Your experience sounds about like ours. I think we get just a little more average life out of a cassette than you indicate, but not a large amount. Actually, we've used some DDS-4 too with pretty much similar results. One thing though, the cleaning tape may increase the life of tapes, but frequent use can reduce the life of a drive. The cleaning tapes can cause increased head wear. We recommend only using them when really needed - write errors show up - and not on a regularly scheduled basis. But, this is true of DDS-2 and even original DAT. Keeping your drive and storage environment clean and as free of dust as possible is a more important thing to improve tape and drive longevity, I think. If your usage justifies the cost, you might want to consider DLT or LTO type drives. They handle the load with less failure and higher capacity and data rates. ////jerry > > Hope I helped, > --Brian > > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG] On Behalf Of Peter Erickson > Sent: Saturday, December 14, 2002 7:57 PM > To: freebsd-questions@freebsd.org > Subject: Tape Backup > > I am running Freebsd 4.6 and my dds-2 tape backup drive just died on me. > I am interested in moving up to a bigger capacity drive so does anyone > have any recommendations?
