Use this dialog box to view or modify the mount path properties of a disk library.
Properties
-
Mount Path
The path where the data is written to and read from.
-
Free Space (MB)
The remaining free space on the mount path.
Note
Before you perform a data protection operation, always verify and ensure that sufficient disk space is available on the mount paths that are used by the operation. Data protection operations might be affected if the amount of space on the mount paths is insufficient.
The free space information is, by default, refreshed every 30 minutes. The refresh time can be changed in the Interval (Minutes) between disk space updates option in the Service Configuration tab of the Media Management Configuration dialog box in the Control Panel.
-
Size on Disk
The total amount of backup data that is stored in the mount path.
-
Capacity (MB)
The total amount of space on the mount path.
-
Application Size To Be Pruned
The size of the data on the disk that is eligible for pruning during the data aging process.
-
Supports drilling of holes
Indicates whether the mount path supports micro pruning. (Micro pruning is the process of pruning individual data blocks without sealing the corresponding DDB (deduplication database).
Note
Some file systems do not support space reclamation of deleted data blocks (drilling holes) that are not at the end of the file. The lack of support for micro-pruning is usually related to the lack of support for sparse files.
-
Description
Use this field to enter a description about the mount path. This description can include information about the mount path's content, any cautionary notes, and so on.
Use unbuffered I/O
Specifies that the MediaAgent will bypass the Microsoft Windows file system buffering by enabling unbuffered I/O. Select this option to increase the speed of operations that access the mount path. This option is only applicable for Windows MediaAgents and disks that are mounted directly (UNC paths are not supported).
Reserve Space for Silo Restore
Select this option if you want to use the mount path to receive Silo stores from Silo restore operations only. When this option is selected, this mount path is not used to store backup data.
Status
-
Status
The status of the mount path.
-
Enable MountPath
When selected, the mount path is available for all operations from all the MediaAgents accessing or sharing this mount path. Clear this option to disable operations for all the MediaAgents accessing or sharing this mount path.
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 a hardware failure.
To disable the mount path for only the write operations and make the data available for read and prune operations, use the Disable mount path for new data in the Allocation Policy tab.
-
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 will be available from all the mount paths that are configured in the device. Clear this option to disable all operations on the device.
Caution
A device can have multiple mount paths configured on the device. Disabling the device will disable all the mount paths and their corresponding MediaAgents from accessing the device.
A device's online/offline status reflects its logical availability to the MediaAgents accessing the device, not its physical availability. For example, a device can be enabled even if it is physically unavailable due to a hardware failure.
