Exadata Database Service on Dedicated Infrastructure: Enhanced Controls to Configure Automatic Full (L0) and Incremental (L1) Backups

Enabling Automatic Backup during the Create Database workflow or as a separate step afterward starts the first full backup ("initial L0") immediately.

Similarly, for subsequent full backups (future L0) and daily incremental backups (L1), you can specify a time window but cannot change the day of the week when these backups must begin.

Future L0 and L1 backups will begin during the 2-hour scheduling window that the user selects for the database during which the automatic backup process will begin. There are 12 scheduling windows to choose from, each starting at an even-numbered hour. For example, one window runs from 4:00-6:00 AM, and the next from 6:00-8:00 AM. Backup jobs do not necessarily complete within the scheduled window. If you do not specify a window, the default 6-hour backup window of 00:00 to 06:00 is chosen. In this case, the time zone corresponds to the region of the Exadata Cloud infrastructure instance.

Here are the current defaults for the backup destinations, Object Storage Service, and Autonomous Recovery Service:

  • Initial full L0 backup: Immediate
  • Subsequent full L0 backups: Every Sunday
  • Daily incremental L1 backups: Every Monday - Saturday

With these enhanced controls, you can:

  1. Aside from configuring the initial L0 backup to start immediately, you can also specify whether you want the initial L0 backup to start immediately or according to the L0 schedule.
  2. Choose a time window for the future full backups to start.
  3. Choose a time window for the incremental backups to start, which can be different from the time window for the L0 backups.

    The time windows will remain the same, 2-hour scheduling windows and the default 6-hour window.
