    I have a debian perfect server setup and running. I want to add a slave HD to it and use ghost for linux for a redundant backup. Can someone please explain what I do affter installing the HD and reboot the server? What I guess I need is directions on how to prep the drive before I run ghost. Thank you for the help.

    I dont know about ghost but if you have identical disks you can use dd to mirror the disks
    Code:
    dd if=/dev/disk1 of=/dev/disk2

    backup server

    They are not the same size. I guess I will setup another server and use this setup. I just wish there was an easy way to backup and restore the whole hard drive. So I don't have to reinstall everything. Like a image and then incramental backups. I guess it is the database that has to be stoped, so it dose not get curuped. I guss this program will work for what I am talking about.

    Well after doing a dd you can then use rsync to keep the two the same.

    hard drive install

    I slaved the drive and ran the commad
    HTML:
    dd if=/dev/disk1 of=/dev/disk2
    it is telling me /dev/disk1 : no such directory. Do I need to format the drive?
    I tried to type dd at the command promp and now I can not get out of it. I can type on the screen , but it will not take commands. Help

    disk1 is supposed to be the device on your machine i just used that as an example.

    to see the disks you can run fdisk -l or dh -h

    prep drive

    I see that drive one is 61.4GB with patitions hda1 hda2 hda5 and the slave is 30..0 GB and is hdb. How do I prepair the drive to be used? I think it is formated for windows. (NTFS)
    I figued out how to setup the drive. I setup all 30 GB on one patition. Can I copy the first drive to the 2nd drive if the drives are diffrent sizes? Also what about databases? will they transfer ok?

    dd is a low level copy you dont have to do anything. The only requirement is that the drives are the same size, because it will copy even the partition layout.

    I guess I will setup another server and try and see what are the best and easy to use programs to backup files and databases for my websites. I guess I need something to create an image and then incremental backups. Thanks for the information Topdog. I learned some things from this post. If you have any suggestions as to what I might setup, please reply, but if not, thanks for your help.
