If you have a server, it needs to have between 35 to 150 MB of available hard disk space. Each individual workstation needs to have at least 35 MB of available hard disk space. One of the daily routines of GradPro includes a backup routine. One of the workstations initiates this routine. The amount of available hard disk space needed for that workstation will depend on how many consecutive backups you choose to store on that workstation.
Most people elect two or three consecutive days.
Even though most servers do have a tape backup device that they routinely run to back up files on the server we still advise our clients to run this daily routine. Over the years, we have observed occasions when the server has crashed or the backup tape was not really backing up the files on the network. Because the local workstation was storing a backup of the data files, the student records were recoverable. Depending on how many backups you store you would need to have 2-3 times the amount of available hard disk space that the server does. Obviously, as your database grows the amount of available hard disk space that you will need will also change both on the server and on the workstation doing the backups.
