Mount Path Properties (General)

Use this dialog box to view or modify the mount path properties of a disk library.

Properties

• Mount Path

  The path to which the data is written to and read from.

• Free Space (MB)

  The remaining free space on the mount path.

  	Before performing a data protection operation, always verify and ensure that sufficient disk space is available on the mount path(s) used by the operation. Data protection operations may get impacted if the amount of space is insufficient on the mount path(s).
  	The free space information is by default refreshed every 30 minutes and can be configured using the Interval (Minutes) between disk space updates option in the Service Configuration tab of the Media Management Configuration dialog box in the Control Panel.

• Valid Data (MB)

  The total amount of backup data stored in the mount path.

• Capacity (MB)

  The total amount of space in the mount path.

• Description

  Use this field to enter a description about the entity. This description can include information about the entity's content, cautionary notes, etc.

Use unbuffered I/O

Specifies that the MediaAgent will bypass the Microsoft Windows file system buffering by enabling unbuffered I/O. Enable this to increase the speed of operations accessing the mount path. Note that this option is only applicable for Windows MediaAgents and disks that are directly mounted (UNC paths are not supported ).

Reserve Space for Silo Restore

Select this option if you would like to use the mount path to receive silo stores from silo restore operations only. When selected, this mount path is not used to store backup data.

Status

• Status

  The status of the mount path.

• Enable MountPath

  Select the Enable MountPath option to bring the mount path online and make it available for use. Clear this option to take the mount path offline. (To disable the mount path for write operations and make the data available for read operations, use the Disable mount path for write in the Allocation Policy tab.

  A mount path's online/offline status reflects its logical availability to the MediaAgent, not its physical availability. For example, a mount path can be enabled even if it is physically unavailable due to hardware failure.

• Offline Reason

  Indicates the offline reason, when the Status of the mount path is displayed as Offline.

Device

The following information is displayed for shared static mount paths.

• Device Alias Name

  The alias provided by the user, for the device. The alias can be changed at any time without affecting the ability to restore data that may have already been backed up using the library. 

• Device Enabled

  When selected, the device is  enabled and available for use.

  When cleared the device is disabled and hence inaccessible to the MediaAgent.

  A device's online/offline status reflects its logical availability to the MediaAgent, not its physical availability. For example, a device can be enabled even if it is physically unavailable due to hardware failure.
