No Man’s SaveGame Manager

Source code available on bitbucket:


No Man's SaveGame Manager is a tool that runs in the background and will create backup copies of every savegame file that No Man's Sky creates. 

The motivation is to provide the ability to:

  • Be able to restore an older version in case your recent saves are all corrupted
  • Restore an older version of a savegame in case all recent saves are somehow problematic (e.g. you fell through the ground or are inside a building with a closed door and cannot get out)


Contact: In case you want to contact me for feedback, bug reports or suggestions chose one of the following ways:

Compiled binaries are not available any more. Please follow the link to obtain the source and build the toll yourself using a visual studio version of 2015 or newer. The free community edition will work. (Released 29.08.2016)
