Configuring and Using Backup Devices

Configuring File Devices

 

You specify the capacity of a file device when you first format the

 

medium. When you reformat the medium, you can specify a new size;

 

however, the originally specified size will be used. You can change the

 

capacity of a file device only by deleting the file from the system.

 

The path to a file device can be anywhere, whether it is an internal drive

 

or an external portable hard drive.

Handling Mount

Media are handled differently from physical devices. When a standalone

Requests

file device (medium) becomes full, Data Protector tries to write to the

 

same file again. Data Protector does not recognize that any other file

 

exists, so it issues a mount request.

 

When the mount request occurs, the existing file has to be moved or

 

renamed (for example, by exchanging the ZIP media). The original file

 

should no longer exist after the move. You then need to confirm the

 

mount request. Data Protector will recreate the original file with the

 

default file capacity. After the backup is finished, the file created by Data

 

Protector contains the last part of the backup.

 

For Jukebox file devices, Data Protector issues a mount request when all

 

media (files) are full.

Prerequisite

Before you configure a file device on a Windows system, disable the file

 

compression option. This can be done using Windows Explorer.

 

Right-click the file, select Properties and deselect Compress under

 

Attributes. If Compress is selected, Data Protector will not be able to

 

write to the file device.

 

 

IMPORTANT

Do not use the name of an existing file for configuring a file device,

 

because the existing file will be overwritten.

 

Do not use the same filename for configuring several file devices, because

 

every time a file device accesses the file, it will be overwritten.

 

 

How to Configure

To create a standalone file device, specify the Standalone device type in

File Devices

the Add Device wizard. Refer to Figure 2-2. As a device address, specify

 

a pathname for the file device, for example, C:\My_Backup. Refer to

 

Figure 2-3. For detailed steps, refer to the online Help index keyword

 

“configuring file devices”.
