Hi all, I have a backup strategy in place where I use snapshots to determine the difference between yesterday and today. I then copy those blocks that have changed to a target machine and apply the difference to a remote copy of the entire block device. Currently this involves doing a complete comparison between a logical volume and its snapshot to find the blocks that have changed. I know that internally, LVM already has the information about which blocks have been altered -- these are what are stored in the snapshot after all. Is it possible for me to get that information somehow? Some pointers getting me started on this would be of great help to me -- especially if theres a simple way to do so already in place before I go delving into source code etc...
