dd backup fails with "File too large" error despite ample free space on FAT32 partition

I am attempting to back up a drive, but alas I am met with the following issue:

trisquel@trisquel:~$ sudo dd if=/dev/sda of=/media/trisquel/Backup/ImageBackupOfSeptember202024/full-backup.image status=progress
4261118464 bytes (4.3 GB, 4.0 GiB) copied, 77 s, 55.3 MB/s
dd: writing to '/media/trisquel/Backup/ImageBackupOfSeptember202024/full-backup.image': File too large

trisquel@trisquel:~$ cd /media/trisquel/Backup/ImageBackupOfSeptember202024/
trisquel@trisquel:/media/trisquel/Backup/ImageBackupOfSeptember202024$  df -Ph . | tail -1 | awk '{print $4}'
834G
trisquel@trisquel:/media/trisquel/Backup/ImageBackupOfSeptember202024$

As stated, the drive has 834G of free space (far above the 500 GB maximum of the drive to be backed up), and is formatted as FAT32 Is there anything I can do to help remedy this issue? Thank you so much for any help you can provide. ____ **OS**: Trisquel Live Installation Media (an Ubuntu-based live usb system) **Device**: x230 ThinkPad Figure 1: Screenshot from Gnome Disk Utility
