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.

Just started self hosting this instance. Nothing on the docs mentioned anything about storage considerations.

This is lemmy.world after 4 weeks:

58G	pictrs
34G	postgres
[–] i_lost_my_bagel@seriously.iamincredibly.gay 80 points 1 year ago (2 children)

Considering this is going to be around a 5 user instance at most I think I'll be good for awhile. Thanks!

[–] manitcor@lemmy.intai.tech 57 points 1 year ago* (last edited 1 year ago) (1 children)

im running 50 users right now, subbed to A LOT of communities, seeing db growth of about 100mb per day.

[–] Pleonasm@programming.dev 18 points 1 year ago (2 children)

That seems high when you extrapolate that to 10000 users, like a larger instance might have.

[–] terribleplan@lemmy.nrd.li 69 points 1 year ago* (last edited 1 year ago) (4 children)

It's all about how many communities your user(s) subscribe to since your instance basically acts as a mirror for those.

My instance has been running for 23 days, and I am pretty much the only active local user:

7.3G    pictrs
5.3G    postgres

edit: I may have a slight ~~Reddit~~ Lemmy problem

[–] Pleonasm@programming.dev 9 points 1 year ago (1 children)

So if you're the only user (let's assume for ease) then, that represents all the updates (posts, comments, votes) from each community that you are subscribed to?

[–] terribleplan@lemmy.nrd.li 16 points 1 year ago (3 children)

Yeah, and I purposely subscribe to (or sometimes have a dedicated "federation helper bot" account I run subscribe to) most of the most popular communities on the most popular instances so I can get a decent sampling of what's going on in the fediverse on the "All" feed. So I assume my storage usage is maybe a bit higher than what an "average" single-user instance may be...

[–] bdonvr@thelemmy.club 4 points 1 year ago

lmao same here. I have a spare account that I use to sub to everything worth subbing to. I haven't automated it yet though.

It won't scale linearly. A lot of those users will be subscribed to subs the instance is already replicating. It would only be new subs that would add to the growth.

[–] bdonvr@thelemmy.club 4 points 1 year ago

And only active subs. And even then, it's just text and tiny thumbnails.

[–] Dran_Arcana@lemmy.world 16 points 1 year ago (1 children)

Question if you know: does a lemmy instance have to be publically accessable to work? Like, if I make an instance on my homelab can the instance "fetch" content and serve it faster locally? Could I reply to a post and have others see it? Etc

Now I wonder how viable it would be to support video hosting. The answer is almost certainly "God no!"

Honestly, Less than I thought!

[–] mruczek@lemm.ee 13 points 1 year ago (1 children)

Interesting, I thought it would be waaayyy more

[–] BigWigglyStyle@lemmynsfw.com 17 points 1 year ago

At the end of the day the vast majority of what needs to be saved is text. If media content is embedded, the the server just has to save the path to the file not the file itself.

[–] bdonvr@thelemmy.club 11 points 1 year ago* (last edited 1 year ago)

Yeah lemmy seems to use just about nothing for data storage.

[–] myersguy@lemmy.simpl.website 11 points 1 year ago

Wow, that is surprisingly not bad given the size of the instance!

[–] lightrush@lemmy.ca 4 points 1 year ago* (last edited 1 year ago)

Feels like this will benefit from some sort of fuzzy deduplication in the pictrs storage. I bet there are a lot of similar pics in there. E.g. if one pic or a gif is very similar to another, say just different quality or size, or compression, it should keep only one copy. It might already do this for the same files uploaded by different people as those can be compared trivially via hashing, but I doubt it does similarity based deduplication.

This is my small instance with way fewer users than lemmy.world.

11G	pictrs
5.2G	postgres
[–] Molecular0079@lemmy.world 9 points 1 year ago (1 children)

Out of curiosity, how long has your instance been up? Just want to get a sense of how fast storage is increasing for you.

[–] Kushan@lemmy.world 7 points 1 year ago (2 children)

How has your Lemmy experience been on a self hosted instance? I'm currently using lemmy.world and it's very error prone, would self hosting reduce those errors at the expense of anything? Does federation take long or do you find you're getting federated content quickly enough?

[–] NettoHikari@social.fossware.space 13 points 1 year ago (2 children)

The experience has been pretty good, to be honest. No instability, easy updates, etc. I find federated content quite quickly, because I use this script to populate the "All" feed.

[–] Kushan@lemmy.world 5 points 1 year ago (1 children)

I didn't make it! :) I think, @fmstrat@nowsci.com made it.

[–] RedWizard@lemmygrad.ml 4 points 1 year ago

Oh this is very cool

[–] bdonvr@thelemmy.club 7 points 1 year ago

You won't get any old content, so that's a downside. You'll only get content after you start federating. Unless someone votes or comments on old content.

Other than that the only downside is spending time maintaining and updating it.

[–] russjr08@outpost.zeuslink.net 29 points 1 year ago

My instance has 13 users, and has been up for 2 months now:

1.5G    ./pictrs
3.4G    ./postgres
[–] A10@kerala.party 27 points 1 year ago (1 children)

Is there any way to purge old data?

[–] holycrap@lemmy.world 34 points 1 year ago (2 children)

I really hope it doesn't get purged if lemmy is to be a Reddit replacement. A lot of the value Reddit had was obscure knowledge and making google searches actually usable.

[–] Molecular0079@lemmy.world 22 points 1 year ago (1 children)

I think as long as the original community the post is in doesn't purge the data, it's fine for other instances to purge if necessary.

Are you planning on donating to instances that don't purge old data?

[–] useful_idiot@lemmy.eatsleepcode.ca 24 points 1 year ago (1 children)

476M ./postgres 1.1G ./pictrs

After 3 weeks

[–] baduhai@sopuli.xyz 4 points 1 year ago

How many users?

[–] tugg@lemmyverse.org 15 points 1 year ago

Small instance with about 3 users and myself online for about 2 weeks.

pictrs   930M
postgres 1.4G
[–] key@lemmy.keychat.org 14 points 1 year ago* (last edited 1 year ago) (1 children)

Depends. If you have a lot of users posting a lot of pictures and you use pictrs out of the box config, then a lot. If you are just running a few users with finite communities being synced then a lot less. The number is going to vary a lot as lemmy grows and gets older so hard to document realistic expectations. But docker images are probably going to take up more disk space than actual contents unless you get quite big. I just threw my PG volume into a tgz to move servers and it's less than a gig.

[–] bdonvr@thelemmy.club 6 points 1 year ago* (last edited 1 year ago)

The lemmy.world admin said above that their instance currently takes up less than 100GB

[–] holycrap@lemmy.world 11 points 1 year ago

Unless they changed all of the comment and post ids to bigints that'll probably bring the site down before it runs out of storage. In defense of the lemmy developers they have been receptive to feedback, so I don't think it'll take long for that to be fixed if it hasn't already.

[–] i_lost_my_bagel@seriously.iamincredibly.gay 9 points 1 year ago (1 children)

lol lemmy died almost immediately after i posted this time to figure out what the hell caused that

[–] i_lost_my_bagel@seriously.iamincredibly.gay 14 points 1 year ago (1 children)

it was because i set a damn server icon

[–] b3nsn0w@pricefield.org 4 points 1 year ago (1 children)

lmao just how powerful is your server icon?

[–] hitagi@ani.social 9 points 1 year ago

My instance eats up almost 100MB everyday. It mostly depends on what your users subscribe to. It was barely growing on my first few days until I invited a couple of friends over to try it out.

[–] lemmy@endlesstalk.org 7 points 1 year ago

After hosting my own instance with just me for ca. 2 weeks:

1.99Gi pictrs

5.21Gi postgres

[–] HKayn@dormi.zone 7 points 1 year ago* (last edited 1 year ago)

My instance dormi.zone has been running for around 3½ weeks now, has a 3-digit amount of users and hosts a community with little more than 1000 subscribers. Here's how much storage it currently takes up:

  • 6.2 GiB postgres
  • 4.9 GiB pictrs

In the default Ansible configuration, storage will mostly be accumulated by log files that are automatically generated by Docker and deleted whenever you restart the Docker containers.

[–] lightrush@lemmy.ca 5 points 1 year ago (1 children)

How many cans-of-beans.jpg can you store?
