looking for a linux image & backup tool / offline / RAID
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
also gui ' y if possible, have people that are scared of commandlines :)
bah since no one is replying, here is what i've put toghter...
Use a modify copy of the linux system rescue cd
Has the cciss drivers and usb drivers
Use a program like makeiso or the many other flavors floating around
Boot off cd, load application…
Write a simple script to dd each partition to an image file and dump it to the usbdrive.
_dd if=/dev/cciss/c0d0p1 of=/mnt/usbdrive/boot_backup.img
-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
