The best way to backup a Pi based system is to set it up so a backup is never needed. You write to the SD card once and save the image file. The never wrote to the card again. You can replace the card from your "standard" image file. These Pis will never have a large hard disk attached to them and the entire card image file is only about 4GB
You can take this one step farther and boot the machines off the your network. Run a TFTP server that serves image files to the active machine controllers and then mount all the user files using NFS. One place I worked at did that with desktop computers. they called it "zero configuration" when a computer broke the IT guy simply opened a box and placed a new computer on the desk and because there was not disk inside the computer there were no files to restore, no config files to edit. The BIOS sees there is not hard drive, there is not CDROM there is not floppy dis and no USB stick so it looks on the network for a TFTP server and pulls an image from it when it needs to boot. This DRAMATICALLY reduces down time after a failure. But it also means that all computers are interchangeable so to work on your data you can use any computer in the building equally well. So when your computer breaks you can use any spare unused computer as they all boot the same image file then at log in go and mount your data and you see the same desktop you used last time. This does require a fast network and RELIABLE storage But again for a R-Pi, you are not going to be storing data on the SD card that changes. Set up an NTP server and an auto mount system. SD cards are not well suited to storing user data.
