Continuous Cloud Errors - Lost Save Data

about the only thing you can try is to delete the local saves on the CONSOLE ONLY ( highlight the game from games and apps , press the menu button on the controller , select manage game , then saved data , then local or console only) after that go into
settings and remove all the profiles , (make sure you have the email and password to get them back ) after you remove the profiles , shut the xbox down by holding the xbox logo on the console for 8 seconds till it powers down , while it is off , unplug your
modem and router for 30 seconds to clear them also , plug the modem and router back up and when they are online , turn the xbox back on , when it is all the way up . re add your main profile ...it may sit there and sync a little while but all SHOULD be good
afterwards ...

It depends on the game really...if it has cloud saves, then your data won't be lost as it is in the cloud (all my games I was able to continue where I left off when I transferred consoles).

Games which only have local saves would require you to transfer the saves between consoles before wiping the XB1 (unless of course there is a way to cloud save)

You missed the point entirely.

Xbox Life Cloud Save continued syncing with my local Xbox One hard drive every time I started the game. The complete safe was never lost, otherwise the sync would have restored it.

When part of my information disappeared, the sync still happened, but treated the new version -- with the missing data -- as official, and overwrite the other save (that was not missing anything) with the one that was.

Cloud save worked to back up my save, but could not recognize that my save had mysteriously lost some data.

The simple answer is to sign out and resign in. That is typically the issue. Here's a link to cloud data. That said it could very well be a common server issue:

Hi Synthia,

What’s the specific game, or are multiple games affected? You might have some success recovering certain in-game content if you contact the developer.

If the save data was deleted locally, then everything should simply resync once you relaunch the game. If it’s the cloud save that was deleted, however, then there isn’t currently any solution.

It’s unfortunately not possible to recover any game save data/progress once it’s been deleted everywhere - this is permanent with immediate effect.

Similarly, if a game save is overwritten or corrupted, then the previous save would be lost and the only option would be to continue with the new one.

Also keep in mind that games and game progress are associated to your account/profile and not the device itself.

If you experience any issues trying to sync game save data, refer to:
