backing up flash images

Hello. I have decided to back up the flash images on my gs 648p switch.

I back them up to tftp then try to reboot but i always get a bad image header.

it then goes to boot into the default primary. haveing looked at the image files, they are slightly different sizes to the ones stored on the switch. I have tried 3 differnt tftp servers. I'm wondering if it's treated as a text file rather than binary and adding newlines.

Any thoughts ortftp server software that would do the job properly would be greatly appreciated.

see log below.
