Replace /dev/sdX in the command above with the actual device of your card reader. On MAC and Linux, run this command on the console: sudo dd bs=1M if=/dev/sdX of=./backup.img Copy the whole SD card to an image file on your hard drive. On Windows, insert the SD card into your reader and start Win32 Disk Imager. You can skip this step and continue with step 2 if you have nothing configured yet or want to start from scratch again. Step 1: Copy the SD card back to an image fileĪssuming you have already installed and configured everything on your SD card, and you want to move this over to the USB drive now. But it can still be useful having the root partition on a thumb drive and the procedure is identical to HDDs anyway, so they are covered here, too. Thumb drives are not really more reliable than SD cards, there is not much gained using them instead of SD cards reliability wise. The RPi’s USB port is not strong enough to power a hard drive on its own. When using an HDD, it has to have it’s own power supply. The number of writes per sector of an SD card is limited, HDDs instead are much more reliable. HDDs (and also SSDs of course) are much faster than SD cards. It is possible to have the root partition on an external USB drive and run RasPBX from there.
