Hi
Is there some sort of backup/restore utility that I can use to make backups using the CD-R on my machines? CD-R's cost about a dime each these days. That price makes that media much more attractive than investing in a big tape drive and tapes..
I've got 5 machines on my little network. Each has a 20 gig HD (or less). How about another machine with a couple 50 gig drives that would be used just for backing up the others? That would cost about as much as the tape drives and tapes.
Another strategy you'd care to suggest?
Thanks a bunch

Take a look at Gentoo it comes with partimage is a nice iso file you download and write to CD, boot up on it, run it to prompt and type partimage . When your've created the partition image files you write then to CD and restore from them. I've just learnt how to do it and it works, though I've only done it with ext2 partition, the manual suggests it works with all file systems but as I say I have only tested it so far with the one.
If anyone is interested I've written(for my own use) a help file.
John
I'm interested John. I've got a 40Gb WDC disk that's giving probs once or twice a month.
I keep on telling myself to take the time to back it up before it goes. It's the time I'm short on:o( A nice help file like that would be just the push I need:o)
TIA, HarM

Note
====
if you want higher compression them call partimage with
partimage -z2 for bz file creation
default is-z1 for gz file creation
--nombr will not backup the mbr
==============================================================================
===============
list of options
===============
usage: partimage [options] <action> <device> <image_file>
partimage <imginfo/restmbr> <image_file>
Options:
* -z, --compress (image file compression level):
-z0, --compress=0 don't compress: very fast but very big image file
-z1, --compress=1 compress using gzip: fast and small image file (default)
-z2, --compress=2 (compress using bzip2: very slow and very small image file):
* -c, --nocheck don't check the partition before saving
* -o, --overwrite overwrite the existing image file without confirmation
* -d, --nodesc don't ask any description for the image file
* -V, --volume (split image into multiple volumes files)
-VX, --volume=X create volumes with a size of X KB
* -w, --waitvol wait for a confirmation after each volume change
* -e, --erase erase empty blocks on restore with zero bytes
* -m, --allowmnt don't fail if the partition is mounted. Dangerous !
* -M, --nombr don't create a backup of the MBR (Mast Boot Record) in the image
file
* -h, --help show help
* -v, --version show version
* -i, --compilinfo show compilation options used
* -f, --finish (action to do if finished successfully):
-f0, --finish=0 wait: don't make anything
-f1, --finish=1 halt (power off) the computer
-f2, --finish=2 reboot (restart the computer):
-f3, --finish=3 quit
* -b, --batch batch mode: the GUI won't wait for an user action
* -y, --nosync don't synchronize the disks at the end of the operation
(dangerous)
* -sX, --server=X give partimaged server's ip address
* -pX, --port=X give partimaged server's listening port
* -g, --debug=X set the debug level to X (default: 1):
* -n, --nossl disable SSL in network mode
* -S, --simulate simulation of restoration mode
* -aX, --automnt=X Automatic mount with X options. Read the doc for more details
* -UX --username=X Username to authenticate to server
* -PX --Password=X Password for authentication of user to server
