Snapshot data transmission method and device

The invention relates to a snapshot data transmission method and device, and the method comprises the steps: determining the available bandwidth of a snapshot task as a first available bandwidth whenthe data size of snapshot data corresponding to the snapshot task is smaller than a snapshot data size threshold value; and before a flow control feedback result is received, sending first snapshot data corresponding to the snapshot task according to the first available bandwidth, wherein the first snapshot data is snapshot data corresponding to the snapshot task. According to the snapshot data transmission method and device provided by the embodiment of the invention, the creation efficiency of snapshots with small data volume can be improved. 本申请涉及一种快照数据传输方法及装置，包括：在所述快照任务对应的快照数据的数据量小于快照数据量阈值时，确定所述快照任务的可用带宽为第一可用带宽；在接收流控反馈结果之前，根据所述第一可用带宽传输所述快照任务对应的第一快照数据，其中，所述第一快照数据为所述快照任务对应的快照数据。根据本申请实施例提供的快照数据传输方法及装置，可以提高小数据量的快照的创建效率。
