Logs all detailed information about backed up directories (names,
versions, and attributes). This represents approximately 10% of all
detailed information about backed up files and directories.
Log Directories
No information about backed up files and directories is logged to
the IDB.
No Log
The different settings influence the IDB growth, the backup speed, and the convenience
of browsing for data to be restored.
Impact on performance
The logging level defines the amount of data written to the IDB during a backup. This
also influences the IDB speed, and therefore the backup process.
Logging level and browsing for restore
Changing the level of stored information affects your ability to browse files using the
Data Protector GUI during a restore. If the No Log option is set, browsing is not
possible; if the Log Directories option is set, browsing of directories is possible;
if the Log Files option is set, full browsing is possible but file attributes (size,
creation, and modification dates and so on) are not displayed.
Regardless of the logging level set, it is always possible to restore your data:
• Instead of browsing for your data, you can always manually select a file to restore
(if you know the name of the file).
• You can retrieve information about backed up data from the media.
Logging level and restore speed
The restore speed is approximately the same when the Log All, Log
Directories, or Log Files options are set.
If the No Log option is set, the restore speed can be slower when restoring single
files. This is because Data Protector has to read all data from the beginning of an
object before finding a file to be restored.
In case of a full system restore, the whole object should be read anyway, so the
logging level settings do not play an important role.
