Sync and split technology is an example of an innovative (and challenging) solution for storage recovery that complements or duplicates many of the features RMAN can accomplish independently. Over the past five years, sync and split has become a widely used technology to provide immediate and very fast system recovery at the storage hardware level.
In this chapter, we will provide an overview of what sync and split technology refers to. We won’t be discussing any single implementation in particular, but rather discussing the implications for RMAN and database backups. After the overview, we go into the specific steps required to integrate sync and split solutions into an RMAN backup strategy.
