    I really like this post, but i guess you had missed something important here,public key,…
    usually i don’t encourage anyone doing serious work like back up, to blindly use a third party repo, without checking and verifying the public key,…
    with respect to fedora 19,..i did the following before adding this repo to my /etc/yum.repo.d/

    1- download the afio.repo & afio.pubkey
    2- Copy the afio.repo to /etc/yu.repo.d/
    3- Copy the afio.pubkey to /etc/pki/rpm-gpg/
    4- Get the fingerprint of the afio.pubkey:

    [root@omar ~]# cd /etc/pki/rpm-gpg
    [root@omar rpm-gpg]# gpg –quiet –with-fingerprint afio.pubkey

    pub 1024D/37DB9883 2001-08-24 Bruno Cornec
    Key fingerprint = 54AA 7ADA 8C6B 0F5D 51C7 5DC0 141B 9FF2 37DB 9883
    uid Bruno Cornec
    uid Bruno Cornec
    uid Bruno Cornec
    uid Bruno Cornec
    uid Bruno Cornec
    uid Bruno Cornec (primary address)
    sub 1024g/7ADE3ADA 2001-08-24
    [root@omar rpm-gpg]#

    Now, we can check the above key on https://pgp.mit.edu/ public key server, to match the fingerprint
    You can use, the key name and e-mail address “Bruno Cornec ” to get the public keys for that name and e-mail address, and enable “Show PGP fingerprints for keys”.

    After verification of the fingerprint, now you can safely import this public key to your rpm database:
    [root@omar rpm-gpg]# rpm –import afio.pubkey

    4- Edit the afio.repo file as follows:

    [root@omar ]# cd /etc/yum.repos.d/
    [root@omar yum.repos.d]# vi afio.repo
    [afio]
    name=fedora 20 i386 – afio Vanilla Packages
    baseurl=ftp://ftp.project-builder.org//fedora/20/i386
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/afio.pubkey

    Save & Exit

    5- Do the same thing for buffer, pb and mondorecue repos and pubkey.

    That is it,….
    One more time,..thank you for your post,…i really enjoyed it,…

    6- Install mondorescue as follows:
    [root@omar]# yum install mondo

    Hi Ravi,

    Can I use the iso backup of one server to restore onto another server (rather than installing it).Or every servers iso backup can be used to recover only that specific server.

  3. Marcon says:

    Hello,

    Can this be used if I want to ‘clone’ my current Centos server setup to other machines?

    Cheers.

    • Ravi Saive says:

      Marcon,
      May be yes, but I never tried it, I think you should give a try..let me know when you’re done..

  4. shairalibaig says:

    shall we create a script for this to automate /or to take the full image backup of iso image once in a week..

    • Ravi Saive says:

      @Shairalibaig,
      No idea about shell script, but you can use rsync or dd command to make full system backup..

  5. shairalibaig says:

    yes can i do it for centos 6.5 production server

    • Ravi Saive says:

      @Shairalibaig,
      Yes, you can use these instructions on CentOS 6 or any CentOS flavors to take backup/restore..
