We are currently planning a large file server migration. Many of our file servers are very old and contain shares with data that hasn't been modifed in years (old departments and users etc), in this case we would like to consider not migrating the data or perhaps archiving or even deleting it. I need a tool, script or process for identifying shares (or folders) which contain data that hasn't been modified in a specified amount of time.
If the tool could be run against a server and generate some kind of report it would be most helpful.
These servers are frequently backed up so the tool would need to work with modified date rather than accessed date.
