Manage site disaster recovery

ARM hosts do not support disk backup-based disaster recovery. Disk backup-based disaster recovery is not supported in the following scenarios: Primary/backup switchover is performed on the management platform. The cluster does not contain a management node.

 

Site recovery manager (SRM) provides service recovery across different sites. With SRM, you can configure UIS Manager as the protected site, and configure a recovery site for the protected site. When the protected site stops providing services, the recovery site can take over to guarantee uninterrupted services. For detailed configuration, see site disaster recovery configuration in Quick start-UIS enhanced services.

• Storage replication—Storage replication disaster recovery relies on array-based replication to provide service backup and recovery across different sites. The protected site and recovery site can perform automatic service recovery if both of them support storage replication adapters (SRAs). If the storage arrays of the sites do not support SRAs, you must manually prepare the storage environment before switching over the services between sites. As a best practice, use storage arrays that support SRAs.

• Disk backup—You use a VM or production node (physical device) installed with disaster recovery software as a protected object and use a local UIS Manager site as the recovery site. With the real-time replication function provided by the client software, you can protect the data on the source VM or production node. With the snapshot chain and real-time synchronization mechanisms, data can be backed up and synchronized in seconds to satisfy the requirements of high-performance RPO data recovery.
