Using Logical Data Protection and Recovery to Improve Data Availability
[chapter]
2005
Lecture Notes in Computer Science
Data availability is crucial to overall application availability. This paper describes data failures and classifies them as either physical or logical. Physical data failures such as data loss and corruptions are introduced in the I/O layers; logical data failures are introduced in the application layer. Current data protection techniques are geared towards physical data failures. This paper reviews physical data protection techniques and their limitations. It then introduces the concept of
