  It is highly unlikely that the Dynamic IP had anything to do with this.

  It sounds like the backup software you used overwrote the file, I would
recommend checking the timestamp on the tiny file to see when it happened.
(after the first restore, or during the second backup, etc).

  It is too late, but unmounting the partition as soon as you realize
something is wrong decreases the chance of future file system activity 
damaging your file data, wherever it is on the filesystem.  

  One problem you may have 'rm file' is very different from 'echo > file'
in that one unlinks the file so that it's inode is intact but not attached...
the echo on the otherhand truncates the file (releasing all the blocks 
that are part of the inode), and reuses the inode for the new file contents.
