cumulative incremental backup
Glossary-4
cumulative incremental backup
A type of incremental backup in which Oracle Secure Backup copies only data that
has changed at a lower backup level. For example, a level 3 incremental backup copies
only that data that has changed since the most recent backup that is level 2 or lower.
daemons
Background processes that are assigned a task by Oracle Secure Backup during the
execution of backup and restore operations. Some daemons run continually and others
are started and stopped as required.
data management application (DMA)
An application that controls a backup or restore operation over the Network Data
Management Protocol (NDMP) through connections to a data service and tape
service. The DMA is the session master, whereas the NDMP services are the slaves. In
an Oracle Secure Backup administrative domain, obtar is an example of a DMA.
data service
An application that runs on a client and provides Network Data Management
Protocol (NDMP) access to database and file-system data on the primary storage
system.
data transfer element (DTE)
A secondary storage device within a tape library. In tape libraries that contain
multiple tape drives, data transfer elements are sequentially numbered starting with 1.
database backup storage selector
An Oracle Secure Backup configuration object that specifies characteristics of
Recovery Manager (RMAN) SBT backups. The storage selector act as a layer between
RMAN, which accesses the database, and the Oracle Secure Backup software, which
manages the backup media.
dataset
The contents of a file-system backup. A dataset file describes a dataset. For example,
you could create the dataset file my_data.ds to describe a dataset that includes the
/home directory on host brhost2.
dataset directory
A directory that contains at least one dataset file. The directory groups dataset files as
a set for common reference.
dataset file
A text file that describes a dataset. The Oracle Secure Backup dataset language
provides a text-based means to define file-system data to back up.
defaults and policies
A set of configuration data that specifies how Oracle Secure Backup runs in an
administrative domain.
device discovery
The process by which Oracle Secure Backup automatically detects devices accessed
through Network Data Management Protocol (NDMP) and configuration changes for
such devices.
