Default Backend

By default, UMI uses SaveBackend_File which saves to disk: 
ProjectDir/Saved/SaveGames/
├── SaveSlot_001/
│   ├── Players/
│   │   ├── player_guid_1.sav
│   │   └── player_guid_2.sav
│   └── World_Containers/
│       ├── container_guid_1.sav
│       └── container_guid_2.sav

​
Custom Backend

Implement ISaveBackend for custom storage: 
class ISaveBackend
{
public:
    virtual bool SaveRecord(const FString& Bucket, const FGuid& Guid, const FSaveRecord& Record) = 0;
    virtual FSaveRecord LoadRecord(const FString& Bucket, const FGuid& Guid) = 0;
    virtual bool DeleteRecord(const FString& Bucket, const FGuid& Guid) = 0;
};
Example Use Cases:
  • Cloud saves (Steam, Epic, Console)
  • Database storage
  • Encrypted saves
  • Compressed saves
