Data duplication operations in storage networks |
摘要 |
<p>Exemplary storage network architectures, data architectures, and methods for creating and using snapdifference files in storage networks are described. One exemplary method may be implemented in a processor in a storage network. The method comprises receiving a request to execute a snapclone operation; generating, in response to the received service request, a snapclone copy of a source disk volume; contemporaneous with the generation of the snapclone file, opening a first snapdifference file; and recording I/O operations to the source disk volume in the snapdifference file. The methods described herein may be embodied as logic instructions on a computer-readable medium.</p> |
