Each snapshot is completely independent. This works because data which is shared between multiple snapshots is reference counted, and won't be deleted until you remove the last snapshot that references that data. -- Calvin Walton <calvin.walton@xxxxxxxxxx> -- 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
