Clone RedHat / Cent OS / Fedora Bare Metal Recovery

Clonesys is a Shell script that can be used to create an ISO image of your Linux system. It is not another tool that backup users files but a tool that can recreate "ex nihilo" a similar system on another hardware.

#wget http://www.trickytools.com/downloads/clonesys-1.4.0.tgz
#tar xvzf clonesys-1.4.0.tgz
#cd clonesys-1.4.0
#sh clonesys.sh

Managing Directory: /usr/lib/audit
Managing Directory: /tmp/clonesys/
Creating the file archive (Please wait): testmade
OK

STEP 9: Create the Initial RAMDisk image:
----------------------------------------------------------------------
Compute the initial RAMDisk size: OK (found 22356 KBytes)
Create the initial RAMDisk file: 38740+0 records in
38740+0 records out
39669760 bytes (40 MB) copied, 0.317524 seconds, 125 MB/s
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
9696 inodes, 9685 blocks
0 blocks (0.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=12582912
1 block group
32768 blocks per group, 32768 fragments per group
9696 inodes per group

Writing inode tables: done                           
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 38 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
OK
Loopback mount of /tmp/clonesys/iso/isolinux/initrd: OK
Copy initrd files: OK
Unmounting /tmp/clonesys/iso/isolinux/initrd: OK

Copy current Linux kernel under /tmp/clonesys/iso/isolinux directory: OK

STEP 10: Create the ISO Image:
----------------------------------------------------------------------
Do you want to enter a shell before making the ISO filesystem (y/n) ? Create the ISO images:
Preparing ISO image #1 (current archive=1, start size=10544)
Create the ISO image #1:
mkisofs: Warning: -follow-links does not always work correctly; be careful.
INFO:    UTF-8 character encoding detected by locale settings.
    Assuming UTF-8 encoded filenames on source filesystem,
    use -input-charset to override.
Size of boot image is 4 sectors -> No emulation
