Raspberry pi 4 alternative SD copier option

Hi,
I am running Manjaro OS on RPI4 and I am looking to clone my current SD card for backing up. In official RPI repo, there is SD Copier app. However, I do not see it in Manjaro repo. I’ve tried Clonezilla but it did not seem to work well. What options are there?

Back up the /boot partition

Back up the root partition:

rsync -aWxh --stats / /mnt/clone/

Adjust your PARTUUID’s in the new cmdline.txt and etc/fstab by providing the new ones when restoring.

You also can create and image of the root partition with fsarchiver.

The adjust the PARTUUID again in the same places as mentioned above.
