Thank you all on responding this mater. Well the situation is the hardware is wrecked! So the only thing that I = have is the content of all partitions available. The backup is a tar = uncompressed data. So I have the contents in a server. So the objective is to use a completely different hardware but with the = same kernel, same configurations, same partitions, etc. In that way, what I thought (but I don't know if it is the proper way) was to install a = minimum freeBSD (same version which is 6.0) with the following partitions and booting with F1 option: /dev/ad1s1b none swap sw 0 = 0 /dev/ad1s1a / ufs rw 1 = 1 /dev/ad1s1d /new_root ufs rw 2 = 2 /dev/ad1s1e /archive ufs rw 2 2 /dev/acd0 /cdrom cd9660 ro,noauto 0 = 0 Then migrate the partions that I have in my backup / -> to partition /new_root (/dev/ad1s1d) at the end this should be = changed to /dev/ad1s1a /archive -> to partition /archive (/dev/ad1s1e) The idea is to make use of the same swap partition, and of course if all goes OK the partition / of the minimum system is lost when bootManager = is changed to boot on /new_root. That is what I have in mind but I am not sure if it will work. I am new to FreeBSD and I am more used to red hat, still I am putting = some effort to change that :) Best regards and thanks once again Nuno -----Original Message----- From: Kevin Kinsey [mailto:kdk@daleco.biz]=20 Sent: quarta-feira, 19 de Dezembro de 2007 16:58 To: Nuno Gon=E7alves Cc: freebsd-questions@freebsd.org Subject: Re: Bare Metal Recovery FreeBSD How To Nuno Gon=E7alves wrote: > I am trying to do a Bare Metal Recovery from a FreeBSD 6.0 system to a > different Hardware. >=20 > I have a backup from all partitions of the affected system so I am = trying to > install a minimum FreeBSD 6.0 in a different hardware which I already = have > up and running.

Did the kernel have a lot of customization? A GENERIC kernel should boot on almost anything --- which is why "bare metal recovery" seems=20 a misnomer to me. If the hard disk survives, I simply stick it in=20 another box and rarely have any difficulties. If it doesn't, I do a minimal install with the desired final slice/partition scheme on=20 the new HDD, and simply restore(8) over the top. > What is your opinion on this? What should be the best approach ? Well, I don't know your exact situation, but OOTOMH, the partitioning scheme you mention seems like wasting a disk unless you want the final system to have only /, swap, and /backup. Which could be OK, I guess, but isn't the traditional BSD Right Way(tm). Also, I'd consider installing a newer release than 6.0, and only restoring the important stuff. Again, it depends on your situation. My $.02, Kevin Kinsey --=20 You have been in Afghanistan, I perceive. -- Sherlock Holmes, A Study in Scarlet
