Shahrbaraz is first mentioned when Khosrow II started the last and most devastating of the Byzantine–Sasanian wars, which was going to last 26 years.
Khosrow II, along with Shahrbaraz and his other best generals, conquered Dara and Edessa in 604, and in the north, the Byzantines were driven back to the old, pre-591 frontier before Khosrow II gave them most of Sasanian Armenia, parts of Mesopotamia and western half of the Kingdom of Iberia.
After reconquering lost territory, Khosrow II withdrew from the battlefield and handed military operations to his best generals.
Shahrbaraz was one of them.
In 610, Heraclius, an Armenian of probable Arsacid descent, revolted against the Byzantine Emperor Phocas and killed him, crowning himself as Emperor of the Byzantine Empire.
After becoming Byzantine Emperor, he prepared a major counter-attack against the Sasanians outside Antioch in 613, but was decisively defeated by Shahrbaraz, who inflicted heavy losses on the Byzantine army and then captured the city, giving the Sasanians naval access to the Mediterranean Sea.

After the Byzantine defeat outside Antioch, Heraclius and his brother Theodore, along with General Nicetas, combined their armies in Syria, but were defeated by Shahrbaraz and his forces who besieged Damascus and captured it along with a large number of Byzantine troops as prisoners.
Furthermore, Shahrbaraz also defeated a Byzantine army near Adhri'at, which is mentioned in the Quran.

One of most important events during his career was when he led the Sasanian army towards Palaestina, and after a bloody siege captured Jerusalem, a city sacred to the Christians.
After his conquest of Jerusalem the Holy Cross was carried away in triumph.
In 618, Shahrbaraz was ordered by Khosrow II to invade Egypt, and by 619, Alexandria, the capital of Byzantine Egypt, was in Sasanian hands.

After the fall of Alexandria, Shahrbaraz and his forces extended Sasanian rule southwards along the Nile.
By 621, the province was securely in Sasanian hands, and a certain Sahralanyozan was appointed as its governor.
In 622, Heraclius counter-attacked against the Sasanian Empire in Anatolia.
Shahrbaraz was sent over there to deal with him, but was eventually defeated by him.

After Heraclius' victory, he marched towards Caucasian Albania and wintered there.
Shahrbaraz, along with Shahin and Shahraplakan were later sent by the orders of Khosrow II to trap the forces of Heraclius.
Shahin managed to rout the Byzantine army.
Due to jealousy between the Sasanian commanders, Shahrbaraz hurried with his army to take part in the glory of the victory.
Heraclius met them at Tigranakert and routed the forces of Shahraplakan and Shahin one after the other.
After this victory, Heraclius crossed the Araxes and camped in the plains on the other side.
Shahin, with the remnants of both his and Shahraplakan's armies joined Shahrbaraz in the pursuit of Heraclius, but marshes slowed them down.
At Aliovit, Shahrbaraz split his forces, sending some 6,000 troops to ambush Heraclius while the remainder of the troops stayed at Aliovit.
Heraclius launched a surprise night attack on the Sasanian main camp in February 625, destroying it.
Shahrbaraz only barely escaped, naked and alone, having lost his harem, baggage, and men.

Heraclius spent the rest of winter to the north of Lake Van.
In 625, his forces attempted to push back towards the Euphrates.
In a mere seven days, he bypassed Mount Ararat and the 200 miles along the Arsanias River to capture Amida and Martyropolis, important fortresses on the upper Tigris.
Heraclius then carried on towards the Euphrates, pursued by Shahrbaraz.
According to Arab sources, he was stopped at the Satidama or Batman Su River and defeated; Byzantine sources, however, do not mention this incident.
Another minor skirmish between Heraclius and Shahrbaraz took place at the Sarus river near Adana.
Shahrbaraz stationed his forces across the river from the Byzantines.
A bridge spanned the river, and the Byzantines immediately charged across.
Shahrbaraz feigned retreat to lead the Byzantines into an ambu
