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.

I have an old surplus QNAP. I love it. Very capable, easy to setup, easy to use it and forget about it. Mine is set up for RAID5.
Be certain to get a reliable UPS for it. And have a spare drive on hand.
This. Everyone starts off thinking they'll buy a NAS and it will just exist for years to come. There is some maintenance and monitoring involved, and if you "set it and forget it", you can say goodbye to all that data.
Please consider RAID6 or ensure your data is fully backed up. RAID5 falls flat if a drive fails during resilvering the array.
And, because a resilver involves significant load on the remaining drives, it's more likely than you think. If you have drives from the same batch, they likely have the same MTTF.
@RunningInRVA
Please don't label RAID a backup because it is not. RAID 1, 5 or 6 will give you a robust drive pool that is able to recover from a failed drive.
Backups should be done on a different medium and ideally off-site.
@Xaphanos
Well I wasn’t trying to, exactly. Just trying to convey that RAID5 is not considered reliable and that I was urging the commenter to ensure they have a backup if that’s what they are going to use. Regardless of how you configure your NAS, you can always lose data by mistake.
@RunningInRVA Apologies, I have clearly read your comment wrongly.
It's not an extra life, it's another health point. Red mushroom, not green mushroom.
@captain_aggravated It is a little cryptic.
Mario analogy. In Super Mario games, a green mushroom gives you an extra life, a chance to start over from a point in the past. A red mushroom makes Mario bigger, allowing him to survive some damage that would have killed him. Also in many games it makes him able to do things he can't when small. RAID arrays often run faster than individual disks would.
thanks, I'll look into it
