Device Configuration

With Device Configuration, you can create file system devices, data mover file system devices, and deduplication devices using a wizard application, or you can modify the configuration of existing devices within the Windows environment. Devices are configured to a folder on a specific shared drive. When you specify the device as your backup destination, each session is stored as an individual file within that folder.

Arcserve Backup lets you configure disk-based devices without stopping the Tape Engine. When you configure devices, you can change the credentials of devices used for remote access by clicking Security from the Disk-Based Device Configuration dialog.

From Device Configuration, you can add one or many devices. When you click Next, Arcserve Backup verifies the validity of information specified for all devices and displays the results as tool tips. Point your mouse to the icon in the Device Name column. Device status is indicated by the series of icons described in the following table:

Icon	Description	Function
	Pending	Displayed while a device is being created or edited.
	Verifying	Displayed while a device is being verified.
	Passed	Displayed when a device passes verification.
	Failed	Displayed when a device fails verification.
	Warning	Displayed when a device passes verification, but requires corrections.
	Ready	Displayed when a device does not change and is ready for use.

When the status displayed is Failed:

Ensure the paths specified for the Location are unique for each device.
Ensure the security credentials are accurate.
Check that the volume is shared.
Check that the path specified for the location is valid.

Staging backup operations can quickly consume a large amount of free disk space on file system devices. Due to the maximum file size limitations of FAT 16 and FAT 32 file systems, you should not use these file systems on file system devices designated for staging operations.

You can specify the Location of the FSD using any of the following formats:

To specify a path to a local folder, use the format that follows:
```
c:\fs_drive
```
To specify a path to a folder that resides on a mapped drive, use the format that follows:
```
k:\fs_drive
```
Arcserve Backup converts the path and prompts you for credentials when you are finished editing.
To use a shared folder as a File System Device that you want to access through the network, specify the Universal Naming Convention (UNC) path of the shared folder, for example, \\SERVER1\fs_drive\. For UNC path, we encourage users to always put the correct credentials in the Security Window. Incorrect credentials may lead to unexpected results on some platforms, such as Windows 2008, Vista, and others.

When you use a mapped drive as an FSD:

Arcserve Backup can use the mapped drive, but you must have logged in to the mapped drive previously.
If you use a mapped drive for an FSD, Arcserve Backup converts the mapped drive to a universal naming convention (UNC) path and prompts you to provide log in credentials when you click Finish.
- The log in credentials provided must enable full access to the mapped drive.
- By default, Arcserve Backup uses the Arcserve Backup System Account to gain access to each remote FSD. You can change the credentials that you use with the selected file system device by using Security.
- You do not need to provide credentials when you create an FSD using a local disk.

Important! Arcserve Backup does not support sharing an FSD with multiple Arcserve Backup servers. When an FSD is shared, the Arcserve servers using the FSD can overwrite the other server's backup data.

Note: Arcserve Backup supports configuring an aggregate total of 255 FSDs and DDDs (only if the number of physical devices configured is 0).
