Restore And Rollback in RecoveryManager Plus

The restore option allows you to re-instate an object’s attribute value from the selected backup. Any changes made to attributes other than the ones in the selected backup will remain the same once the restoration is complete.

The rollback option allows you to undo all changes made to an object’s attributes after the selected backup point, and the object will be rolled back to the state it was at the time the backup was taken.

To explain the difference between the two features, let’s take a look at an example.

• A user has been created with the address and phone number attributes. The user object is backed up and this is the first backup version of the user object.
• A week later, the email address attribute is added to the user object. The user object is backed up and this is the second backup version.
• Another week later, the phone number attribute is modified. The user object is backed up and this is the third backup version

Now, restoring the user object to the first backup version will provide the following results:

• The address and phone number of the user object will be changed to reflect the value in the first backup version.
• The email address attribute will remain the same.

On the other hand, rolling back the user object to the first backup version will provide the following results:

• The address and phone number of the user object will be changed to reflect the value in the first backup version.
• All changes made to the attribute values after the first backup will be discarded. The email address attribute was added after the first backup point and hence the attribute value will be deleted.
