Using "dd" is less than ideal for backups. Meaning if you backup your 64GB eMMC and decide to restore it to a SD card, the card MUST be at least 64GB. And in some cases that I have experienced with SATA DOMs, you may have to go up 1 size. (Imagine trying to restore 64GBs to a 63.999GB SD card that calls it's self 64GB.)
I tend to use more advanced, and flexible methods of backup, (Rsync, EXT4 dump, etc...). But, those tend to be more complex that the simple example of "dd".
On my windows PC's I use a program called Macrium Reflect - it takes shadow copies of a hard drive, only saving "active sectors" and applies some compression before saving to an external hard drive. The file it saves is later accessible for individual file retrieval or can rebuild a complete new drive from the saved image.
Is there anything vaguely like that in "ARM" land?
I have a 128GB eMMC in my Pinebook Pro would that otherwise need a 256GB external device to save it to?
