    Abstract: Methods and systems for executing a copy-offload operation are provided. The method includes determining if content of a source data container can be changed, after the source data container is opened for a copy-offload operation to copy the source data container from a source location to a destination location. The method further includes using a direct copy mode for generating a token for the copy-offload operation, without taking a point in time image of the source data container, when the content cannot be changed based on a mode in which the source data container is opened; and selecting a point in time copy mode by taking the point in time image of the source data container for generating the token, when the content can be changed.

    Abstract: Methods and systems for a copy-offload operation are provided. A soft range lock is placed for a data container for generating a token for a copy-offload operation for copying the data container from a source location to a destination location, where presence of the soft range lock indicates that content of the data container has not changed during the copy-offload operation. A token for the copy-offload operation represents the content of data container and includes information regarding the soft range lock. The token with the soft range lock information is provided to the client that requests the copy-offload operation. If the soft range lock exists, then the data container is copied without using a point in time copy of the data container.
