Talking looking for a linux image & backup tool / offline / RAID


hellos all.

I am trying to backup a bunch of mounts before migrating LAS2.1 to LAS4.0(nuking then complete re-install, copy customer's data back over) The drives are on a hp proliant server(dl385&dl585) running RAID 5.

My dream so far is.

1. Offline, boot off cd .

2. mount SCSI RAID 5 drives.

3. make a image from the diffrent mount points and dump into a usb drive.
ie: of=/usr/home if=<usbdrive>/backup/home.img

4. mount the drive later using the loopback interface from the <usbdrive>

ideas suggestions, any proggies out there that already do this?

I know its possible, i just dont know how

bah since no one is replying, here is what i've put toghter...

1.

Use a modify copy of the linux system rescue cd
sysresccd.org

Has the cciss drivers and usb drivers

Use a program like makeiso or the many other flavors floating around



2.

Boot off cd, load application…



3.

Mount usbdrive.

Mount /dev/uba1



4.

Write a simple script to dd each partition to an image file and dump it to the usbdrive.

c0d0p1 /boot

_dd if=/dev/cciss/c0d0p1 of=/mnt/usbdrive/boot_backup.img



5.

-After LAS4 is installed-

Mount usbdrive and use the loopback interface to mount the drive on new LAS install.

Mount /dev/sda1 /mnt/usbdrive ##use dmesg to find out what <dev> to use, usually sda1 on hp systems##

Mount –o loop /mnt/usbdrive/boot_backup.img /mnt
