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.

If you had to redo your self hosting setup, what would you do differently this time around? (self.selfhosted)

Instead of a 4-bay NAS, I would have gone with a 6-bay.

You only realize just how expensive it is to expand on your space when you have to REPLACE HDDs rather than simply adding more.

Yes, but you'll be wishing you had 8 bays when you fill the 6 :) At some point, you have to replace disks to really increase space, don't make your RAID volumes consist of more disks than you can reasonably afford to replace at one time. Second lesson, if you have spare drive bays, use them as part of your upgrade strategy, not as additional storage. Started this last iteration with 6x3tb drives in a raidz2 vdev, opted to add another 6x3tb vdev instead of biting the bullet and upgrading. To add more storage I need to replace 6 drives. Instead I built a second NAS to backup the primary and am pulling all 12 disks and dropping back to 6. If/when I increase storage, I'll drop 6 new ones in and MOVE the data instead of adding capacity.
