For anyone attempting to use
SyncToy + Task Scheduler + Mapped Networked Drives + Windows 7 and your scheduled backup fails because the networks cannot be found....
SyncToy must be set-up with an UNC path. Instead of using the 'Browse' button in SyncToy, open up cmd and type 'net use' and use the "Remote Name" instead of the mapped drive letter. For example, my result is below and I use \\FREENAS\robert_bak instead of M: now and it works great with the task scheduler.
Code:
Status Local Remote Network
-------------------------------------------------------------------------------
OK M: \\FREENAS\robert_bak Microsoft Windows Network
