Maximum Fragment Size
Specifies (in megabytes) the largest fragment size that NetBackup can create
when storing backups. To specify a fragment size, type a value of 50 or larger.
To specify no fragmentation, type 0.
For more information, see “Fragmented Backups” on page 446.
Note:
If you change the fragment size, you can still restore backups that were
written with the previous fragment size.
Maximum Multiplexing Per Drive
Specifies the maximum number of backups that NetBackup will be able to
multiplex onto any single drive in the storage unit.
• Specify any value from 1 through 32. The default is 1, which disables
multiplexing and allows only one backup job at a time on a drive.
• For values greater than 1, NetBackup sends concurrent, multiple backups
from one or several clients to a single drive and multiplexes the backups
onto the media. See “Multiplexing” on page 135 for more information.
Adding Disk Type Storage Units
This section explains how to configure a NetBackup storage unit that resides in
a directory in a disk partition.
Before using a disk storage unit, configure the disk as explained in your
operating system documentation. To calculate the approximate disk space that
NetBackup requires as it creates backups, multiply these numbers:
(largest backup size X (number of concurrent b 1))
+
Space for the backups that result from restores that are concurrent with
backups
For number of concurrent backups, use the Maximum Concurrent Jobs setting as
defined below.
