Restoring backups

I am trying to restore a backup of a mikrotik. I FTP the file off the original one and then onto another one. When I click Restore I get and error message. “Couldn’t restore configuration - file too short (6)”

What is this error and How do I get it to work?

Thanks in advance.

I finally got a good backup off the original box and got it installed on the new one.

What was the problem with the original backup file? Corrupt?

I found the problem to be that when I made the backup script we use that I forgot to tell it to use binary mode to transfer the files. This would mess up the size of the file so that when I used FTP to put the file back on the other mikrotik the size of the file wouldn’t match. This caused the error. Once I used Binary mode for both transfers it work without a problem.
