backup / disaster recovery for Linux
 
Now I've finally got all the bits and pieces correctly installed on laptp and desktop is there any DISASTER / RECOVERY software out there for HOME users -- preferably that writes to DVD's-- I Don't want tape backup. There's a lot geared to Professional Servers (or "Big Money") . In case of a system crash I don't want to re-install everything again -- it's a lot of work finding all the patches, and apps you've installed.
Anybody tried "Disk Imaging" type software -- such as Norton Ghost --- I know it works for 'DOZE partitions but what about Linux.

Thanks

Ghost is your best friend
 
Hiya,


I'm affraid i don't know any backup type proggies that work on linux & write to DVD's or anything like that. However i have in the past used Norton Ghost to image my systems. I'm pretty sure i did my redhat install some time ago and it work flawlessly. It would however depend on the filesystem you are using i think. But don't quote me on that.

Ghost will also burn to CDRW & DVD's

Below is what Symantec says about Norton Ghost 2003 - everything you wanted assuming you are using either ext2 or 3 filesystems.

* NEW! Writes images directly to hard drives and removable media, including many CD-R/RW, DVD+RW, DVD-RW, DVD-R, DVD+R, and Iomega® Zip® and Jaz® drives.


NEW! Writes images directly to supported USB and FireWire® (IEEE 1394) devices.

File systems supported
All FAT
ALL NTFS
Linux EXT2/3

Regards

Stewart

Now what has tape ever done to deserve your disdain? :-) (note: I'm a long-time tape user so please excuse my vain attempt at humor)

Seriously... One thing to consider -- if it isn't too late -- is to try and install your system so that you have software that's part of the operating system in one set of file systems and your other software, your home directory (or directories) in another set of filesystems. And keep your non-OS software and data on different disks than those where the OS is installed. At least that way, should you lose the OS disk/disks, your data is safe and you don't need to go through the time restoring that. And if you do need to restore the OS, you're at far less risk of having the installer wipe out your data. It also makes it easier to do OS upgrades or switch distributions if the OS is kept separate from the important data. (OK, steppting down from the soapbox now.)

If you're looking for non-commercial software to do this, it's probably already installed on your system : mkisofs and cdrecord. I've used it to burn directory trees onto CD-R (not DVDs; I'm not equipped for that just now). The commands I've used to do this are:
Code:

cdrecord -scanbus  [1]
cd /scratch            [2]
mkisofs -pad -R -T -v -o cdrom.iso <source-directory>
mount cdrom.iso -r -t iso9660 -o loop /mnt/testiso  [3]
cdrecord -v speed=10 dev=0,6,0 cdrom.iso

[1] note the output; my burner is device "0,6,0"
[2] or some place with enough room to hold the resulting ISO file
[3] you can skip the test mount once you get the hang of the procedure

Also, there might be GUI-based tools on the system that automate these steps.

Hope this helps a bit...

Good luck,
Rick

You should take a look at Partimage - it is opensource unlike Ghost.

There is also an interesting SF project at:
