I just noticed the link to the Passmark software is incorrect. It won't let me edit to correct it so here is the correct link:
You can backup your USB drive by creating a saved image. You can even take that image and clone multiple USB sticks. This guide shows you how to create an image of your USB drive.

I was supposed to go to a cookout this afternoon but due to the weather not cooperating it was cancelled - what better time to see if I can successfully clone a bootable USB?
For testing I used my trusty multi-boot utility 8 GB USB flash drive with Acronis True Image, Acronis Disk Director, G-Parted, Clonezillla and Hiren's.
The destination drive is an 8 GB FAT32 formatted drive with some movie files I'd already seen.
I tried Macrium Reflect free but it wouldn't let me clone the USB drives - I guess you need the paid version.
Instead, I downloaded the Passmark ImageUSB utility. 2 things I like already - it's small (2.38 MB) and portable (NO INSTALLATION REQUIRED). You unzip the file to a directory and run.
I have both source and destination flash drives plugged in when I run.
When it starts you select the source drive then 'create image from USB drive'. This will copy the USB drive to an image file, boot record and all.
Next you select the location to write the file and give it a name (it is saved with the .BIN extension). I named mine 'utils'.
After you click 'yes' on the confirmation prompt you hit the 'Create' button under Step 4 and it will begin the image creation process.
Image creation time will vary depending on your system and whether you have ticked 'Post Image Verification'.
The resultant image file is the same size as the USB drive, in my case 7.21 GB. Once the image file is created the next step is to write it to another USB drive.
The process is almost identical except you choose the drive you want to write to, select, 'Write image to USB drive', select the drive image you just created in Step 3, then click 'Write' in step 4. (I had unplugged the source drive once the image creation was completed)
Yes my Windows 10 PC is slow - it is an old Dell BIOS machine like the OP's.
When it was done writing to the flash drive I rebooted and select the flash drive from the boot menu. It worked perfectly! I even loaded Acronis, G-Parted and Hiren's.
Always keep your image files in a safe place in case you misplace your USB drive recreating it will be a snap1
In summary if you want to backup your bootable USB media with something that is free and easy to use, no installation required and can be used on any Windows PC Vista and higher Passmark's Image USB is what you are looking for.
Well time to take off my PC Tech hat, put on my Plumber's hat and attend to some work around the house that's been needing my attention.
