Hello,
I use either DD or Partclone. DD is reliable in recreating the whole image but backing up large eMMCs when 6gb is used is time consuming…
Partclone will back up a partition to a file and backs up only used space. I use sfdisk --dump to keep the partition layout the same.
I usually do something like

sfdisk --dump /dev/mmcblk1 > mmcblk1.sfdisk.dump
partclone.ext4 -s /dev/mmcblk1p1 -o ./pinebookpro-mmcblk1p1.partclone -c -N
partclone.ext4 -s /dev/mmcblk1p2 -o ./pinebookpro-mmcblk1p2.partclone -c -N

You can restore to a larger partition without issue and I think you can restore to a smaller partition if the used space of the back is (obviously), less then the available space. And it works with a wide variety of file system types.

Hi vasudhevan,

I want to see the print of df -h

If you have a mounted external disk, specify the mount point for -e option.

I am fixing it now, please update it in about 30 minutes.

#21

I updated the script, please download it again.

Thank you for helping to find the bug.

This is because -e option was added in the previous version. I provided this parameter when I tested it.

However, if this parameter is not specified when running it, it will add an extra \(backslash) to rsync and cause a bug.

Plug in sd card and restart to verify the backup was successful.
