Hi Michael, Most likely, these differences boil down to NTFS security permissions and registry data. This data is backed up during the snapshot phase. Both are stored with the snapshot, and the most recent snapshot from each volume is saved in the catalog. So your assumption is correct--there's more data being stored in your Retrospect for Windows catalog files. The Mac verion of Retrospect is unable to back up NTFS security permissions or Windows 2000 system state data. It is only able to get the NT/2000 registry with the aid of the Dantz Registry Backup Manager (REGMAN.EXE). We are planning to change this, but it's still a ways off. I hope this helps.
