5.15.7.1 About Application Backups

Backups provide a simple way for developers to automatically recover applications that may have been unexpectedly modified or deleted.

Oracle APEX backs up modified applications as a part of daily maintenance. Backups are automatic and do not require an administrator or developer involvement. However, applications are not backed up if they meet the following criteria:

If no changes have been made to the application since the last backup, then the application is not backed up again.
Run-time only applications are not be backed up.
Applications that are installed into runtime-only instances are not backed up.

About Configuring the Number of Backups

By default, APEX only retains the 25 most recent backups. Older backups are deleted to make room for new ones.

Instance administrators can configure the number of backups per application, or disable automatic backups all together. To configure the number of backups for each application, sign in to the Administration Services application and navigate to Manage Instance, Feature Configuration, Application Development, and update the Number of backups per application attribute. Valid values are between 0 and 30. A value of zero (0) disables the backup feature.
