It's been more than 30 years, can't say things have truly improved yet.

Sentinel data from Copernicus is free and of better spatial resolution than Landsat.

I'm scared to these 'breaking changes' even though I'm not exactly a self hosting newbie. That's because I don't have a proper 3-2-1 backup and I'm afraid I might lose my photos or settings. I've been exploring of setting up immich through a homeserver management tool like runtipi that allows taking backups separately that can be reverted to, in case something goes wrong. Anyone aware of any negatives about that?

Yes, aka Antipodes map . Very useful in case you are interested in makingEarth Sandwich. A place not very far from me has its antipode on a tiny but touristy island. I'm thinking of contacting the popular hotels on the island to put a flyer in their lobby in case anyone is interested in making the sandwich.

Yes, the other answer also suggests this and I think this will do the trick. Thank you for your response.

Phew! I almost believed I was asking for something beyond the scope of linux-fu. English not being my first language may be part of the reason but still I think I covered everything that was relevant.

Yes, that's exactly what I want and your post has given me the clarity I needed. M.2 wifi slots don't support disks so that option is definitely out. I'm going to boot with the latest Ubuntu live OS on a USB and attempt what you've outlined.

I don't have anything really critical on the zfs that is not backed up separately so I'm definitely going to attempt this and learn in the process.

Thank you for taking the time to respond!

The SSD is 256GB while the two HDDs are 4TB each. What kind of zfs config/array do you suggest I create from them?

I get the part that the cloning software does not care for the underlying OS. My worry is the fact that I'll run the cloning software/command from a live USB which will not be able to detect the zfs mirror on my backup drive on its own and thus break the zfs mirror with bad consequences for the existing data. I could not find any commands to make the live USB OS discover and respect the existing zfs configuration.

I'll definitely take this route if the wifi slot will not support the m.2 drive. Thanks for the suggestion.

Why do I need to add my nvme to the zfs pool? That doesn't really make sense.

If the wifi slot does support m.2 drivers (I was just looking for some confirmation/document), it'll solve my problem. Thanks nonetheless.

I would like to avoid buying additional hardware if possible.
