A backup object is defined by:
•
Client name: hostname of the Data
Protector client where the backup
object resides.
Protector client where the backup
object resides.
•
Mount point: the access point in a
directory structure (drive on
Windows and mount point on
UNIX) on the client where the
backup object is located.

A process that creates a copy of data on
storage media. The activities are
specified in a backup specification or an
interactive session. All clients
configured in one backup specification
are backed up together in one backup
session using the same backup type (full
or incremental). The result of a backup
session is a set of media, which was
written to, also called the backup or
media set.
