CopyVolume

Contributors netapp-pcarriga amgrissino

You can use the CopyVolume method to overwrite the data contents of an existing volume with the data contents of another volume (or snapshot). Attributes of the destination volume such as IQN, QoS settings, size, account, and volume access group membership are not changed. The destination volume must already exist and must be the same size as the source volume.

It is best if clients unmount the destination volume before the operation begins. If the destination volume is modified during the operation, the changes are lost. This operation can take a variable amount of time to complete. You can use the GetAsyncResult method to determine when the process has finished, and ListSyncJobs to see the progress of the copy.
