6. Select the Display A Reminder Every check box if you want to provide reminder balloons in the notification area of the desktop (lower right corner) when the computer goes offline. Specify how often (in minutes) you want the reminders to appear in the Minutes box. 7. Select the Create An Offline Files Shortcut On The Desktop check box if you want to place a shortcut to the Offline Files folder on the desktop. 8. Select the Encrypt Offline Files To Secure Data check box if you want to encrypt offline files to keep them safe from intruders who might gain unauthorized phys ical access to the client computer.

The elements of good backup operations are easy: back up the data to sound media, store it in a safe place, do these two things frequently, and audit the practice. But the elements of securing the backup process are much broader, and more choices must be made. Follow these guidelines when designing security for backup and recovery operations:

Note The Encrypt Offline Files To Secure Data check box is disabled if you are not an administrator on the computer, the local drive is not NTFS or does not support encryption, or your system administrator has implemented an encryption policy for Offline Files.

Ensure that personnel who perform backup are trained and understand their job. Audit their activity to ensure the job is being done correctly and securely. Ensure secure storage, both off-site and on-site, for storage media. Ensure that only authorized individuals can bring backup media on-site. This prevents a malicious or unqualified individual from using the media to restore old data over new, or from using backups to build new servers and then provide themselves access to sensitive data. Ensure that media is transported in a secure fashion. Media should be perma nently labeled. Media should be transported in locked containers. Develop backup and restore strategies and test them. Separate the user rights of backup and restore. By default, the Backup Operators group has both privileges. By separating these rights, you make sure that the person who backs up the data does not have privileges to restore the data. In this manner, you prevent a disgruntled employee from restoring old data over new. Back up data on system and boot volumes and system state. Create an Automated System Recovery (ASR) data set backup when the operating system changes. Operating system changes include the addition of hardware and drivers and the installation of a service pack. If you have an ASR backup set, recovery will be easier. ASR protects only the system a backup of data at the same time is required.

This is exactly the kind of plumbing we earlier deemed evil when discussing the benefits of using a Container and Application Server. Application code, armed with the right tools, should be free of this kind of error-prone and excessive noise. Also, it is very expensive to make a remote method call to an entity bean from a client. If the client had to call getFirstName(), getLastName(), etc., to get information about a customer it was displaying, performance would suffer. This is where the Value Object Pattern came in. EJB 3.x eliminates the need for this pattern because persistent objects become value objects automatically when they are detached from a persistent context. One side effect we encounter in dealing with detached entities revolves around entity relationships, which we ll discuss later.

Notify Me And Begin Working Offline. Select this option to specify that the user can work offline if the network connection is lost, because network files will continue to be available.
