Backup before and restore after a broken dist-upgrade - what is the simplest way
Hi,
I am planning to dist-upgrade to Lenny from Etch. Obviously, I want to
backup before upgrade and restore should the upgrade fail for what ever
reason. I have my root/usr/var on raid1 arrays. I see that backup is
very easy. I drop my netinst CD, boot in rescue mode, mount the mdx
arrays and backup onto a free partition. After that I can upgrade
realtively in peace. However upon a failed upgrade if I want to restore,
is the restore as simple as the backup? I mean, is it as simple as drop
in netinst cd, boot in rescue, mount the mdx arrays, format the arrays,
and restore from the backup? I suppose I have to chroot and do a
grub-install in the newly restored subsystem. But is that all? This look
too simple, and I want to know if I am missing something.
Normally, I would not worry. But this is the first time I will be doing
a backup/restore of full system on raid arrays and I want to be thorough
with my plan.
BTW, I tried clonezilla and it did not boot (must be my motherboard).
Also I did not see any mention of raid on clonezilla docs. So I do not
want to go that way.
Regards
Ramesh
