I am apparently running in Safe-Mode, which I am not. All the folders have write access.
Your backup program is also looking for:
Which I also do not appear to have. I do have folders labeled wp-admin, wp-content, and wp-includes

Many thanks.

OK. Problem solved. Found the backup folder but could not change the rights without deleting it first and recreating it. All backed up.

Next step is moving the backup to the cloud. Here goes.
