partclone.vfat -c -s     /dev/sdc1          -o    ~/Pine-mate-sdx1of3.pcl

fsck /dev/sdc2

partclone.ext4 -c -s     /dev/sdc2          -o    ~/Pine-mate-sdx2of3.pcl



and then i put anothe sd card  into USB . Exclamation


2)restore

dd if=/root/Pine-mate-MBR.img of=/dev/sdc bs=512

partclone.vfat -r -s /root/Pine-mate-sdx1of3.pcl -o /dev/sdc1

partclone.ext4 -r -s /root/Pine-mate-sdx2of3.pcl -o /dev/sdc2

mkswap /dev/sdc3

thanks for reply .

about  
dd if=/dev/sdc of=~/Pine-mate-MBR.img bs=512 count=10000

10000 is too big .
i don not know best value  .

and
this line hard copy of MBR(?) and partition structure . Idea
if you want full size of partition 1  , you should use gparted Tongue .

and this method is applicable for btrfs arch linux Heart  (partclone.btrfs)

what do you mean by USB?
what about the FIRST SD card, are there still open files when you remove it?
why do you never use command sync?

arch linux PC:USB port------ Exclamation sd card reader Exclamation ------sd card in which pine64 lives .

no,
cloning to img , and then clone to another sd card .
so mass productin is easy Angel .


in btrfs , rsync is impossible
1)btrfs cloning itself

2)and then gparted

This actually has some cool application:  if we start providing a service ( like noobs on Raspberry PI ) to mail out SD cards for folks that don't want to go to the trouble of making their own.

difinitely worth looking into.

sync, not rsync. And it is probably a good idea to do it before removing the target microSD, just in case you yank it out as it's finishing flushing the buffers to disk... although the flashing light (if there is one) on the microSD card reader is usually a giveaway that it hasn't really finished yet.
