What is DR Prophet®?
Moving beyond traditional failure-prone, once-a-day tape backup strategies, DR Prophet® combines local and remote disk-level protection into an integrated and cost-effective solution. DR Prophet® allows enterprises to recover quickly from failures based on point-in-time snapshots and rapidly resume normal business operations either locally or from a remote DR site.
This architecture also includes a complete set of standby servers that mimic the exact configurations at the production site. In case of a catastrophic failure of the production site, business operation can be quickly resumed at the DR site using these standby servers and the data on the Remote Replica.
DR Prophet® Client Agents
For applications servers running as VMware VM’s, however, no client agents are required as DR Prophet® vSphere Module connects directly to vSphere via native VMware API’s to orchestrate snapshot operations including entering the applications and the guest OS into the quiescent mode.
Automatic Protection Configuration
DR Prophet® can intelligently perform complicated configuration processes to protect the data on AIX, Windows, and VMware vSphere application servers with minimal human intervention. The protections are set up based on pre-defined policies and system performance requirements. It prevents human errors and guarantees that the important data is properly protected.
Agile and Elastic Scheduling
Integrates with DiskProphet™ to automatically predict the probability of failures in advance and initiates pre-emptive actions by rescheduling snapshots.
After the full first sync, all subsequent snapshots consist only of delta block changes. This improves space efficiency by reducing the footprint for the snapshots. Every recovery point is references to data blocks of the full data at a certain point in time. Any in between snapshot can be deleted with no impact to recoverability of the data.
VMWare Protection and Recovery (DR Prophet® vSphere Module)
1. No client agents is needed 2. Support LAN 3. Support VMware native API’s 4. Bootable backup VM on vSphere after restore
WAN-Optimized Remote Replication
In addition to local mirror backups, remote replications can be scheduled to transmit local data to a remote DR site. The WAN-optimized thin replication sends only changed data to save time and bandwidth consumption. In additionl, replication compression and encryption are also fully supported.
Mirrored Disks for Fault Tolerance and Local Protection
As a first-line defense against system failures, DR Prophet® preserves the protected data on a local backup storage server. All data protection related disk operations are performed against the mirrored disks on the storage server without incurring any workload on the production system.
Windows Agent IO Throttling
Users can manually enter the bandwidth limit (throttling) on the DR Prophet® management server o prevent aggressive backup or restore activities that might adversely impact the normal production I/O traffic.
Application-Aware Data Protection
To guarantee data integrity and snapshot consistency, DR Prophet® runs a lightweight agent on the application server to collect system status and application states. It keeps track of any system configuration changes and communicates with active applications such as Microsoft SQL Server, Oracle Messaging Server, or Microsoft Exchange Server to ensure transactional data integrity, even across multiple storage volumes.
Snapshot for Data Protection and Instant Recovery
DR Prophet® can create as many as 1,024 periodic, scheduled or on-demand, delta snapshots per LUN to keep the point-in-time states of a volume. It features Direct-on-Write (DOT) technology to avoid write IO impact on the production system. Unlike Copy-on-Write (COT), DOT does not require any pre-allocated disk space to keep the snapshot data. The Snapshot Viewer feature allows administrators to create multiple instantaneous virtual copies of an active dataset that the primary application server can assign to additional servers with read/write access for concurrent and independent processing without affecting the activity on the original dataset.
Site Failback for Windows Disaster Recovery
When a physical Windows server becomes unavailable due to site failure, a snapshot of the remote replica is promoted as a storage target to be mounted on the spare application server at the DR site. As the production site recovers, the operator can select any snapshot at the DR site and restore the production server by failback reincarnation.
Non-Disruptive DR Rehearsal
DR rehearsal can be conducted any time on the mirror LUN at the storage server without introducing additional IO activity to the production server. The system can be recovered from any known-good snapshot by an automated validation and mounting process.
Centralized Management and Reports
DR Prophet® web console is a user-friendly graphical user interface provided by the management server to manage multiple application servers and storage servers. Through this management “dashboard”, system administrators can get a clear view of the protection relationship and gain vital system information such as performance statistics, replication status, backup scheduling, and system events. Also, detailed reports can be generated for system analysis, troubleshooting, performance tuning, filing, or maintenance.
