Well good afternoon.
Do you know how to copy paste all the info from a sd card to another?! I use raspberry pi 4.
thanx in advance.

We need to know which OS you’re using, but if it’s Windows, you can use the above. On Linux it’s a utility called dd. Either way, it’s easy to Google this. The more important question is why: Is your SD corrupt? Then this won’t help you. Tell us your problem.
well I thought to try using home assistant in my pi4. So I didn’t have a sd card and I had put a card 256gb from my GoPro.
So now I liked much that I didn’t expect. I make so many things and I am bored to do it again from the start.
I have macOS.
Use some partition tool like MiniTool Partition Wizzard, Partition Guru, even dd command and clone all raw disk data. There are many more software to do this, by googling the question you will be able to get effective feedback.
I’m assuming you’re planning on using a smaller card. Doing this could be risky for reasons I’m not going to go into here. Just make a backup of your HA config and DB and copy it across to a new location. Not sure what installation method you’ve chosen, but this won’t be hard. No special tools needed.
Also be aware of the pitfalls of using an SD. You’ll be better off attaching an SSD. Just do it now and save yourself the future headaches.
64gb storage I think will be enough. so why would be risky?!
ok I will be attach an ssd no problem for that.
so when you say just copy it to a new location…you mean to choose the options above?! or I miss something?! because you say no special tools needed.
I’m cautioning you to do something you don’t seem to understand, due to the basic nature of your request. My advice is: Either get a second SD and transfer your config or get an SSD and transfer your config. Since you implied that you had an experimental setup, now is a good time to get some basics in order.
The problem is that you don’t know where the data is written on that card. It’s not necessarily in a contiguous block and SD cards to various things to optimise lifetime and improve redundancy and error correction. If you understand the tools you’re using, you can typically create an image of the original, shrink it by removing empty space, and then write it to a new location. You cannot e.g. directly restore a larger image to a smaller location. Then, after restoring, you need to expand the partition again to fill the physical storage unused space to get optimal use. You don’t have to, but it would be a waste otherwise.
The simplest path is to get an identical SD and do a byte for byte copy, but that’s why I asked whether you’re planning on going smaller. Even with a direct copy method like this, two disks can differ by a few bytes and that could technically fail the transfer or cause other issues. Most of the time it won’t, but that’s just luck (or after careful analysis).
