Can’t say I’ve used that… Yet. I like nextcloud because besides being compatible with Linux/Windows and having an Android app, it also has a simple web UI to access the files. It’s probably closer to self hosted OneDrive than anything else I can think of. Kinda like the simplicity of pairdrop though.

Hell yeah, it will. I need one of those bad boys.

Hah. I see your looking into ZFS caching. Highly recommend. I’m running Ubuntu 24.04 Root on ZFS RAID10. Twelve each data drives and one nvme cache drive. Gotta say it’s performing exceptionally. ZFS is a bit tricky, it requires an HBA not a RAID card. You may to to flash the raid card to get it working like I did. After that, I have put together a GitHub for the install on ZFS RAID 10, but you should easily be able to change it to RAIDz2. Fair warning, it wipes the drives entirely.

Do you have any hosting in your home lab? Preferably something for running a docker container, but a hypervisor could do the job too.

Nextcloud is an option if you do. Technically speaking you could properly protect it and make it public. You don’t have to do that though. Any file you upload on your computer could be copied to your phone or vice versa. If it’s public, then this could be done from anywhere.
