Introduction to protected groups of the OceanStor ReplicationDirector

2

Protected groups are service objects that are protected by the disaster recovery management system. Protected groups consist of protected objects and protection policies. You can create protected groups for various protected objects such as databases, local host file systems, LUNs, NAS file systems, and VMs. Select different protection policies to implement disaster recovery based on RPO/RTO requirements.

Introduction to the OceanStor ReplicationDirector host and host group
In OceanStor ReplicationDirector, a host refers to an application server deployed at the production site or disaster recovery site. A host protected at the production site is called a production host, and a host used for testing or disaster recovery at the disaster recovery site is called a disaster recovery host. A host group is a collection of one or more hosts of the same type.

Which status may a protected group of the OceanStor ReplicationDirector be in?
A protected group of the OceanStor ReplicationDirector (mainstream version: V100R003C10) may be in one of the following statuses: 1. Normal: indicates that the protected objects in the protected group are under protection. 2. Disabled: indicates that the protected group is disabled. 3. Invalid: indicates that the protected group is not under protection because its protected objects have been modified, for example, storage devices are changed or the synchronization between two ends fails. In addition, after a protected group switchover, the protected group changes to the invalid state. 4. Locked: indicates that a migration is being implemented for the protected group as specified in the recovery plan and no operation can be performed on the protected group. 5. Executing: indicates that the protected group execution has been automatically or manually triggered and data is being synchronized.

Introduction to OceanStor ReplicationDirector in the local protection disaster recovery solution
The local protection disaster recovery solution uses snapshot technology to ensure local availability of host services. This solution can use VIS snapshots of protected objects to roll back data, preventing data loss and virus attacks. The OceanStor ReplicationDirector Server is installed on the DR management host deployed in the production center and the OceanStor ReplicationDirector Agent is installed on production application hosts to ensure DR data consistency. This solution supports the snapshot (array and VIS) technology.

Introduction to OceanStor ReplicationDirector reprotection
If planned migration or fault recovery has been performed for a recovery plan, you can implement reprotection for the recovery plan. Reprotection protects data at the disaster recovery site once devices at the production site recover from disasters, simplifying failback. This operation can be performed only in the disaster recovery management system at the disaster recovery site.

Introduction to sites of the OceanStor ReplicationDirector
Resources in a disaster recovery management system are organized by site. You can configure disaster recovery services at a site or between sites. Create a local or remote site based on the disaster recovery network mode (local or remote). Sites are categorized as local sites and remote sites by location. - Local site: a site managed by the local OceanStor ReplicationDirector server. - Remote site: a site managed by the remote OceanStor ReplicationDirector server. Sites are categorized as production sites and disaster recovery sites by protection relationship. - Production site: a site where a production system resides. Service systems of enterprises run at the protected production site. - Disaster recovery site: a site where a disaster recovery system resides. The disaster recovery site provides backup and disaster recovery for the production site. If a disaster occurs, the disaster recovery site can be used to recover services.
