Catalog protection

What is catalog protection?
Data Protector saves information about backed up data in the IDB. Since the
information about the backed up data is written to the IDB each time a backup is
done, the IDB grows with the number and the size of backups. Catalog protection
tells Data Protector how long the information about backed up data is available to
users browsing data during restore. Once catalog protection has expired, Data
Protector will overwrite this information in the IDB (not on the media) in one of the
subsequent backups.
You can specify the protection using absolute or relative dates.
If you do not change the Catalog Protection backup option when configuring your
backup, information about backed up data has the same protection duration as data
protection. Note that if you do not change this, the IDB grows constantly as new
information is added with each backup.
For more information on how catalog protection settings influence the IDB growth
and performance, see
parameter" on page 201.
The protection model used by Data Protector can be mapped to the concept of backup
generations, which is elaborated in

Logging level

What is logging level?
Logging level determines the amount of details on files and directories written to the
IDB during backup. You can always restore your data, regardless of the logging
level used during the backup.
Data Protector provides four logging levels that control the amount of details on files
and directories written to the IDB. For more information, see
IDB key tunable

Browsing files for restore

The IDB keeps information about the backed up data. This information allows you to
browse, select and start the restore of files using the Data Protector user interface.
You can also restore data without this information as long as the media are still
