Elements 2021 windows 10 backup error

While doing full backup of photo library following error message recieved, 'Error encountered while writing file(s) E:\Volumes\my passport\Organizer\Photo Library Media\Masters\2012\11\06\20121106-151740\Img\Img_0382.Jpeg.

The backup seems to have completed but I do not know for sure, is there any action I need to take please?
