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 (donβt cherry-pick information from the title to fit your agenda).
-
No trolling.

Fuck up #1: no backups
Fuck up #2: using SD cards for data storage. SD cards and USB drives are ephemeral storage devices, not to be relied on. Most of the time they use file systems like FAT32 which are far less safe than NTFS or ext4. Use reliable storage media, like hard drives.
Fuck up #3: no backups.
Would an SSD be any better than a pen drive or should it be stored on spinning rust?
Much better. SSDs and HDDs do monitor the health of the drives (and you can see many parameters through SMART), while pen drives and SD cards don't.
Of course, they have their limits which is why raid exists. File systems like ZFS are built on the premise that drives are unreliable. It's up to you if you want that redundancy. The most important thing to not lose data is to have backups. Ideally at least 3 copies, 1 off site (e.g. on a cloud, or on a disk at some place other than your home).
Though not every fail state is going to show up. If you start seeing weird intermittent behaviour from a drive, for goodness sake find a way to back it up immediately.
My mum's new nuc started having some issues, SMART showed perfect drive health. After trying a few things to diagnose, I rebooted to run memtest and check for bad ram, and that was the last time it ever booted into windows. Controller or something on the nvme ssd died. Far too expensive to try and repair for data recovery. Thankfully had a... Somewhat recent backup. Not as recent as we would have liked.
