Okay, at home it only has to suffer weekly backups or so. But considering that I have never cleaned it... I would expect current generation QIC drives (Tandberg only I'm afraid) and DLTs to be reasonably robust, too.

One DDS drive every two years, right? How many cycles for each tape? 10? 20 if you're reckless? -- Christian "naddy" Weisgerber naddy@mips.rhein-neckar.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
