Hello

Save data for the Xbox One is actually saved on both the harddrive and the cloud, if you move all your content to an external drive it should be moved to that drive as well but the cloud data stays where it is.

If however you should lose your local save data, the next time you boot up the game it will ask you to upload local data or download your save from the cloud. When you click download you will have a copy as local data again as well as cloud based.

No, redownloading the games will not affect his save data, the save data is saved to the cloud, and is not deleted.

Hello SPECTRE_KENNEDY,

Thank you for keeping up with us. The option to clear local saved data removes saved data from the console itself. As long as the console has a connection to Xbox Live, saved games are automatically stored in the cloud. If you have any games that you have
played while offline, we recommend going online with those games to upload the saved data to the cloud. Once all you saved data is secured on the cloud, we suggest clearing the local saved games. Sometimes an account may have trouble with collecting the saved
data from the cloud. This is where clearing local saved games can help. The option to clear local saved games will re-sync the saved data from the cloud to your account. We hope this helps!
