Released in 2002 and benefiting from a sustained period of development and evolution, ArchiverFS is the most reliable, cost effective and simplest solution to congested file servers available. Crucially, ArchiverFS doesn't try to shoehorn files (or even pointers to files) into a database. Yet through clever use of features baked into the Windows OS and NTFS file system you get all the features you would expect.
You get lots of flexible options to control what you would like to archive (like file age, file type, file size, and more) as well as a choice or archival methods and different types of links that can be left behind when a file is archived (including completely seamless links that look like the original file).
What's more, as no database is required and your archive storage can be nothing more than a share on your network the costs to deploy the software are an order of magnitude less than anything else available. The free version does not time expire and can process and unlimited amount of data. The only limitation is a cap of 100 files processed each time a job runs.
