CrashPlan doesn't support backing up mapped drives on Windows. CrashPlan runs as a Windows service and therefore cannot access drives mounted by a user. This is an OS-level restriction built into Windows.
If you would like to back up a mapped drive on Windows, this article describes an unofficial method for doing so. It is not supported by CrashPlan or Code42, so proceed at your own risk.
This method for backing up a mapped drive requires advanced knowledge of Windows. It is not for beginners. If you don't feel comfortable using a command line, you should stop now.
The key element of the net use command is the /USER:ip\username syntax. Without the IP (or desktop name if Windows) it does not work.
The raw command is provided below (replace contents inside angle brackets and remove the angle brackets):
net use S: \\<device_ip_address>\<share_name> /USER:<device_ip_address>\<username> <password> C:\tmp\mount.log 2>&1 2>&1
Sample File Contents:
echo %date% %time% : "%cd%\mount.bat" >> C:\tmp\mount.log >&1 2>&1 net use S: \\10.10.42.50\plindqui /USER:10.10.42.50\plindqui <password> >> C:\tmp\mount.log 2>&1 2>&1
Note: If you create your batch file in Notepad, make sure you select All Files from the Save as Type menu. Otherwise, Windows interprets your batch file as a regular text file.
Now that you have your batch file, create the task on XP:
When you sign in with your Owner account you can see a network mapped drive that you don't have permission to read. It appears as disconnected. The “disconnected” drive is the mapping CrashPlan will be using.
In the CrashPlan destination / source file browser:
(optional) Of course, you can map it with your Owner account, so you can interact with the files. In this case the two mappings are both valid:
For Vista, the batch file remains the same, but the steps to create a scheduled task are different.
