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.
