Which of the following is part of the remote protection policies in System Manager?

Asynchronous replication is a key component of remote protection policies in System Manager because it allows data to be copied from one storage system to another at scheduled intervals, ensuring data consistency and availability across different geographical locations. This methodology is essential in disaster recovery scenarios, where an organization's data needs to be safeguarded against potential loss or corruption due to site-specific issues.

By utilizing asynchronous replication, data can be moved in a non-real-time manner, which can help minimize bandwidth usage and impact on performance while still ensuring that the secondary site has up-to-date information. This approach balances the need for data recovery with operational efficiency, making it a preferred choice for many organizations looking to implement effective data protection strategies.

The other options—data scrubbing, data compression, and snapshot scheduling—while they may play important roles in overall data management and protection strategies, are not focused specifically on remote data protection policies. Data scrubbing is about maintaining data integrity, data compression reduces storage requirements without serving specifically to protect data remotely, and snapshot scheduling deals with creating point-in-time backups rather than facilitating remote replication. Therefore, asynchronous replication stands out as the core feature related to remote protection policies in System Manager.
