If you want to keep it in history as failed attempt, just commit and then 
backout. 

$ hg commit -m "Attempt to solve X"
$ hg backout tip

If you want to only keep a backup which doesn't appear in history, just 
commit, clone the repo away and then rollback and "update -C". 

$ hg commit -m "Failed attempt to solve X"
$ cd ..
$ hg clone project failed-attempt-to-solve-x
$ cd project
$ hg rollback # undo the commit
$ hg update -C # update all files to the last committed version. 

Backout has the advantage, that you can also backout of many changes, while 
rollback only undoes the last one ("clone -r GOOD_REV" can fill the role, 
though). 

Best wishes, 
Arne
