If I make a cow copy of a file, is there a way find out whether either copy has changed? Specifically, I'm looking for a way to figure out which files have changed since a snapshot was taken, short of traditional and time-consuming file comparisons. It could have some interesting possibilities for monitoring and backup, to be able to quickly compare against a reference snapshot to find changes. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
