Custom remote backup (lemmy.world)

Hi everyone,

I’m visiting some family in another area of the country soon, and have the opportunity to set up a little remote backup server.

Essentially I would like to set something up that I can ssh into and backup photos/videos/documents from my main server periodically once a month or so. Ideally it would be off until I need to turn it on.

I’m looking for ideas on how to best approach this. What kind of hardware would you use in my shoes? I have a couple of spare raspberry pi’s I was thinking to use with an external drive. I was also considering something like those ugreen nas devices that have been popping up. I would ideally set it up and do a sync before I head there, and then just plug it in. Would wake on lan be advised for this?

raspberry pi + USB raid enclosure in mirror mode with 2x HDD

Do you think a pi 3b would be enough for this?

I have two spare low performance 4TB drives I was thinking to use for this. It’s not quite enough though. Would be ideal to find a way to be able to have someone there easily add a drive when needed 🤔

The 3b just has USB 2, so even with slow spinning rust, that's going to be a bottleneck. But it's probably still plenty fast as a remote storage device for media storage.

Edit: said I didn't know OP's use case but in re-reading they did say. Edited accordingly.

Hmm good point on it being usb2. I would only occasionally power it on to sync, and the sync could be 50Mb or 20Gb, but even then I think that should be ok.
