Put a Fat32 formatted SD card in a USB SD card reader/writer and plug it into your Pi USB port.
Read how to format a SD card with Fat32 Here scroll down to the format section.
To start the process open a Terminal window from Accessories menu.
Terminal window ready to go. |
In the open a Terminal window type: df -h
The out put of the df -h command showing the list of mounted devices |
You will get a list of mounted devices. Check the device name, in my case /dev/sdc1. Ignore the last character that is a number, in my case 1. As can be seen this card has been formatted with a Volume name of SITE.
In the screen capture its listed as /dev/sdc1 120G 128k 120G /media/pi/SITE which makes sense because its a 128Gb SD card and has 128k used, and has 120Gb free.
Open SD Card Copier from Accessories menu.
Selecting the SD Card copy tool from the Accessories menu |
In Copy From Device select the internal SD card /dev/mmcblk0
In Copy To Device select the device that matches the device from the terminal list, in my case /dev/sdc
Do not check New Partition UUIDs or it may not work correctly on your copy.
The /dev/mmcblk0 selected as copy from device and the /dev/sdc selected as copy to device |
If your happy with your choices press the yes button |
Getting the new SD card ready for the copy |
Just about ready to start the copy of data |
Copy under way the first four partitions went by quickly |
Your done |
After waiting 10 to 15 minutes you are done. I shutdown and remove the SD card carrier. Now put the copied SD into a safe place.
If you do not have an USB card reader/writer you can use the same method you would use to write an image to a new card. Here is a link to the Raspberry Pi org site detailing how to use your Windows PC to install operating system images. Here is how to do it using a MAC.
-----------------------------------------------------
If after you are up and running and have made some changes and need to back up your system again you can write over the SD card you have made as a backup (as above). The first step ( df -h command) is the same but the out put on the screen looks different. The steps are the same, you are still copying to the sdc (SD Card). You will still copy to /dev/sdc
The window below is the output of the df -h command, showing the different partitions, of the same sd card (sdc).
