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 translation: 提供了执行拷贝卸载操作的方法和系统。 该方法包括在源数据容器被打开以进行拷贝卸载操作以将源数据容器从源位置复制到目的地位置之后，确定是否可以改变源数据容器的内容。 该方法还包括使用直接复制模式来生成用于拷贝卸载操作的令牌，而不需要基于源数据容器的模式来改变内容不能改变源数据容器的时间点 开了 并且当可以改变内容时，通过采取用于生成令牌的源数据容器的时间点图像来选择时间点复制模式。
