....Dumbledore tells Harry at the end of PoA that since he spared Peter Pettigrew's life, that Peter was indebted to Harry, and in DH he showed a moment of mercy to Harry at Malfoy Manor. Dumbledore also stated that when a wizard saves another wizard's life, the act itself evokes a bond between them: "This is magic at it's deepest, it's most impenetrable". If this is true, then wasn't Snape indebted to James in the very same way since James saved his life when they were students at Hogwarts?
....Do any other characters in HP have life debts to each other; and if so, when/how was this magic evoked? How is this "bond" realized, and can this deep magical bond be broken somehow?
I have considered that possibly the invocation of the life debt has something to do with how much one is actually saved from certain death. James surely prevented Snape from encountering a situation that had the potential to kill him, but Snape was not facing
certain death; he could just as likely have been injured by werewolf Lupin but not killed, or he could have even escaped before Lupin could get to him. Indeed Lupin says that Snape glimpsed him before James pulled him back, so both James and Snape made it to the end of the tunnel and saw the werewolf and still escaped. Maybe just saving someone from something that has deadly
potential isn't enough to invoke the life debt. Similarly, Harry didn't so much save Dudley's life, he saved him from the Dementor who would have sucked out his soul, which wouldn't have killed him. In contrast, Lupin and Sirius had their wands raised and were seconds away from killing Peter when Harry intervened, so I think Peter
was facing certain death and Harry saved him. Having said all that, I agree with
The Crimson Artist that there are probably many situations throughout HP where one character saves another's life, even from certain death. In the case of the trio, they probably ended up repaying these debts to each other throughout the course of the series, but like
SeveraSphyrna said, imagine all of the instances of comrades saving each others lives throughout wartime! Who knows if all of those debts are repaid....

My immediate thought was that Snape redeemed himself in Deathly Hallows and all Harry's time at Hogwarts by saving Harry eg, the episode on the broomstick in his first year.

....If somebody saves your life, then you feel indebted to them. I think this is quite important in some cultures, where the person who is rescued believe they really owe their rescuer. They're not happy til they've returned the favour somehow. This would fit in with what Dumbledore says about Snape in PS, that he couldn't bear being in James' debt, and he protected Harry during his first year so that he and James would be even.
I had thought that the comment from Dumbledore about Snape repaying James by saving Harry from falling off his broomstick was just a cover for the truth: that Snape had pledged to protect Harry in order to honor Lily's life. Dumbledore promised Snape that he would never tell Harry this, so I figured that he used this story about paying James back to satisfy Harry's curiosity.
I had been waiting throughout the series for when this whole life thing debt was going to come back into play, based upon how much importance Dumbledore seemed to give it in SS/PS, and was a bit let down at how it played out. I was expecting some more obvious "magic" to prevent Peter from doing harm to Harry. By the time we see the graveyard scene in GoF, that idea went out the window. I wondered if somehow JKR had just dropped the whole thing.

Dumbledore's statement that it's a form of magic complicates all this though. But then Dumbledore said that love was a magical force, one that was studied in the department of mysteries, that Harry had it in such abundance as to make it important in defeating Voldemort. The only time we see love have a genuine magical effect is with Lily's sacrifice protecting Harry. I don't really remember Harry's love having any magical effect though, so I've never really understood what Dumbledore was talking about wrt love either.
Maybe Dumbledore was just a bit crazy. Cos from what we actually see, and ignoring that thing that Dumbledore said but which we don't really see evidence of, it seems a straightforward matter of wizards having a strong sense of honour when it comes to repaying a life debt.
I think you've hit upon something here,
Wendall. Dumbledore's statement of "This is magic at it's deepest, it's most impenetrable..."(PoA p.311 UK paperback) sounds reminiscent of the way Dumbledore speaks of the power of love; I think it is possible that this is what Dumbledore was referring to in this statement. When Harry chose to save Pettigrew's life, it was an act of love; he chose love instead of hate. He thought of his father and his father's love for his friends, and that James would not have wanted his friends to become killers. His love for his father won out over his hatred of Pettigrew. Even if he saved him for love of his father and not for love of Pettigrew, it was still an act of love. Dumbledore says, "When one wizard saves another wizard's life, it creates a certain bond between them..."(PoA p.311).
Perhaps mercy creates a bond borne of love. Voldemort, an enemy of this power, cursed Peter's hand to destroy its owner if it detected any such mercy within. It is not a quality that he would want in a Death Eater.
