Anyway to set up automatic backups?

[AwHereWeGoAgain]

Hey Guys, Im going to start making customization's and modifications to my pinephone to more finely adjust it to my liking.  The thing is, if I do something I don't like or brick the OS having an emergency backup would be pretty sweet.  I know that a lot of people use Timeshift in the desktop community but I would prefer something that actually makes an image of the SD card.  (I can do this on my laptop by yanking the SD card each time I want to make a large change but I was hoping there might be something out there that would let the pinephone do it with the tap of a button.  Basically I would make a special partition on the SD card just to store my backups and make an image of the boot/root/home partitions.  Normally I would just install a sweet of programs to take care of these needs but I have been finding that a lot of the programs im used to are not set up for the ARM cpu architecture which has been slowing me down a bit.  Any options for me or is it better to yank the SD card and use my laptop to make the images?

Thanks
