Glossary
emergency boot file (Informix Server
specific term)
The Informix Server configuration file
ixbar.<server_id> that resides in the
directory <INFORMIXDIR>/etc (on
Windows) or <INFORMIXDIR>\etc (on
UNIX). <INFORMIXDIR> is the
Informix Server home directory and
<server_id> is the value of the
SERVERNUM configuration parameter.
Each line of the emergency boot file
corresponds to one backup object.
enhanced incremental backup
Conventional incremental backup backs
up files that have changed since a
previous backup, but has certain
limitations in detection of changes.
Unlike conventional incremental
backup, enhanced incremental backup
reliably detects and backs up also
renamed and moved files, as well as files
with changes in attributes.
Enterprise Backup Environment
Several cells can be grouped together
and managed from a central cell. The
enterprise backup environment includes
all clients located in several Data
Protector cells which are managed and
administered from a central cell using
the Manager-of-Managers concept.
See also MoM.
Event Logs
Files in which Windows logs all events,
such as the starting or stopping of
services and the logging on and off of
users. Data Protector can back up
Windows Event Logs as part of the
Windows configuration backup.
exchanger
Also referred to as SCSI Exchanger.
See also library.
exporting media
A process that removes all data about
backup sessions, such as systems,
objects, and file names, which reside on
the media from the IDB. Information
about the media and their relation to a
pool is also removed from the IDB. The
data on the media remains unchanged.
See also importing media.

term)

Transferring of the most important
