CLONE VOLUME MERGING

摘要

One or more techniques and/or systems are provided for clone volume merging. For example, a parent volume may be exposed to users for read and write access to data stored within the parent volume. The parent volume may be cloned to create a cloned volume of the parent volume. The cloned volume may be exposed to users for data access. Responsive to receiving a clone volume merge command, data blocks within the cloned volume may be compared with data blocks within the parent volume to identify delta data blocks within the cloned volume that are not within the parent volume. The delta data blocks may be copied from the cloned volume to the parent volume, which may increase performance and/or decrease time taken to generate a volume with both common data blocks and the delta data blocks, as compared to copying data from the parent volume to the cloned volume.

主权项

1. A method for clone volume merging, comprising:
cloning a parent volume to create a cloned volume of the parent volume; facilitating data access to the cloned volume resulting in delta data comprised within the cloned volume, the delta data not comprised within the parent volume; comparing data blocks of the cloned volume and data blocks of the parent volume to identify delta data blocks corresponding to the delta data; and copying the delta data blocks from the cloned volume to the parent volume.
