Default LVM Backup/Restore without Live/Rescue CD?


I've been reading the excellent howto on creating an LVM snapshot and backing it up, but I have a couple of questions.

Has anyone tried using fsarchive? Any benefits to that?

Has anyone tried to restore from within a boot init shell?

I would like to have a restore option in the GRUB config menu and do the restore from a boot init shell script. I created a new boot selection in the GRUB config file and added the kernel option to boot into a shell

______ kernel ... init=/bin/sh

I think I should be able to do the restore from here, but the LVM tools aren't fully installed, so I'm not sure how to mount/unmount LVM partitions. The lvm command doesn't seem fully functional. The commands /sbin/lvm and /sbin/lvm.static are available, but I'm not sure what to do with them.

Maybe there are some LVM tools I need to add to a custom initrd.img?

Any insights into doing this would be helpful.

Also, when I backup the / root system partition, can I exclude the /boot partition from the archive? /boot is a separate partition that gets mounted into /.

My HDD structure is like this

_____ /boot _____________ 200 MB
_____ /snapshot _______ 10000 MB
_____ /backup _________ 10000 MB
_____ /LVMGroup00
__________ /swap ________ 200 MB
__________ / __________ 10000 MB
__________ /DATA _____ 960000 MB

Thanks,

-Jerry
