IBM Tivoli Storage Manager Extended Edition, Version 7.1

Managing tables of contents

You can use several commands to manage different aspects of your data contents.

About this task

The SET TOCLOADRETENTION command can be used to specify the approximate number of minutes that an unreferenced table of contents (TOC) remains loaded in the Tivoli® Storage Manager database. The Tivoli Storage Manager server-wide table of contents retention value will determine how long a loaded TOC is retained in the database after the latest access to information in the TOC.

Because TOC information is loaded into temporary database tables, this information is lost if the server is halted, even if the TOC retention period has not elapsed. At installation, the retention time is set to 120 minutes. Use the QUERY STATUS command to see the TOC retention time.

Issue the QUERY NASBACKUP command to display information about the file system image objects that have been backed up for a specific NAS (network attached storage) node and file space. By issuing the command, you can see a display of all backup images generated by NDMP (network data management protocol) and whether each image has a corresponding table of contents.

Note: The Tivoli Storage Manager server can store a full backup in excess of the number of versions you specified, if that full backup has dependent differential backups. Full NAS backups with dependent differential backups behave like other base files with dependent subfiles. Due to retention time specified in the RETAIN EXTRA setting, the full NAS backup will not be expired, and the version will be displayed in the output of a QUERY NASBACKUP command. See File expiration and expiration processing for details.

Use the QUERY TOC command to display files and directories in a backup image generated by NDMP. By issuing the QUERY TOC server command, you can display all directories and files within a single specified TOC. The specified TOC will be accessed in a storage pool each time the QUERY TOC command is issued because this command does not load TOC information into the Tivoli Storage Manager database. Then, use the RESTORE NODE command with the FILELIST parameter to restore individual files.
