What type of replication is used for immediate data transfer in System Manager?

Synchronous replication is the correct choice for immediate data transfer in System Manager because it allows data to be written simultaneously to both the primary and secondary storage systems. This process ensures that the data is consistent across both locations at the same moment. It is primarily used for operations that require real-time data availability and zero data loss, making it suitable for scenarios where immediate data accessibility is critical, such as in financial transactions or data processing applications.

In contrast, asynchronous replication involves transferring data to the secondary storage after it has been written to the primary system, which may introduce a delay. Scheduled backup refers to periodic backups at set intervals, rather than real-time replication. Snapshot replication is designed for creating point-in-time copies of data rather than continuously synchronizing data between systems. Thus, while those methods serve various purposes, they do not facilitate immediate data transfer as effectively as synchronous replication does.
