Ignoring the problem of software recovery for a minute, How do you plan on getting the new hardware onsite and installed once it does fail?

You can certainly use dd across a network, just omit the 'of=' parameter and stream it somewhere (probably over ssh and to a file on a central system).

Flash archives are effective for this sort of thing too.

However, I would think that solstice disk suite (aka solaris volume manager, aka logical volume manager) to mirror between your two internal IDE disks would be a better option. Can you reduce your usage to only one disk? If so, you can mirror to the second disk. That way a disk failure won't even stop the server. Then, at your leasure, when you have a suitable time to have an outage, arrange for Sun (or an engineer you trust) to come onsite with a new disk. One the disk is replaced, the server is booted back up and it's easy to remotely reestablish the mirror again.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.

       See attributes(5) for descriptions of the following attributes:
