Unix is not a MSDOS. Filename *.* does not have the same meaning in unix as MSDOS and can cause you to miss files. In your case it will miss directories unless the directory name contains a full stop character.
The command sequence posted may be nearly giving the right results by accident. it is however not correct.
After re-reading your post several times I am not 100% clear what you are trying to do.
Are there any subdirectories under /dev/data ?
Are there any files directly under /dev/data ?
If there are subdirectories, do you you want to replicate that tree under /isdev/data/history ?
If so you should really be looking at unix "cpio -p" not "cp -R". This will also address your problem of "cp -R" creating the directory tree one level down.
For example (but do check your local "man cpio").

How can we copy a command string from a previous command line and paste it into the cursor position on the current command line? I know that ^c will not work as the shell will interpret as an interrupt signal.

LEARN ABOUT PHP
passthru
PASSTHRU(3) 1 PASSTHRU(3)passthru - Execute an external program and display raw outputSYNOPSIS
void passthru (string $command, [int &$return_var])
DESCRIPTION
The passthru(3) function is similar to the exec(3) function in that it executes a $command. This function should be used in place of
exec(3) or system(3) when the output from the Unix command is binary data which needs to be passed directly back to the browser. A common
use for this is to execute something like the pbmplus utilities that can output an image stream directly. By setting the Content-type to
image/gif and then calling a pbmplus program to output a gif, you can create PHP scripts that output images directly.
PARAMETERS
o $command
- The command that will be executed.
o $return_var
- If the $return_var argument is present, the return status of the Unix command will be placed here.
RETURN VALUES
No value is returned.
NOTES
Warning
When allowing user-supplied data to be passed to this function, use escapeshellarg(3) or escapeshellcmd(3) to ensure that users can-
not trick the system into executing arbitrary commands.
Note
If a program is started with this function, in order for it to continue running in the background, the output of the program must be
redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.
Note
When safe mode is enabled, you can only execute files within the safe_mode_exec_dir. For practical reasons, it is currently not
allowed to have .. components in the path to the executable.
Warning
With safe mode enabled, the command string is escaped with escapeshellcmd(3). Thus, echo y | echo x becomes echo y | echo x.
