Hi, I was lucky and got a bunch of very good SSDs (Intel NVME enterprise U.2) for free. I built some of them into my server but still have many left and plan to use them for backups. That means that I’ll only connect them occasionally and store them in a drawer or even off-site. I’m aware that SSDs are not meant for long term “cold” storage as they can lose data when not powered on. However, I still really want to use them. This brings me to my question: What do I need to do to prevent data loss? Is it enough to connect them to power every few months and let the controller do its thing? Do I have to mount them or even read/write to them? Is there anything else I have to consider?

Thank you a lot in advance.

Some years ago, I hosted my own matrix server for a few months. I’m an experienced self-hoster, but I remeber that Matrix was paticularly hard to host, requiring weird proxy rules, DNS adjustments, federation never worked reliably and push notifications never worked at all. I ditched the project soon because I also had no real use for it. However, I recently had some ideas where a Matrix server would be useful again. Has anyone attempted to install it recently and can tell me whether the situation has improved? Also, which server do you recommend? There still is synapse but I found it paticularly complicated to host. Dendrite is now archived and the current fork seems to be tuwunel which doesn’t seem to be under very active development.
