I need to recover some disk space on a fileserver that uses raid level 5 disk arrays. I want to archive all files that haven't been accessed in the last 6 months. The BE administrators guide doesn't offer much detail regarding the file/disk grooming process. I would like to know how much drive space I can expect to recover but I don't see anything in BE that will give me any info. Does anyone know of any way to do this in BE, or any util that can do this calculation.
