When you experimenting with Raspberry Pi, you often wish to go back to a “clean” working state, especially after messing around with installations/configurations.
There are different approaches to this such as creating a virtual environment etc, but nothing more robust nor easier than taking a full backup of the SD card.
Backup SD card
There are few options to backup your SD card, I use “Win 32 Disk Imager” to do this.
- Insert SD card to your PC
Warning – cancel when explorer suggest you to format the disk - Download Win 32 Disk Imager https://win32diskimager.download/
- Install and start Win 32 Disk Imager
- Select location and name your backup file
- Click on Read button to start backing up
Restore SD card
The restore can be done using Win 32 Disk Imager as well.
- Insert SD card to your PC
- Select a backup file
- Click on Write button to start restore
Warning – please make sure you are writing to a correct drive
You can also use balenaEtcher (SD flasher) to restore from a backup file.
