摘要
Method for creating a consistent image, on a destination volume, of a target volume that remains in production use while the image is being created, without requiring the use of a snapshot, by copying the data on the target volume to the destination volume, maintaining changes to data blocks that arise on the target volume during copy operations, copying changed blocks to the destination volume, and repeating changed block updates as necessary until there are no further changed blocks on the target volume (all as more fully described in the specification).
