supports the following levels of recovery to maximize the availability (uptime) of the system and minimize data loss even if a system crash or site disaster occurs:

Data Backup & Restore:

Periodical backup of data to secondary storage automatically to minimize data loss if a system crash occurs.

Hot failover:

supports different modes of hot failover such as Active-Standby mode and Active-Active modes to minimize system downtime or unavailability.

• In Active-Standby mode, the active server will be online and synchronize data to the standby server. At the same time, the standby server will monitor the status of the active server and activate itself when the active server crashes.
• In Active-Active mode, both servers are online and provide the same services, it improves performance of the whole system and provides load balancing function.

Disaster Recovery:

supports replication of data to an off-site location to overcome the need to restore the data (only the systems then need to be restored or synchronized).
