Hello, dear!
Have a nice day!
InfoReplicator
The InfoReplicator feature of the OceanStor 9000 V5 storage system supports asynchronous remote replication specific to directories. Folders or files can be automatically and periodically or manually replicated between multiple OceanStor 9000 V5 storage systems through IP links over a local area network (LAN) or wide area network (WAN).
The remote replication-based data recovery goes through the following phases:
Data of the primary storage system is periodically or manually replicated to the secondary storage system.
When the primary storage system is faulty, access requests from upper-layer applications are failed over to the secondary storage system.
When the primary storage system recovers, access requests are failed back to the primary storage system.

InfoStamper
Storage Networking Industry Association (SNIA) defines a snapshot as a point-in-time copy of a defined collection of data. Such a copy contains a static image of the source data at the copy point in time. Snapshots can be used for production testing, data backup, and data recovery.
The InfoStamper is a directory-based snapshot feature provided by OceanStor 9000 V5. It can create snapshots for any directory (excluding the root directory) in a file system instantly, enabling users to back up critical data without affecting services.
In addition, the OceanStor 9000 V5 can periodically create snapshots for source data. A periodic snapshot policy enables the OceanStor 9000 V5 to create data copies that preserve the state of source data at multiple points in time, providing continuous protection for the source data.
