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.

Nightly automated runs of the chkbit script is the only thing that alerted me to the fact that either the SSD or storage controller in my Mac Mini had issues and was corrupting data. I was very thankful to have already had the automation in place for that exact scenario.
It theoretically shouldn’t be necessary for filesystems that have built-in checksumming.
Can you post your scripts?
This is what I use, will work with any filesystem (it writes hashes in hidden/dot files) and on any OS as long as Python is available: https://pypi.org/project/chkbit/
It runs ahead of my nightly backup. If it fails, the backup won’t proceed.
Edit: Because the script relies on hashing files, it uses tons of both disk IO and CPU when it runs, but the tradeoff is worthwhile to me.
