Considering i do not use wordpress, im trying to help though.
if you are referring to trying a restore from a file that was saved in
that "wp/wp-content/uploads/backup" directory, i doubt you can.
not unless you had some restore extension/feature in wordpress to do that.
which i do not know if you do.
its possible you would get a better answer on wordpresses support website,
as this isnt generally a x10hosting support question,
unless there is another member with with wordpress who can help with this.
