There have been some good suggestions.  I would use a large buffer with 
dd, say 1M or more, both for speed and to reduce the chance of hitting 
only part of the search string.

For the future, look at sysutils/rsnapshot.  Easy to set up, 
space-efficient, and provides an easily-accessed file history.
