Using the LAN Storage Discovery Tool : Generating a LAN File Summary report
 
Generating a LAN File Summary report
A LAN File Summary Report provides a detailed view of the files on the LAN. Filters are also available so that it is possible to analyze a particular group of files.
NOTE:  The file summary results can generate a number of reports that describe the data trends on the LAN. One-click reports can be generated to HTML, CSV, and XLS files.
To view a LAN File Summary report:
1. On the Tools menu, point to LAN Storage Discovery, and then click LAN File Summary.
F1 Help: "Online / LAN File Summary"
2. Click Find. The following information is displayed:
 
Report
Description
Global view
An overview of the total files and size for the following categories:
• All files
• Duplicate files
• Duplicate groups
• Changed and new files
• Unchanged files
• Not accessed files
The changed / unchanged, new, not accessed are determined by the parameter ‘last n days’. The default is last 30 days.
Filtered view
This is similar to the global view. However, it is for each share based on the specified condition. This condition is the combination of the following:
• ‘Last n days’: to determine changed/unchanged, new, not accessed.
• Filter: like ‘*.c*’ on file name
• Duplication: Only the files with duplicates equal to or greater than the specified number will be counted.
• Share: Specify a group of shares to be considered.
Show Details
Show the detailed information of the files corresponding to the selected row from the global / filtered view.
Charts
Show the pie charts for the selected row from the global / filtered view. The charts could be based on size or file numbers for all categories (Duplicated, Unchanged, etc.).
Show Duplicates
Show all files that are duplicated with the selected file.
3. To view detailed information about the files, do the following:
a) Select a row in the global or filtered view, and then click Detail. The following information is displayed:
 
File List
Backup Set / Share Name
Name of the backup set or share.
Directory
Directory.
File
Filename.
Backup Time / Last Scan
Backup time (online files) or last scan time (LAN).
File Size
Size in bytes.
Duplication
Level of duplication of the file (e.g. 10 means ten duplicates of the file exist Online or on the LAN).
Duplicate ID
Each file is scanned and an ID is generated for it. Any duplication (multiple instances of the same file elsewhere on the LAN or Online) will be identified by the same ID.
Last Modified (LAN File Summary Only)
Time the file was last modified.
Last Accessed (LAN File Summary Only)
Time the file was last accessed.

Opens the Show Duplicates dialog box for the highlighted file. Allows you to view all the duplicates of a single file. Highlight a file in the list, and then click the Show Duplicates button.
NOTE:  The Details dialog box is limited to a maximum of 50,000 files. If the scan returns more than this number, the results are sectioned.
