Backup to NAS devices
NAS or Network Share access rights are defined by the account of the accessing service(s).
Services can be
NBK DC Remote Command Executor
NBK DC Hiserv
NBK DC Backup Service
Apply an account to the service(s) which has local host admin rights and read/write access to the NAS (Share).
The account can be a domain account (if the NAS is part of the domain) or a local account which is also configured on the NAS (share) with identical password.
To change the service account open the services (start->run->services.msc) as administrator, navigate to the specific service, [right mouse]Properties, tab "Logon" and check "This account" and type the name of an account able to access the NAS properly as well as the password. Click [OK] and restart the service.
