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
“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. |
