Can My RDS for PostgreSQL Instance Still Be Used in the Backup Window?

A backup window is a user-specified time during which RDS for PostgreSQL instances are backed up. With these periodic data backups, RDS for PostgreSQL allows you to restore DB instances to a point in time within the backup retention period.

• During the backup window, you can still use your instance except rebooting it on the console.
• When starting a full backup task, RDS first tests connectivity to your instance. If either of the following conditions is met, the test fails and a retry is performed. If the retry fails, the backup task fails.
  • DDL operations are being performed on the DB instance.
  • The backup lock fails to be obtained from the DB instance.
