When you open an existing analysis, Scenario
360 makes a backup copy of the analysis. It
places this backup in the analysis folder 
~Backup folder.
This folder
contains the last saved copy of your analysis and exists to enable automatic
analysis backup of key
analysis files. Additional
backup folders may be placed in subfolders within the analysis folder
to enable subfolder backup. You
can open this backup file in the case that your analysis becomes corrupted
or unusable. Simply
launch Scenario 360, choose to open
an existing analysis, navigate to your analysis backup folder and
open the backup analysis.
Upon closing a Scenario 360 analysis, you are given the opportunity to save changes or discard changes up to the last saved copy of the analysis. If you choose to close an analysis and discard changes, working copies of the analysis will be replaced with the backup copies.
