D-Link Document - User Manual purpose of threshold could prevent the incremental copy failure immediately when running out of the snapshot space. For example, the default threshold is 50%. The system will check the snapshot space every hour. When the used snapshot space is over 50%, the system will start the clone job automatically. And then continue monitoring the snapshot space. When the rest of the snapshot space reaches 50%, in other words, the total snapshot space that has been used reaches 75%, the system will start the clone job again. Restart the task an hour later if failed: The setting will be effective after enabling schedule clone. When running out of the snapshot space, the virtual disk clone process will be stopped because there is no more available snapshot space. If this option is checked, the system will clear the clone snapshots in order to release snapshot space automatically, and the clone task will be restarted after an hour. This task will start a full copy. Clear Clone To clear the clone job, please follow the procedures. 1. Select the source virtual disk, and then click ▼ -> Clear Clone. 2. Click OK button to clear clone job. Clone Constraint While the clone is processing manually, the increment data of the virtual disk is over the snapshot space. The clone will complete the task, but the clone snapshot will fail. The next time, when trying to start clone, you will get a warning message "There is not enough snapshot space for the operation". The user needs to clean up the snapshot space in order to operate the clone process. Each time the clone snapshot failed, it means that the system loses the reference value of incremental data. So it will start a full copy at the next clone process. When running out of snapshot space, the virtual disk clone procedure will resemble following diagram. Copyright@2014 D-Link System, Inc.
