Below is the error message I'm receiving. The master is running on OpenSUSE and my Jenkins version is "Jenkins ver. 1.466.12.1 (Jenkins Enterprise by CloudBees 12.11)".
I've verified that I can create a file on the linux box in /mnt/jenkinsbackup. Is this a user permission problem?

EDIT: I forgot to mention that I am running jenkins as a daemon and not as a user.
The permission problem stemmed from the mounted network folder. Only root had permission to write to it. One suggestion I found on the internet was to change the ownership of the folder to jenkins:nogroup (since that is what the Jenkins master is running as), but you can't do that to a mounted folder.
But that led me to changing the permissions when mounting the folder in the first place. I learned I could do this:
mount -t cifs //network_folder_path/jenkins /mnt/jenkins -o username=USERNAME,password=XXXX,dir_mode=0777,file_mode=0777
That mounted the folder with write permissions for everyone and the job was able to run.
