Mount Path Properties (Allocation Policy)

Use this dialog box to view or modify the usage properties specified for the mount path. Note that all the options described in this help may not be available and only the options displayed in the dialog box are applicable.

Mount Path Allocation Policy

• Maximum Allowed Writers

  Specifies that there is no maximum limit on the number of concurrent data protection operations to the mount path.

• Allocate No. of Writers

  Specifies the maximum number of concurrent data protection operations on the mount path. If necessary, use the space to modify the maximum number of concurrent data protection operations on the mount path.

• Disable mount path for write

  Specifies that the mount path will not be available for writing data. However read operations can be performed on the data available in the mount path.  (If you wish to take the mount path offline, clear the Enable MountPath option in the General tab.)

Space Allocation

• Reserve Space (MB)

  Specifies the total amount of free space that must be available at all times, when the system writes data to the mount path.  If necessary, use the space to modify the amount of free space. Note that this option is not applicable for a cloud target.

• Use until free space on mount path reaches Reserved Space

  Specifies that the entire mount path (less the reserve space) will be used to store valid data. Note that this option is not applicable for a cloud target.

• No Restriction

  Specifies that there is not restriction on space allocation. This option is only applicable for a cloud target.

• Do not consume more than n GB

  Specifies that only the specified amount of space will be used to store valid data.

Fragmentation

• Minimize fragmentation by allocating write blocks of n MB

  This option allows the MediaAgent to pre-allocate a specified portion of the backup chunk before beginning a write operation. The chunk size should be determined based on the disk array and the file allocation unit size. The default size is 128 MB. Note that this option is not applicable for a cloud target.

  Pre-allocating a specified chunk size before the write operation enables the Operating System to allocate contiguous disk clusters based on the requested chunk size, thus reducing disk fragmentation. This option is supported on Windows MediaAgent.
