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 :newbie: |
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...
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 |
