If you get a message "Medium not found" check if the medium was inserted at the time of the backup start.
On some systems the NovaBACKUP backups to RDX drives terminate after a few seconds. In the log you find the message that the medium could not be found. This message can have several causes:
1. No medium inserted
Possibly no medium was inserted at the time of the backup start.
2. Power saving mode for RDX drive active
It can also happen that a RDX drive goes into power save mode and takes too long to wake up. Turn off all power saving modes, even in the options for the USB ports.
3. Media change is not passed to NovaBACKUP
On some systems it can happen that NovaBACKUP (NBK) does not recognize the external drives or media after a change. The backup will abort immediately, no data will be saved. In such cases you can stop/restart the nsservice shortly before the backup (15 minutes) via Windows scheduling. Thus it reads the drives again:
net stop nsservice
net start nsservice
Save the above commands in a batch file (e.g. nsservice_restart.bat) and start it via Windows Scheduling approx. 15 minutes before the backup.
On some systems you have to do this with Powershell:
powershell -command "Restart-Service nsservice -Force" -PowerShell
Save this as Powershell file (e.g. nsservice_restart.ps1) and start it via Windows Scheduler approx. 15 minutes before the backup starts.
You can NOT use these scripts as pre/post scripts because you stop the NovaBACKUP services
