You are managing an Oracle Database 11g database with the following backup strategy: 1. On Sunday, an incremental level 0 tape backup is performed 2. Monday through Saturday, a cumulative…

A level 0 incremental backup copies every data block that has ever been used in the database, serving as the base image from which all subsequent incremental backups are derived. It does not filter by change time.

A cumulative level 1 backup, unlike a differential level 1, always backs up every block that has changed since the most recent level 0 backup regardless of whether a more recent level 1 exists. This means each Monday-Saturday backup captures all changes since Sunday's level 0, growing in size throughout the week.

A level 0 backup does not reference any prior level 1 - it unconditionally captures all used blocks and serves as the base image, not a changed-block backup relative to level 1.

Backing up all blocks changed since the most recent incremental backup at any level describes differential level 1 behavior, not cumulative level 1 behavior; cumulative always measures from the level 0.
