I have versioned backups for a few months. Most people don't and can't (it requires a lot of storage)
Even if they have them, the diffing needs to be done.
Given the past problems with ZFS, I think I'll write a summarizer, that creates a database of metadata for each backup: it will be small to keep around, and may be use more easily to determine which backup contains the uncorrupted file.
