Under a new database backup plan:

  • Full backups of the database are taken every 6 hours starting at 00:00.
  • Differential backups are taken every 1 hour starting at 01:00, except for intervals of 6 hours (when full backups are taken).
  • Transaction/redo log backups are taken every 30 minutes starting at 00:00. The transactional/redo log is reset/cleared after a backup is taken.

Due to a missed scenario during the testing phase, a development error in setting wrong query conditions resulted in the loss of all records from a table at 13:45, which had data prior to the implementation of the backup plan. All further backups were taken as per the mentioned schedule.
