Let's assume you recently installed the management server and you have not done any backups.
You have schedule the backups to take place every three days. You performed a backup, and it is
stored in the backup1 folder. The next scheduled backup occurs on day 4 and it is saved in the
backup2 folder. If your database fails, you can restore the database from day 1 or day 4. Let's
assume you have a scheduled backup on day 7, which is saved to the backup1 folder. This backup
replaces the backup from day 1. The available backups are from day 4 and 7. Assume you click the
Backup Now button on day 8, the backup is saved in the CURRENT folder because the backup is
recording the current state of the database. If your database fails, you can restore the database
from day 4, 7 or 8, as described in the following table:
