Hi -
I have a legacy (RH 7.2) system and need to make an image copy of the hard
drive. If this machine goes down (hard drive gone) there is no way for me
to rebuild the applications. Can anyone out there help please?
Many thanks in advance.

Have you looked into Mondo Rescue? <http://www.mondorescue.org/>
RHEL/CentOS 2.1 is largely based on RHL 7.2 with some enhancements from
RHL 7.3. You might be able to rebuild on CentOS 2 without issue. CentOS
is free. CentOS 2 ISOs are available at:
<http://mirrors.easynews.com//linux/centos/2/final/isos/>
If all else fails, you could download RHL 7.2 at
<ftp://archive.download.redhat.com/pub/redhat/linux/>
Hope this helps.
Barry

Hello Aleksandar,
Thanks for your quick reply.
As you say, there isn't much advantage of running SNTP vs. NTP.
And, probably, one could "simulate" SNTP by ntpd configuration
regarding accurary. Is this right?
However, unlike NTP, SNTP uses connectionless UDP, and this may be the whole
point.
Does a NTP server consider the provision of time synchronization service
to a SNTP client? Or a SNTP client needs a SNTP server?
Many thanks.
Best regards.

if you have enough space in local drive than give following command
dd if=/dev/hda of=bkp.img bs=1024
It will make a very big file name bkp.img.
in case of failure you can restore with
dd if=/path_to_bkp.img of=/dev/hda
will restore the image.
Be careful at the time of dd command server will be slow you do not need to
shutdown the server.
One can user ghost opensource ghost if you can down the server.
Few more options are remote dump , ftp , rsync etc can also be used.

Um, buy a small hard drive (the newest big ones won't be recognized
properly by the older machine's bios), put it on IDE2, shut the apps
down, and copy all of that (*eigh*, except for /dev....)

I reiterate: DO NOT TRY TO DO THIS WITH /dev - it will *never* end.
You'll be trying to "copy" devices, including, oh, /dev/null, /dev/true,
/dev/false, and on, and on....

May be true, but I do not face that problem.
But agree with you, boot in rescue mode and give this command.

But will this image copy? I need the entire operating system, everything
that will allow me to take the copy HD and just replace the working HD and
not go through any kind of special booting procedures.
