1.12 What is the difference between the "DIRECTORY" and "STOREDIRECTORY" options?

DIRECTORY causes the MPE directory of accounts/users/groups and HFS directories to be written to the tape. This facilitates the recovery of accounts, groups, users and directories if necessary. Note that unless ONVS= is specified, only those directories on the system volume set are stored.

STOREDIRECTORY allows you to create a disk copy of the STORE directory of a backup. This is enabled by default when ONLINE=END is specified. The disk directory allows RESTORE to more quickly locate files on the backup. All STORE and TurboSTORE products have the ability to put a copy of a backup's STORE label and STORE directory into a disk file. This directory information allows RESTORE to more quickly determine where files are located on the backup, and to prompt users to mount the necessary media. The information in this file is also used to determine if a file being restored has after-image log data. A file will have after image log data if it was modified before the sync point during a 7x24 true-online backup. RESTORE must have this information before restoring files.

The filename used by STORE uniquely identifies the file and associates it with a specific backup. The file is placed in the store_dirs HFS directory in the HPSTORE.SYS group. WARNING: The HPSTORE group and the store_dirs directory do NOT exist on the system by default. You must create them, and set up the appropriate security, before using the STOREDIRECTORY option.
