I only modified the relevant files on the target drive.
Is there a way to extract only the updated files from one drive and move them to a backup? It might involve a tool or script that can handle this automatically.
Some commands include flags for copying just updated files. You might also use Teracopy to overwrite only newly changed items. Both options can be set up automatically.
