Making backups (continued)
Restrictions during Backup Recording
1. Selectable recording intervals for simultaneous backup
Recording interval for simultaneous backup of recorded
data is determined by the data-writing speed of the con-
nected device. For reference, the following chart provides
a list of interval modes which can be selected when the
unit is used in conjunction with a Hewlett-Packard C1556A
drive (DDS3). (The same modes apply when the main hard
disk drive has been expanded.)

2. Precautions when designating Timer simultaneous
backup
The Backup Program, which can be designated as an indi-
vidual operation, can also be designated with the RECORD
and POWER Programs. The following items apply when
designating these multiple program modes.
1) There may be restrictions imposed by the other record-
ing devices, it is recommended that adequate program
checks are run before actual operation.
*) Precautions when connecting devices requiring time to
halt startup (e.g., archive devices, tape recording devices
etc.)
• Using the Backup setting's designated time plus 5 min-
utes (the halt startup time of the peripheral recording de-
vices) as a gauge, set the unit so that modes do not change.
(Refer to illustration 1.)
• Even when only designating the backup mode, add one
minute or more to the backup operation time, and set other
programs to start and stop. ( Refer to Illustration 2. )

ARCHIVE button operation
The transfer of data, for backup purposes, from the unit's
HDD to a peripheral recording device is performed in fixed
data amounts each time. Data transfer begins when 30MB
is recorded onto the HDD. Accordingly, even if the ARCHIVE
button is lit, there are times when the operation of archive
devices are stopped in order to reduce wear on these de-
vices. To end the backup, please press the ARCHIVE but-
ton one more time as the button remains lit even after the
backup process is finished. The ARCHIVE button will start
blinking when pressed, and will stop blinking when recorded

Cancelling Backup operation
Press the ARCHIVE button during Backup Recording to
halt operation. The Archive Pointer will be re-positioned to

button's light stays on.
