Well, it's not insane. ;-) Things to consider: Do you want to be able to restore previous system states? Like that file you deleted two weeks ago and now need again? Depending on how long an archive you want, you'll need to save an appropriate amount of old dumps (tapes). And remember that as soon as a level n dump is overwritten with a new one, all level >n dumps depending on it are invalidated. -- 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
