activity.
file version
The same file can be backed up multiple
times in case of full backups and
incremental backups (if the file
changed). If the log level ALL is
selected for backup, Data Protector
retains one entry in the IDB for the

mirror copies are called first level
mirrors.

information on the names of the backed
up files. Typically, these files occupy
about 20% of the IDB, if filenames are
stored.
formatting
A process that erases any data contained
on a medium and prepares it for use with
Data Protector. Information about media
(media ID, description, and location) is
saved in the IDB as well as on the
respective media (media header). Data
Protector media with protected data are
not formatted until the protection
expires or the media are unprotected/
recycled.

media pools when they run out of media.
The media pools must be configured to
