I guess I should try booting live from sdcard1 that is bone stock and dd the mmcblk1 image to sdcard2 on the system. At this point would I need to use etcher to put the img of my setup on sdcard1 since it's already bootable? Or just dd the img to sdcard1?
yes boot from sdcard and make sure there is enough space for a compressed copy.
If you want to do "live" backups you would need to use rsync/rsnapshot to copy newer files rather than disk images.
Would I just dd it to an already bootable sdcard or use etcher?
You can't clone a drive while it's active. rsync/rsnapshot copies files and usually doesn't have files change while they're being backed up.
Sorry maybe I should clear it up. I'm currently booting from sdcard1 (which is bootable). I also have sdcard2 in a USB card reader. I'm now dd'ing the Emmc to sdcard2. The Emmc (mmcblk1) isn't active. After I get the zipped img, can I dd it from sdcard2 to sdcard1 while booted off the emmc or do I use etcher to flash it back to sdcard1?
If emmc is idle, and the 2nd sdcard is as well you can just dd from emmc to sd2 and skip the copy to sd1
