Hey, this is really useful.

I wanted to ask a few follow-ups, because the jump from 16 GB to 64 GB sounds pretty dramatic:

• What kind of storage were you using when it was struggling — HDD, SSD, NVMe?
• Did you only increase RAM, or did storage / CPU / other settings change too?
• Roughly what kind of workload was this? Number of users, subscribed communities, amount of federated traffic, image-heavy browsing, etc.
• Do you remember what the actual bottleneck looked like — high RAM use, swap, I/O wait, Postgres getting slow, pictrs, federation queue buildup?
• When you say disabling image proxying helped, how much did it help in practice?
• Was this on a recent Lemmy version, or a while back?

I’m trying to separate “Lemmy really needs big hardware” from “a specific part of the stack was the real problem”.

Sorry if some of these questions are a bit basic or oddly specific — I’m using AI to help gather as much real-world Lemmy hosting experience as possible, and it generated most of these follow-up questions for me.

Hey, thanks for sharing this.

I’m trying to get a clearer picture of what a reliable Lemmy backup/restore setup looks like in practice, especially for self-hosting.

A few things I’d be curious about in your setup:

• Are your Proxmox backups enough on their own, or do you also make separate Postgres dumps?
• Are you backing up the whole container/VM image, or do you also separately keep pictrs data, config files, secrets, reverse proxy config, etc.?
• Have you actually tested a full restore from backup onto another machine? If yes, did it come back cleanly?
• Do you do local-only backups, or also offsite copies?
• When you update Lemmy, do you rely on rollback from snapshots if something breaks, or do you have another recovery path?

Main thing I’m trying to understand is whether Proxmox-only backups are “good enough” operationally, or whether people still end up needing app-level backups too.
