Add flag for restore

[botanicvelious]

Added a flag to decide if to restore or not, we were restoring/saving cache and it kept growing in size

Should be ready to go, let me know if there is anything you want changed.

updated it so it uses return;

Also I moved the stats printing so that you still get stats even when save=false no reason not to print stats
