after doing a system restore, can you get your saved data back?

Answer 1

A system restore may have erased later downloads. See below

If you do a system restore, you could lose a lot of information, not to mention that it is no guarantee of ridding yourself of malware. See the article below (first link) from a Microsoft MVP.

"System Restore should only be used after trying less comprehensive methods of troubleshooting. System Restore changes many files and registry entries, and in some cases might replace more files than you want restored."

The second link below is also from Microsoft. If you look through the Q&A, you'll see reference to the following

"System Restore does not completely uninstall any program if restoring to a point prior to the program installation. As System Restore is based on an inclusionary model, any files added or modified by the installation (which is not monitored by System Restore) or added to or modified in a non-monitored drive will not be tracked. To remove all changes an installation may have made to the system, the user should first use the Add/Remove option in the control panel to remove the application prior to using System Restore. System Restore will undo all recorded changes made to the registry and monitored files caused by the application install, including:
• Deleted or monitored files added to the system from the program installation
• Undo modifications to monitored files made by the installation
• Replacement of the current registry with the registry snapshot taken at the chosen restore point (some current values may persist)"

Answer 2

If you're talking about the System Restore that you use up there in the Start panel then, a System Restore won't mess with your data! So don't worry! All that System Restore does is restore the "registry" with is the little "notepad" in which Windows keeps track of the large batch of system settings, program registrations, who's who, what's what, when's when, and like that. Your data will all be there when you get back.

Answer 3

yes, you can get your saved data, because the system restore will lose only the software that you installed recently.
data will be there forever.
