Since he's a sand-mage he most likely conjured up a shield of sand.

Here in the 2nd to left bottom frame you can see something that to me looks like a few specks of sand floating between the dissipating Jupiter energies and the ship. It might be a bit of detail from the ground coming through, but I think it's remaining particles of his sand-shield.

But instead of making it a wall-like barrier, he probably shaped it like a wedge to turn the energy aside, rather than stopping it head-on. Pretty smart to protect his own ships but not to smart if he cared about the other 40 or so ships that got annihilated.
