I have the same problem here.
I have made a backup with some files in a folder called /usr/test, in that i have 4 files called: test1,2,3 and 4.
When i delete them, no prob, but when i wanna restore the files i youse this command and get this error saying; “Restore Failed”
But if i make the “test” folder again, and youse the same command, i works fine? any idea?
