Database protection

REV. B 02/03 PN 51680-1
Creating alternate copies of your patient database is important, but can be a lengthy procedure.
Therefore, Carl Zeiss Meditec recommends that you choose a schedule that suits your office,
preferably one that does not interfere with patient care and testing. Whether you perform 25
visual field tests each week or five, every test worth saving (whether to floppy disk, hard disk,
or both) is worthy of being protected by being maintained on alternate storage media. In the
event of database failure, alternate copies of your database can be used as a backup measure
to minimize or eliminate data loss.
The storage media used with the HFA II (floppy disks and/or magneto-optical discs) are not
indestructible. Improper care and handling will affect the contents and render the media
unusable. Floppy disks and magneto-optical discs also have a limited shelf life and should not
be used indefinitely. It is advisable to rotate between at least two sets of storage media. Always
use formatted disks for these procedures. Information on the proper care and handling of
storage media is covered at the end of this section, as well as in Section 12.
Your HFA II comes equipped with a floppy disk drive and may have a magneto-optical disc
drive. This affords owners optional methods for backing up hard disk data. The magneto-
optical disc is the most efficient and effective method of database protection for the HFA II.
The recommended database protection procedure for your HFA II involves the following three
steps:
1. Keep a floppy disk in the drive at all times to capture saved data. On a weekly basis, make
a copy of the disk using the DUPLICATE FLOPPY file function.
2. On a weekly basis perform a magneto-optical disc backup, if available, of the entire
database using the BACKUP utility. Include the backup date on the disc label and rotate
between two or more discs for added protection.
3. Store backup magneto-optical and floppy disks in a safe location away from the HFA II.
