Full or Partial Recovery
Ingres allows you to perform full recovery, which involves recovering an entire database, or partial recovery, which recovers selected tables in a database.
Partial recovery entails recovering data from a backup copy at a level of granularity finer than the entire database. In the event of failure, Ingres can, if possible, mark less than the whole database physically inconsistent. The advantage of partial recovery is that it reduces recovery times by requiring only recovery of logically or physically invalid data.
