Virtual Volumes for Database Backup and Recovery

Virtual Volumes for Database Backup and Recovery

In the first part of this series we provided a high level view of the benefits of using Virtual Volumes enabled storage for database operations. In this post, we will examine in more detail how Virtual Volumes can improve the backup and recovery capabilities for business critical databases, specifically Oracle.

The backups for Oracle can be Database consistent or Crash consistent. In this part we will look at Database consistent backup and recovery.
