Cyber Recoverylla on kaksi koodipolkua, kun tehdään NetWorker-sovelluksen palautusta yhdellä Linux-palvelimilla ja toisella Windows-palvelimilla. Tässä tapauksessa palautuksen aikana se osoitti, että sovelluksen tyyppi oli Windowsin sijasta Linux.  Kun NetWorker-sovellus lisättiin, se ei saanut oikeita tietoja sovellustyypin määrittämiseen Windowsiin, vaan se oli Linux. Siksi /etc/hosts-tiedostoa varmuuskopioidaan cp -p:n avulla. Windowsin koodipolussa ei käytetä -p-vaihtoehtoa.
