Business Continuity & Disaster Recovery
Any event which causes unacceptable interruption of business operations for an unacceptable time-period.
Must have direct effect or impact to organization and/or Functional units
- Critical Application
- Comparative Position
- Binding Facilities
Business Continuity Planning (BCP) or Operational Readiness is a statement of :
- actions to be taken
- the resources to be used
- the procedures to be followed
- includes all Standard Operating Procedures(SOPs) in the event of a disaster
Before ,During & After a disaster which ensures the continuity of all the critical and essential Operation.
A Disaster Recovery Plan (DRP) is a sub set of BCP specific to Infrastructure or Information Systems.
Reduce >>> Respond >>> Recover >>> Resume >>> Restore >>> Return
Alethe Consulting Approach to DR and Key Considerations
- Different Seismic zone
- Different Geographical zone
- Different Political zone
- High Availability of all Critical and Essential applications existing in different Vulnerable Points and Vulnerable Areas
Key Considerations for Disaster Recovery – Replication
Synchronous data replication
All data written to Database/Disk/cache of local and remote targets before I/O is complete and acknowledged to local host
Synchronous data replication
All data written to Database/Disk/cache of local and remote targets before I/O is complete and acknowledged to local host.
At any time, data on target will be in the exact same state as on the primary host. In environments with bandwidth constraints, this can have performance implications on production storage. Requires Dark or Managed-Lit Fiber
Asynchronous data replication
Write acknowledged after write to local Disk/Cache/Database and then changes are replicated to remote array asynchronously by placing each write into a queue, so that production performance is not affected by Wide Area Network (WAN) latency.
Semi-synchronous data replication
Allows the system to operate in synchronous mode until certain performance thresholds are reached, and then automatically switches to asynchronous mode.
Alethe Consulting has in depth understanding & vast experience in setting up Disaster Recovery Solutions. We have implemented multiple DR solution for various customers across different geographies
The selection criteria of replication methodology based on the following requirement:
- Recovery Point Objective
- Recovery Time Objective
RTO (recovery time objective) is the time that elapses between the loss of access to data and the recovery of data access. The shorter the RTO, the better. RPO (recovery point objective) is the point in time when the data backup took place.
Alethe has expertise based on the business requirement & analysis of RPO & RTO, following storage solution will help in achieving based on the organization requirement:
- One way Disaster Recovery site
- Two way DR Recovery Process
- Three way Disaster Recovery Process
