastrophic failure. Total loss, server gone. As such; backup all unique or user-generated data regularly, and practice restoring it.

Okay back to #1; I prefer shell scripts (pick your favorite shell, doesn't matter which), because there are basically zero requirements. Your system will have your preferred shell installed within minutes of existing, there is no possibility that it won't. But why shell? Because then you don't need docker, or python, or a specific version of a specifc module/plugin/library/etc.

So okay, we're gonna write a script. "I should install by hand as I'm taking down notes" right? Hell, "I can write the script as I'm manually installing", "why can't that be my notes?". All totally valid, I do that too. But don't use the manually installed one and call it done. Set the server on fire, make a new one, run the script. If everything works, you didn't forget that "oh right, this thing real quick" requirement. You know your script will bring you from blank OS to working server.

Once you have those, the worst case scenario is "shit, it's gone... build new server, run script, restore backup". The penalty for critical loss of infrastructure is some downtime. If you want to avoid that, see if you can install the app on two servers, the DB on another two (with replication), and set up a cluster. Worst case (say the whole region is deleted) is the same; make new server, run script, restore backups.

If you really want to get into docker or etc after that, there's no blocker. You know how the build the system "bare metal", all that's left is describing it to docker. Or cloudformation, terraform, etc, etc, etc. I highly recommend doing it with shell first, because A: You learn a lot about the system and B: you're ready to troubleshoot it (if you want to figure out why it failed and try to mitigate it before it happens again, rather than just hitting "reset" every time).

I just started my mbin instance a week or two ago. When I did, I wrote a guided install script (it's a long story, but I ended up having to blow away the server like 7 times and re-install).

This might be overkill for your purposes, but it's the kind of thing I have in mind.

Note1: Sorry, it's kinda sloppy. I need to clean it up before I submit a PR to the mbin devs for possible inclusion in their documentation. Note2: It assumes that you're running a single-user instance, and on a single, small server, with no external requirements.
