We have a Windows 2008 R2 File Server with massive amounts of user data, that's constantly growing. Currently we are tracking some of the root level shares to get a better idea of where this growth is occurring, but we are looking for an automated solution that get's more granular. Something that will track file changes and report on a daily basis. I've run free tools like WinDirStat and TreeSize, but the issue is that there are tens of millions of files and several TB of data that the software either bombs out or does not complete. If I specify smaller subdirectories then it works, but then I have to repeat this dozens of times. If there is a software that can schedule reporting on different paths and ideally report on the deltas since the last report would be ideal. Any thoughts and suggestions are appreciated.
