Climbing to cruise altitude Right Bleed EICAS Message followed by a Left Bleed EICAS message. Resulting in loss of both PACKS.  Resulting is CABIN ALT warning message.  We began descent to 10;000 while preforming QRH procedures.  Landed safely.
Following the loss of both packs due to right and left engine bleed air failures the flight crew of a B757 diverted to a nearby airport and landed safely.
