When you use Advanced Copy function, to assure data consistency, please confirm that there isn't any access to a business volume.
However, for more secure consistency, it is recommended to stop the server connected to the business volume.
When you can't stop the business server, unmount the business volume by the server's OS command and reflect the data from the file cache and stop the access to file cache.
For the unmount command, refer to each OS's manual.
