Some files within your storage environment can obviously be discarded, but how do you know which files to keep?

How do you know what kinds of files are being stored, their ages, and who owns them, so that you can clean out your storage space?


You could use a feature within Storage Manger , the storage performance monitoring software, called File Analysis. File analysis lets you determine the age, type, and ownership of the files stored across all your servers, virtual machines (VM), and network-attached storage (NAS). You can setup rules for file analysis on physical servers and have it run on a scheduled basis. The output provides reports which can then be shared with others. Storage monitoring simplified!


When File Analysis runs, it will look at the meta data of the file and not the contents.  It can place a load on the system while it runs, generally 15-20% of CPU, so generally it’s best to run file analysis at night outside of any backup window.

After file analysis runs, you can review from the summary file analysis all the files on that server. By default, you will get summary by file type, file age and owner. You can then drill-down from the array, server, or VM to a single file to find more information. File Analysis will also locate orphan files, files created in the last 24hours, and identify your largest files.

Here in the example below you can see all the MP3 audio files.


So with this information you can summarize your files and find specific ones you might want to take an action on.  Some common use cases:

  • Find all MP3 or any other unwanted files
  • Find all files over 1MB and not accessed in 1 year
  • Find all PST files
  • Find all Justin Bieber music files. This can be done using RegEx expressions to locate any files of interest.


In summary the File Analysis feature in Storage Manager provides analysis of file type, size, age, and owner. After you have this data, you have the ability to reclaim storage by removing old or unwanted files, storage performance monitoring has never been this easy. You can also enforce company file policies by identifying MP3 files or mpg, etc…
