How to Backup Raspberry Pi SD Card on Windows

Back up or clone Raspberry Pi SD card means you will create a duplicate copy of the contents stored on the card and use if the original memory card corrupts. Check the steps below to copy the data from one SD card to another with the help of Windows OS.
Step-1: Insert the SD card in your PC. You can use the USB port or a built-in card reader of your system if it is available
Step-2: Download the latest version of software Win32DiskImager from the official resource and install it
Step-3: Open the app when the installation is done
Step-4: At the right corner, you will see an option of choosing the device. Click on it and select the drive in which you inserted the SD card
Step-5: Choose the folder location where you want to save the image file of the data
Step-6: Name the file as per your choice but remember to add the .img extension. For example, raspberry_clone.img
Step-7: Now select ‘Read’ button
Step-8: Wait when the data is being copied to the specified location. Don’t shut down your PC
Step-9: When you get the message of ‘Read Successful,’ attach the card back into your Pi to use it
Step-10: Now, it’s time to insert the SD card into your PC on which you want to make the copy of your original SD memory card
Step-11: Open the Win32DiskImager software and choose the image location that you have made
Step-12: Select the drive of your inserted SD card and choose ‘Write’ button
Step-13: Wait until the process is finished. It can take a while to duplicate the data
Step-14: Remove the memory card and keep it at safe place for future use
How to Clone a Raspberry Pi SD Card on Linux
If you are a fan of Linux and want to clone your Pi SD card using some command lines, then follow the process below:
1) Open the command terminal and enter ‘sudo fdisk –l.’
2) Look for your memory card name indicating with a little less memory space than originally mentioned by the manufacturer (that’s obvious). It may look like /dev/sda followed by the storage size of your SD card
3) Now, enter the command below in the terminal. It will start cloning the data off your memory card to the specified folder name with .img extension
sudo dd if=/dev/sda of=~/raspberry_clone.img
4) You will see a message displayed on the terminal windows with the total records of in/out and the size of data copied in the file
5) Now, remove the original SD card and insert the card on which you want to create the backup. Make sure that the partitions are unmounted on the memory card
6) Enter the command below to write the copied data to the SD card which is to be cloned
sudo dd if=~/raspberry_clone.img of=/dev/sda2
Make sure to follow the right path. Otherwise, you may lose all your content from the system, and the SD may be corrupted. A message will be displayed after the writing process is done.
Clone Raspberry Pi SD Card on Mac OS
At last, I will describe how you can duplicate the content of a Pi SD card on your Mac system. It is the similar process that we have seen for the Linux OS but has some different command names. So, let’s check the methods below:

- Sit back for a while until the process completes. Unmount the memory card after the terminal window displays the message of reading finished
- Unmount the SD card and insert the card which you want to make a clone for your Raspberry Pi data. Again, make sure for the unmount partition on the memory device
- Go to the terminal and write the below command
sudo dd if=~/raspberry_clone.dmg of=/dev/disk

When your SD card is not reading on Mac, you can try to remove the SD card and then switch off the Mac. Leave it for a few minutes, turn it back on, and try again.
Option 3: Check if SD card reader is not working
To access an SD card, you usually need a card reader. When your SD card won't work on Mac, the first thing to check is whether the card reader is working or not. It doesn't matter that you access the SD card by the built-in slot on your Mac or a third-party one. Simply follow these steps to check if the SD card reader is recognized or not.
- 1. Simply click Apple Menu > About This Mac > System Report.
- 2. Find Card Reader under the Hardware list.

Option 4: Check for the connection issue
If the card reader is working fine, then you should check the connections. First of all, make sure you insert your SD card properly. (The metal contacts must face down and point toward your Mac). Secondly, you can test your SD card on a different card reader. If you can access the SD card then, it should be the card reader that has a problem.

Another case for SD card not working on Mac is that the SD card is write protected. When you try to write content to the locked SD card, you cannot modify the files on the locked SD card. To work on the SD card again, you need to safely eject the SD card and adjust the lock slider tab on the card to unlock the card. Then you can access the SD card after you reinsert it to the slot.
Option 6: Insert your SD card in different devices
Another very effective strategy that you can implement is to insert the SD card in different devices, such as phones, digital cameras, or other computers. For instance, you can remove the SD card from your Mac and insert it into your Android phone. If your SD card is still not detected or working on a phone, the card might be damaged or you need to try the following solutions.
