Both the SD cards and SSDs are interpreted as block storage devices by the Linux kernel. You should be able to clone the SD card to a SSD with tools such as dd.

spez_ OP ,

Would you happen to have an example? I’m fairly new to all this. Thanks!

Can I do it from the same machine which is running? I only have two devices - my Raspberry Pi NAS and a phone

Edit, it seems possible: raspberrystreet.com/…/how-to-backup-raspberrypi-s… - they provide a dd example

Why dd over rsync?

dd is transferring in blocks while rsync is transferring in files (or file tree). If you wanna clone a disk, the former is a better option as you want a clone and a block device may contain more than one partition.

CAPSLOCKFTW ,

I would argue that rsync is better suited to clone your file system when using linux. Just prepare the partitions (plus point: you can alter partition sizes and reorganise like having a new partition (or even device) for your /home or whatever) and mount them, then

sudo rsync -ahPHAXx --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found} / /mnt

Then fix your fstab and reinstall your boot loader. Way faster than dd and can be done on a running system.

Your preference may vary but I would not recommend anyone trying to “clone” anything on a running system.

CAPSLOCKFTW ,

Why not? Of course you should not install or uninsta anything while rsync runs…

Use dd on the entire disk?

Raspberry Pi4? Then yes, here’s a guide to update your bootloader:

raspberrystreet.com/…/how-to-boot-raspberrypi-fro…

For older models(Pi<4), no but kinda: Afaik oder models could only boot from SD-cards. But that only means the bootloader has to be on the SD-card. So you can copy everything but the bootpartition and change the entry in the /etc/fstab to the new root on the SSD.

spez_ OP ,

Thanks, this looks like it’ll work. I’ll report back

flint5436 ,

I just did some more research and aparently my intel was a bit outdatet (from arount 2020). The guide should still work, though booting from SSD should be working by default and does not require any eeprom-updates. So you can probably start with step 4.

rambos ,

Listen to this guy, he obviously knows better than I do, I was doing that long time ago and dont even remember completely. Was just trying to help while you wait smart guys to answer 🤣

Maybe clonezilla?
