Abstract:
A method for a storage system reduces data movement for snapshot copy-on-write operations. The method includes providing a live volume having snapshot chunks. Each snapshot chunk includes a number of deduplication chunks. Each deduplication chunk is mapped to a disk chunk on a disk. The method includes creating a snapshot of the live volume and, for each host write to a snapshot chunk of the live volume that shares a set of disk chunks with a snapshot, performing a snapshot copy-on-write operation by a using a deduplication operation.
