Disaster Recovery - Zero Recovery Objective - COst Benefit
Posted on 2011-09-18
We recently did a BIA excercise in our organization and as an out come some of the application were said to have an "Zero" RTO-RPO by business.
From IT and overall business perspective we know that applications can have an RTO/RPO for at least 1 day.
We need to go back to business with a simple analysis with the following points
1) Kind of solution required for "0" RPO solution , ( Assuming DB"s are oracle , mysql , MS sql and data is on SAN) ( Distance of alternate site min 200 Km)
2) Challenges with these solutions ( Cost , distance limitation , performance lag , type of expensive data connectivity refund etc)
3) Disadvantage in terms of cost / performance as compared to solution to be used for Rto /RPO 1 to 2 days
4) A very high level overall solution cost for zero RPO solutions.
Any high level analysis data specially in terms of cost or pointers to links having such data will be really helpful.
