7 How Data Protector operates
In this chapter
This chapter describes the operation of Data Protector. It explains Data Protector
processes (on UNIX) and services (on Windows), backup and restore sessions, and
media management sessions.
It is organized as follows:
“ Data Protector processes or services ” on page 219
“ Backup sessions ” on page 220
“ Restore sessions ” on page 225
“ Object copy sessions ” on page 229
“ Object consolidation sessions ” on page 233
“ Media management sessions ” on page 235
Data Protector processes or services
Data Protector runs several background processes (on UNIX) and services (on
Windows) that enables it to run backup and restore sessions. It provides the necessary
communication paths, activates backup and restore sessions, starts Disk Agents and
Media Agents, stores information about what was backed up, manages media, and
performs similar functions.
Inet The Data Protector Inet service runs on each Windows system
in the Data Protector cell. Inet is responsible for communication
between systems in the cell and starts other processes needed
for backups and restores. The Data Protector Inet service is
started when Data Protector is installed on a system. On UNIX
systems, the system inet daemon (INETD) starts the Data
Protector Inet process.
