What is the efficient way to backup large files?
===

I have the schedule job of backing large files in Windows Server and it takes almost 2 hours to finish.

For now, I only use copy command in the .bat and copy the large files to another folder.

I'm wondering whether there is more efficient way than the copy command to backup the large files(approximately 90GB). For example, write an c++ program to copy the files rather than the copy command.

Many thanks.
