A true image restore allows you to restore a directory to what it was at the time of a selected scheduled full or incremental backup. Files deleted before that time are not restored.
You may want a true image restore if you have
recently deleted unwanted files from a directory and now want to
restore the latest scheduled backup without having to delete these
files again. For example, suppose you are backing up the contents
of the SYS:\ABC\DOC
directory. A
scheduled full backup ran on Monday that contained the following
files:
•SYS:\ABC\DOC\FILE1
•SYS:\ABC\DOC\FILE2
•SYS:\ABC\DOC\DIRA\FILEA
•SYS:\ABC\DOC\DIRB\FILEB
•SYS:\ABC\DOC\FILE3
On Tuesday, a scheduled incremental backup ran that contained the following files:
•SYS:\ABC\DOC\FILE1
•SYS:\ABC\DOC\FILE2
•SYS:\ABC\DOC\DIRA\FILEA
On Wednesday, you run a user-directed backup that contains the following files:
•SYS:\ABC\DOC\FILE1
•SYS:\ABC\DOC\FILE2
•SYS:\ABC\DOC\DIRA\FILEA
•SYS:\ABC\DOC\DIRC\FILEC
•SYS:\ABC\DOC\FILE4
On Thursday, a scheduled incremental backup ran that contained the following files:
•SYS:\ABC\DOC\FILE1
•SYS:\ABC\DOC\FILE2
•SYS:\ABC\DOC\FILE4
On Friday, you need to restore your SYS:\ABC\DOC
directory.
If your policy did not have Collect true image restore information selected, the restored directory will contain all of the files that ever existed in SYS:\ABC\DOC from the last full backup to the last incremental. This restore would include the following:
•SYS:\ABC\DOC\FILE1
•SYS:\ABC\DOC\FILE2
•SYS:\ABC\DOC\DIRA\FILEA
•SYS:\ABC\DOC\DIRB\FILEB
•SYS:\ABC\DOC\FILE3
•SYS:\ABC\DOC\DIRC\FILEC
•SYS:\ABC\DOC\FILE4
If you perform a true image restore, files deleted before the last incremental backup would not be restored. Therefore, the contents of the directory after the restore would be:
•SYS:\ABC\DOC\FILE1
•SYS:\ABC\DOC\FILE2
•SYS:\ABC\DOC\FILE4
NetBackup does not provide true image recovery based on the time of a user-directed backup or archive. However, it does use the images from user-directed operations for a true image restore if they are more recent than the latest scheduled full or incremental backup. If you are overwriting the directory you are restoring, files that are in the directory but not in the true image backups will not be deleted.
To restore true image backups using the target method
The Restore True Image Backups menu appears. This menu is similar to the Restore Backup menu described in Using the restore backups menu.
It is usually best to leave the start date at the default unless you are restoring a version that existed before the last full backup.
Individual files will not appear and cannot be selected because true image restores are for entire directories.
When you are through selecting, type

message at this point, notify your NetBackup
administrator.The double-click updates the Restore (True Image) window to show the folders that are available for true image restores. Notice that the lists show only folders. Individual files do not appear because true image restores are intended only for restoring entire folders. To list or select individual files, use Restore from Backup.
If NetBackup cannot find any folders, click Search Folder in the Search Backups dialog. Also check the range of backups that you are searching (NetBackup History pane). If all of these settings are correct and no folders are found, ask the administrator to see if the NetBackup policy that is backing up your files and folders is configured to collect true image restore information.
By default, NetBackup restores the folder to its original location. For information on redirecting restores, see Redirecting restores using the NonTarget browser.
