Does Cuju guarantee consistency between checkpoints and shared persistent storage? about cuju

Actually, we use shared storage for primary and secondary VM and only primary VM can write the storage. And we buffered disk write operations when the memory state was not fully backed up to the secondary side.
In other words, when backed up finished, we release the buffered disk write operations to the shared storage. So it can make the shared storage state consistent with backed up state
