More Information
Summary:Methods and apparatus for point-in-time volumes are provided. A relationship is enabled between a source volume and point-in-time volume. Copying a data chunk to the point-in-time volume before a write operation modifies the data chunk on the source volume dynamically creates the point-in-time volume. The point-in-time volume can be accessed in read/write mode as a general purpose data storage volume. Other embodiments comprising additional features, such as a forced migration process, are also provided.
