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 IBM® Storage Protect database. The IBM Storage Protect server-wide TOC retention value determines 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 did not elapse. 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 are backed up for a specific NAS node and file space. By issuing the command, you can see a display of all backup images that are generated by NDMP and whether each image has a corresponding TOC.

Tip: The IBM Storage Protect 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 the retention time specified in the RETEXTRA setting, the full NAS backup is not expired, and the version is displayed in the output of a QUERY NASBACKUP command. For information about setting data retention policies, see Customizing policies.

Use the QUERY TOC command to display files and directories in a backup image that is 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 is accessed in a storage pool each time the QUERY TOC command is issued because this command does not load TOC information into the IBM Storage Protect database. Then, use the RESTORE NODE command with the FILELIST parameter to restore individual files.
