Hello,
Why using tar ?
In attachment, you will find a short collection of scripts.
archive.sh and dump.sh work. I don't remember the status of
backup.sh and dump2.sh which should work with few modifications. The
main idea is to split the partition to be archived into slices of 650
Mo: that's why afio is used.
In that way, it is possible to restore an archive, a.k.a
a set of cdroms containing archive1-FreeBSD.afio to
archiveN-FreeBSD.afio.
Suppose you've got a wy to store mount_ufs and mount_cd9660
and afio. I put thr content of /stand/sysinstall + a lot of
/sbin/mount_* and a version of afio statically compiled in
a directory /winnt/freebsd. This directory is a FAT partition
(not an NTFS one). Simply boot with kern.flp, mfsroot.flp,
and enter a tty-4 shell with fixit.flp.
The do the following:
mkdir /winnt
mount /dev/ad0s1 /winnt [or mount_msdos /dev/ad0s1 /winnt]
(the disk is supposed to be correctly labelled)
newfs -b 4096 /dev/ad0s3 (my partition containing FreeBSD)
mount /dev/ad0s3 /mnt
cd /mnt
mkdir /cdrom
/winnt/freebsd/mount_cd9660 -o ro /dev/acd0c /cdrom
/winnt/freebsd/afio -ivk /cdrom/*
umount /cdrom
Do the same procedure for your CDROMs archive2-FreeBSD.afio
to archiveN-FreeBSD.afio.
Once you have finished:
umount /mnt
exit (from the tty-4 shell of fixit.flp)
In the /stand/sysinstall menu :
Configure => do a post install of FreeBSD
Fdisk => write to make the loader you have chosen active...
I use this kind of archiving for about two or three years.
Best regards,
Jean-Christophe Cazenave
PS: dump.sh works, but I don't easy the recover operation it involves.
