is like a computer in many respects. Its hard drive can “crash” and
its floppy disk can “get corrupted”. Because visual field test results represent an important part of
your patient’s ophthalmic history, it is imperative that you take steps to safeguard the integrity of
the data by creating backup copies of all test results. In addition to patient data, you
can protect Custom test patterns, Main Menu button definitions, network settings (if
you have licensed HFA-NET Pro), and System Setup selections against loss in the
event of a hard disk failure. Maintaining up-to-date backup copies of your patient
database is insurance against loss.
After reading this section you will be familiar with:
• recommended backup techniques
• how to back up and restore menu configurations
• how to deal with database failures
• how to keep a similar database on multiple HFA II-
i
’s
• proper handling of USB storage devices, USB floppy disk drives, and

floppy disks
CAUTION: Never turn off the HFA II- i or remove a USB storage device or USB floppy
disk drive while the hard drive or USB device is reading or writing data. Wait for the
HFA progress bar to complete and/or the USB device’s activity light to cease. This may
cause permanent loss of valuable data.
CAUTION: Make sure your USB devices are secured against malware/viruses. Patient
data on USB devices can become corrupted when inserting into computers for
backup or transfer. The use of anti-virus software on computers is recommended and
is the responsibility of the user.
CAUTION: To protect your HFA data from unauthorized access, use dedicated USB
devices for storage of HFA data. Do not use these USB devices for any other data or
application. HFA data is not encrypted.
CAUTION: Health care providers have responsibility for the protection of patient
health information (PHI), both hardcopy and electronic. To protect patient
confidentiality of your electronic HFA data, the use of encryption is recommended
and is the responsibility of the user.
