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. )

data has been transferred, thus ending the backup proc- ess.

Cancelling Backup operation

Press the ARCHIVE button during Backup Recording to halt operation. The Archive Pointer will be re-positioned to where operation was stopped, and the next Backup Re- cording will begin at this point. The unit will halt operation while the ARCHIVE button is blinking; please wait until the button’s light stays on.

Individual settings during Backup operation

Choosing a backup system

Select either “ON” or “OFF” for the ARCHIVE OVERWRITE setting on the <INITIAL SET UP> menu.The default set- ting is “OFF”. Use the JOG dial and SHUTTLE ring to check that settings are as desired. (Refer to page 30.)

a)“OFF”: Data will be added to the storage medium from the point where previous Backup Recording was completed.

Auto-eject at the completion of backup

The unit can be set so that the storage medium will be automatically ejected upon completion of Backup process. Refer to page 31 for details on the setting procedure.

Besides this setting, the archive medium will be automati- cally ejected under the following conditions.

• When the archive medium becomes full during One-touch

Backup.

• When the archive medium becomes full during Timer

Backup.

• When the ARCHIVE button is pressed once again, after

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

operation has been initiated with the ARCHIVE button.

• When a recording malfunction, medium error, or system

error occurs during Backup operation.
