rockpi-scripts

These are some of the script that are useful for creating and handling rock pi SD card image

Backup Card

This script backup the SD card into the given Image file. This script is used full to create a backup of the SD card to a small image so that you can store.

Usage:

$ ./backup-card.sh <sdcard device> <image filename>

e.g

$ ./backup-card.sh /dev/sdb small.img

An example usage of the script would be. Suppose you have a SD card of 16 GB but the rootfs is only filled with 5 GB, hence you can accomodate all of it into 8 GB image file. To do this

1. Create a file of 8 GB using following command $ dd if=/dev/zero of=small.img bs=1M count=8192
2. Suppose the SD card is in /dev/sdb. Then to backup into small.img execute following command $ sudo ./backup-card.sh /dev/sdb small.img

NOTE

1. This only works for Rock PI 4B Ubuntu Server, please update the number in script from following command

$ gdisk -l /dev/sdb
