You aren't using the IF ERRORLEVEL test correctly. IF ERRORLEVEL nn 
evaluates as true if the errorlevel is equal to OR GREATER THAN 
nn. "if errorlevel 0" will always evaluate as true because errorlevel 
will always be greater than or equal to 0.

The usual way to carry out the above is to test in the negative.
if not errorlevel 1 (
Echo Copied successfully %%i >>archivesuccess.log
) else (
Echo Error occured for %%i >>archiveerr.log
) 

Since you're using NT or above, you can also do this:
if %errorlevel% EQU 0 (
Echo Copied successfully %%i >>archivesuccess.log
) else (
Echo Error occured for %%i >>archiveerr.log
) 

Also, you need to be aware that Xxcopy sets the errorlevel to 100 if 
no files were found to copy and to 100+no_of_failed_copies if the 
copy succeeded but there were some failed copies.

You can either use the /ER switch to change the error codes to be 
xcopy compatible (see XXTB #31) or also test for the errorlevel 100 
case (see XXTB #19). You might write your test like the following:

if %errorlevel% NEQ 0 if %errorlevel% NEQ 100 (
Echo Error occured for %%i >>archiveerr.log
) else (
Echo Copied successfully %%i >>archivesuccess.log
)
