Glossary 285
exclude list
A list that designates files or directories to exclude from automatic backups.
expiration (image)
The date and time when NetBackup stops tracking a backup image.
expiration (volume)
The date and time when the physical media (tape) is considered to be no longer usable.
EVSN
External volume serial number. This is an identifier written on a media cartridge or
canister so the operator can identify the volume before inserting it into a drive or robot.
For labeled media, the EVSN must be the same as the RVSN (identifier recorded on the
media). For all media, the EVSN is the same as the media ID.
FastBackup
A special type of raw-partition backup that can be performed only on an Auspex client
(this option is available only for NetBackup DataCenter).
FlashBackup
A special type of raw-partition backup that requires the NetBackup FlashBackup
separately-priced option (this option is available only for NetBackup DataCenter).
flush level
Controls how often Netbackup clears its log files on a Novell NetWare or Microsoft
Windows client platform.
fragment
A part of a backup or archive image. NetBackup can be configured to divide images into
fragments when they exceed a certain size or span tapes.
frequency (backup)
How often NetBackup performs scheduled backups. For example, if the frequency is
seven days then backups occur once a week.
FROZEN media state
If a volume is FROZEN, NetBackup keeps it indefinitely and can restore from it but not
use it for further backups or archives.
