Thank you very much Clifford,
For tracking changes, not necessarily in blocks level, can be done with Storage Foundation or do I have continuous snapshots with SF for Oracle RAC and replicate with Veritas Replicator replicate (VR) ?
I need a protect mechanism most compatible SNIA definition for CDP:
(http://www.snia.org/sites/default/files/CDP_Solving_recovery_20080808.pdf)
"The CDP SNIA Definition
Continuous Data Protection ( CDP ) is a methodology que continuously captures or tracks data modifications and stores changes independent of the primary data , enabling recovery points from any point in the past . CDP systems may be block- , file- , or application- based and can Provide fine granularities of restorable objects to infinitely variable recovery points . So , According to this definition , all CDP solutions Incorporate these three key attributes:
1. Date changes are continuously captured or tracked
2 . All data changes are stored in a separate location from the primary storage
3 . Recovery point objectives are arbitrary and need not be defined in advance of the current recovery
A number of technological approaches Recognized deliver CDP , including block- , file- , and application -based.
Today , many vendors offer varying degrees of support and awareness of specific application and data environments . But regardless of the underlying technological approach Utilized , CDP can offer faster data retrieval , enhanced data protection , business continuity and Increased with lower overall cost and complexity .
