Volumes
The removable media on which NetBackup stores backups are called volumes.
These media (for example, 8 mm cartridge tapes) have been assigned media
IDs and other attributes so their content, location, and so on can be tracked.
The attribute assignment occurs when the media is added to Media Manager
and can be done automatically or by the administrator. See the Media Manager
System Administrator’s Guide - Windows NT Server for information on adding
volumes.
NetBackup master servers keep a media catalog with records about the
volumes where backups are stored. Media Manager controls the mounting of
volumes on the devices and keeps a volume database with records that
indicate where the volumes are located.
Note:
When the storage unit is on magnetic disk, NetBackup sends the backup
to the file path specified during setup of the storage unit and records the
location in the NetBackup media database. The operating system manages the
actual writing of data.
Backup Policies (Classes)
A NetBackup class defines the backup policies for a specific group of one or
more clients that have similar backup needs. NetBackup can have a single class
that includes all clients or many classes, some of which can include only one
client. A NetBackup client must be in at least one class and can be in more than
one.
The administrator defines the properties of a class. The properties that can be
assigned depends on the type of clients that the class supports and includes:
• General attributes that define things such as:
• Storage unit to use for backups of clients in this class.
• Volume pool to use for backups of clients in this class. A volume pool is
a set of volumes that the administrator can assign for use by specific
classes or schedules. For example, it is possible to have one volume pool
for weekly backups and another for quarterly backups.
• List of clients that belong to the class.
