> Neat, Zach. You should look at xfs_copy - it does pretty much this for XFS > filesystems.... haha, yet another round of the -fsdevel XFS drinking game :) Does xfs_copy tend to assert the XFS file format in the backup files it generates? One of the things I was hoping for with bdar was to have the resulting copy image be agnostic. It's just a sparse map with some checksumming, really. That limits what we can do, of course. The current trivial format only has one address space which doesn't fit well with the plans file systems have of working with multiple addressable block ranges. But I think I'm fine with that. The value:complexity ratio of this trivial version is refreshingly large. - z -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
