Well, if you are going to reinstall FreeBSD - from a CD and FTP? - then all you really need to back up are the working files you want to recover. If all you want are logs, most of those are in /var/log unless you have told it to put things elsewhere or have created some special logging utility. So, you might get by with just dumping /var. But, since you have the bulk of your space in /usr, I think maybe you are putting some useful stuff in there. So, you figure out where your valuable stuff is and back up those filesystems. ////jerry > > > > -----Original Message----- > From: Jerry McAllister [mailto:jerrymc@clunix.cl.msu.edu] > Sent: Tuesday, November 22, 2005 10:08 AM > To: Jean-Paul Natola > Cc: questions@freebsd.org > Subject: Re: Dump Help > > > > > Hi all, > > > > I'm trying to utilize dump to copy the entire disc to a network drive , so > > that in the event of hardware failure I can just restore to a new machine > > > > Here's the output of df > > Filesystem Size Used Avail Capacity Mounted on > > /dev/ad0s1a 248M 35M 193M 15% / > > devfs 1.0K 1.0K 0B 100% /dev > > /dev/ad0s1e 248M 12K 228M 0% /tmp > > /dev/ad0s1f 4.9G 651M 3.8G 14% /usr > > /dev/ad0s1d 248M 59M 169M 26% /var > > devfs 1.0K 1.0K 0B 100% /var/named/dev > > total 5.6G 745M 4.4G 14% > > > > here's the command I ran > > > > dump / -0aL -f /usr/home/H/bsd_bkp/1116 / > > > > it runs well it says dump complete > > > > but my file only turns out to be 37,314,560 bytes > > > > what am I missing , Ideally I would like ( I think I would at least) the > > WHOLE disk to be backed up.... > > The dump utility backs up by file system, not by drive. > You told it to back up the '/' file system and it apparently did. > (That was that final '/' in your command line.
