What is the best way to clone a hard disk over the network?
Is this idea feasible? If yes, then what is the command or program to
do that?
Boot the computer to "rescue" mode, then mount a network disk with
NFS, then run a command or program to clone a hard disk over the
network.
My computer is:
HP-UX B.11.31 U ia64

In article <cbc15912-dea6-41f7...@k13g2000hse.googlegroups.com>,

Hello TsanChung,

I have used "rsync" (available from hpux.cs.utah.edu) with success.
/usr/local/bin/rsync -avz --delete remotehost:/mountpoint/ /mountpoint

Also Ignite-UX from an Ignite-Server for root disks.

Yours, Hans Schwengeler

Do you really want to clone a disk, or do you want to clone a filesystem? In
both cases, there should be no updates on the source while the copy is in
progress, because otherwise your copy is more or less worthless.

I want to clone so that when there is any disk error on my current
disk, I can restore the cloned disk image to a new disk. Is that
clone a filesystem?

TsanChung,

I'm a bit confused by the question - what type of networking are you
trying to involve - SAN? Ethernet? Are you talking block-level
storage? What type of data - system data? Database filesystems? How
much expense can be considered?

We could take a number of paths depending on the particulars of what
you are attempting to accomplish... from RAID to iSCSI mirroring to
NFS snapshots to business continuance.

More details may prove helpful!

Cheers,

If you want to do the network clone,
lots of problems wil come out.
It would be easy to clone the whole partition or disk data to other PCs.
But if you want to propagate the system to other clients,
you need some preparations.
I know an APP called PC Network Clone.
It can realize most of the jobs of cloning by LAN.

It also has some lessons about how to make use of it. :)
