My current backup strategy can handle this. I never backup files from the source again if it didn't change by timestamp. That way, silent data corruption won't creep into the backup. Additionally, I keep a backlog of 5 years of file history. Even if a corrupted file creeps into the backup, there is enough time to get a good copy back. If it's older, it probably doesn't hurt so much anyway. -- Regards, Kai Replies to list-only preferred. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
