    Related to Unused compression in RMAN backup for 10.2.0.4 database

      Hi

      I recently read through one of the document related to Unused compression in RMAN backup for 10.2.0.4 database. According to this

      Unused Block Compression is done, if all of the following conditions apply:

      + The COMPATIBLE initialization parameter is set to 10.2

      + There are currently no guaranteed restore points defined for the database

      + The datafile is locally managed

      + The datafile is being backed up to a backup set as part of a full backup or a level 0 incremental backup

      + The backup set is being created on disk.

      I have two queries

      1) What is meant by "uaranteed restore points defined for the database"
      2) If backup is being directly taken to tape, this feature would not be used
