This parameter defines the command to read data from remote tape devices.
copy_in_cmd = <cmd>
Default value: none
You must enter a value before you switch to “remote piping”, that is, backup_dev_type = pipe|pipe_auto|pipe_box.
This parameter specification is only useful in combination with parameters remote_host and remote_user for reading from remote systems.
copy_in_cmd = "dd bs=64k if=$",
However, you can also use higher blocking to improve performance. The $ character is replaced by the device address. Do not forget to enclose the parameter specifications composed of several values in double quotes.
