Embodiments of the present disclosure provide a method and device for data duplication cutover. The method includes initiating duplication of initial data from a source device to a destination device, wherein the initial data are data of a file system stored on the source device upon the initiating. The method further includes, in response to completing the duplication of the initial data, updating a session associated with the file system. Furthermore, the method includes, after updating the session, triggering the source device and the destination device into a data unavailable state to perform duplication of delta data from the source device to the destination device, wherein the delta data are data of the file system changed during duplication of the initial data. Utilization of the cutover mechanism proposed in the present disclosure enables effective reduction of data unavailable period of time.

To monitor data duplication progress, embodiments of the present disclosure relate to a method and apparatus for determining data duplication progress in real-time. The method comprises initiating a duplication of data from a source system to a destination system. The method further comprises determining first duplication progress for an initial stage of the duplication, original data existing on the source system when the duplication is initiated being duplicated in the initial stage. Furthermore, the method further comprises determining, independently from the initial stage, second duplication progress for a delta stage of the duplication, delta data being duplicated in the delta stage and including at least data generated during the initial stage. The present disclosure develops a fine-grained monitoring mechanism of data duplication progress.

The present invention discloses a household vacuum sealer and a bag-cutting sealing method. In the household vacuum sealer, at least one cutter device is slidably mounted on the upper hood, a heat-seal bar and an evacuative groove are arranged at the front side of the upper portion of the lower hood, the upper hood or the lower hood is provided with a bag receiving chamber, a detachable automatic rollback shaft is rotatably mounted in the bag receiving chamber, the elastic rollback mechanism for automatically rolling the rollback shaft back and the elastic unidirectional locking mechanism for locking the automatic rollback shaft are mounted at the end portion of the automatic rollback shaft; the cutter device protrudes from a bottom surface of the upper hood, and the cutter moves at one side of the heat-seal bar or one side of the evacuative groove back and forth after the upper hood is locked onto the lower hood, for cutting off the bag pressed tightly between the upper hood and the lower hood. The present invention has a simple structure since the bag is cut at the original heat-seal bar or the evacuative groove of the lower hood, which is more convenient. Subsequent to cutting off the bag, the vacuum packaging bags are automatically rolled back after the hood is opened, which reduces the number of operation steps for the user, and exhibits ease and quickness of operation.
