Are you saying there's some tool that does the job right while the system is active? If so, please let us know! Otherwise, my statement is correct. That I didn't mention what should be common knowledge doesn't mean I wasn't aware of it. In fact, having to have the system down to do the post-installworld dump is part of the problem. If you don't back the system up, the buildworld/installworld path isn't to bad. But I rely on my systems for my livelyhood, and am not willing to put my data at risk that way. <mike On 23 Mar 1999, Dag-Erling Smorgrav wrote: > Date: 23 Mar 1999 18:38:03 +0100 > From: Dag-Erling Smorgrav <des@flood.ping.uio.no> > To: Mike Meyer <mwm@phone.net> > Cc: stable@FreeBSD.ORG > Subject: Re: Build of 3.1-STABLE failing? > > Mike Meyer <mwm@phone.net> writes: > > If you read the handbook on backups, you'll note that the recommended > > backup tool is dump - because it's the only thing that does the job > > right. > > Wrong.
