According to Gartner, two-fifths of companies that experienced a major disaster that caused a system outage never resumed operations, and one-third of the remaining companies went bankrupt within two years. Business continuity matters, especially in the digital age, people have more ways to access businesses than ever before and the requirement of service continuity is more stringent than ever. However, things unexpected happen all the time, physical machine will fail eventually, business owners urgently need a comprehensive disaster recovery solution that can protect their business across on-premise and off-premise environments.

Sangfor disaster recovery management (DRM) solution includes active-passive disaster recovery and active-active stretched cluster solution for homogeneous environment and heterogeneous environments.

Background - Sangfor Disaster Recovery Management (DRM)

Disasterrecovery Min. 1s Mins Based on RPO and IO speed No limitation
Stretched cluster 0 30s 1 Gbps fiber / 10 Gbps fiber, RTT<=5ms <=50km

For disaster recovery solution between 3rd party platforms and Sangfor cloud (HCI or MCS),

Critical Business – CDP Hot Standby DR  Important Business – VM Synchronization DR  Secondary Business – Quick Recovery DR 
  • Use CDP to realize real-time synchronization
  • DR Site in hot-standby mode
  • One-click switch to enable backup server
  • Realize RPO=0, switch in 1 minute
  • Use CDP to transmit data from production site to DR site with real-time or scheduled mode
  • DR site in shutdown mode, during DR, it will pullup DR VM and ta over the business
  • Realize RPO=O, switch in 5 minutes
  • Real-time/scheduled backup to HCI resource pool to support rapid reconstruction and recovery of TB-level data 
  • Recover data to HCI when disaster happens
  • Realize RPO=0, switch in 30 minutes
