Check if all data it was well copy

[mahesh]

Hi guys,

Exist another secure way to copy data between discs on server ubuntu beyond the command "cp -arvp /home/user/disk1/ /home/user/disk2/"?

Because after copy all data I checked if all data it was copy through command "du -sh folder/" and button right and properties (see report on the file manager, in this case the nautilus) and sometimes the result don't match between source and destiny (both the number of files and the disk space).

Thanks
