Phone backup to WD MyCloud

I am trying to save space on my hp and trying to copy the photos from the phone to mycloud home. Each time I log into MCH, it will try to sync a copy of my hp photos to a folder in MCH.

I am wondering through this action, can I then delete away the photos from Hp to save my space? Will my photos that has been backup still remain on MCH or will it disappear if I delete it away from my hp at the next sync?

Am getting confused as to how to use McH to store my photos so as to release space from my hp which is getting quite full. Any advise is appreciated on how I could store the hp photos on MCH to save my hp space. Is the backup copy the right way? Thanks for advise
