    Abstract: A method and software is described for recreating on a target datastore a set of hierarchical files that are present on a source datastore. A content identifier (ID) is maintained for each component of the set of hierarchical files. The content ID of a component is updated when its contents are modified. The child component is copied from the source datastore to the target datastore. The content ID corresponding to the parent component on the source datastore is compared with content IDs corresponding to files present on the target datastore. When a matching content ID is discovered, it infers a copy of the parent component. The matching file on the target datastore is associated with the copied child component so that the matching file becomes a new parent component to the copied child component, thereby recreating the set of hierarchical files on the target.

    Abstract translation: 描述了一种方法和软件,用于在目标数据存储上重新创建存在于源数据存储上的一组分层文件。 为分层文件集合中的每个组件维护内容标识符(ID)。 当其内容被修改时,组件的内容ID被更新。 子组件从源数据存储复制到目标数据存储。 将与源数据存储上的父组件相对应的内容ID与对应于目标数据存储上存在的文件的内容ID进行比较。 当发现匹配的内容ID时,它会推断父组件的副本。 目标数据存储区上的匹配文件与复制的子组件相关联,以便匹配文件成为复制的子组件的新父组件,从而在目标上重新创建一组分层文件。

    Abstract: A method for migrating a virtual machine disk (VM disk) from first physical storage to second physical storage while the virtual machine (VM) is running, the method comprising: (a) creating a first child VM disk to which writes are redirected from a first parent VM disk, the first parent VM disk being on the first physical storage; (b) copying the first parent VM disk to the second physical storage as a second parent VM disk; (c) re-parenting the first VM child disk to the second parent VM disk; and (d) consolidating the first child VM disk and the second parent VM disk.
