Hi! I have several NetApp filers with close to 25TBs of user data stored on them (Best guess is that there is some 50 million files, but we aren't sure as our backup software only backups the current data set, not the snapshots). We are looking to consolidate down the environment given the latest storage capacities and thought I would ask the community here what tools that they used to understand what data needed to be migrate, what data needed to be destroyed, and what the data costs in terms of per user and department? We have the costing for the storage down to a per $ fee per MB/GB.
Any thoughts? We have tried some freeware and shareware programs, but they require weeks, if not months of personnel time to make sense out of the data that they collect. We are looking for a packaged solution.
Thank you for your help.
