Automatically log out and can't resume file uploading

I have uploading over 200 GB files to mycloud home via mycloud web overnight. However, it found that it will automatically log out after several times without manual control of Mac.

And, it is poor that there is no file uploading resume function and no asking of “skip / overwrite / duplicate new file” while there are existing files in the mycloud home folder. I make me double the files / folders.

Is there any setting to solve these problems?

Have you tried installing WD Discovery on the Mac and copying the files using the drive WD discovery mounts on the desktop?
