摘要:
Methods and apparatuses for performing simplified copy offload operations are provided. In one exemplary embodiment, a method includes creating a persistent point-in-time image of a data set of a source storage device in response to receiving a token request for a copy offload operation from a host. Creating the persistent point-in-time image includes generating pointers to data blocks of the data set, but does not include duplicating the data blocks. The method also includes transmitting a token that is a representation of the persistent point-in-time image to the host in response to the request.
