I might point out that it sounds like your problem is with the Tape drives and not Retrospect. I have been installing secondary drives to be used exclusively for Retrospect backups for a few years now and Retrospect works just fine backing up to another drive and will even span multiple drives if needed. I also have the Prosoft Backup and I use it in occasionally for clients with limited skills, but for business environments I use Retrospect exclusively. It does have a learning curve but once mastered the product is excellent. I use it on both Macintosh and Windows and have fairly well mastered the interface and operational procedures. It is sort of like Microsoft word, one never really stops learning a product with this much power, you just get progressively better at using all it has to offer.
