I cannot restore a backup

[Kujakatti]

I mada an backup of my data from Xpreria Z3 Tablet compact to an USB memory with "Backup & Reset". Now after I mede a "Factory data reset" to my device,  I can not restore that data. "Restore data" finds the backup. I can choose "Email accounts", "Wi-Fi networks", "Device Settings", "Aplications" and "Xperia Home layout", but after tabing "Restore Data", nothing happens.
