Image server across network

You could:

1)  Install a faster USB card in the PE2600
2)  use NFS and some disk space on another machine running Linux
   and send the data over the network interface
3)  use raid tricks to copy the current drive (if you are using raid)
  then take the copy offline before the update

Since USB 2.0 cards are cheap, if you have an open slot I'd 
go that way.  You could do firewire too, if your external drive
will handle it.

Subject: Image server across network

Greetings -

I have a PE2600 that I am scheduling some maintenance on (e.g., firmware

updates).  This is my only Linux box in my small office and is used
as a Samba file server for about 10 Windows clients.  Before I conduct
firmware upgrades I plan on making an image of my server so that it can
restored easily if anything goes bad during the firmware updates.  I
done this in the past by attaching a portable usb hard drive directly to
server, boot the server to a live linux CD, and issue a command such as:
if=/dev/sda of=/dev/sdb bs=8192 conv=noerror,sync.  Where sda is my
virtual drive and sdb is the usb drive.

The problem is that with my PE2600 the usb device is very slow (usb
and in order to image the entire 140 GB it takes about 36 hours.  I am 
wondering if there is a more efficient way for me to create my server
such as connect the portable usb hard drive to my desktop system (a new 
Optiplex 755 running Vista), which has a faster usb connection, and
the image across the network connection.  I use Putty and NX Client from

NoMachine to connect to the server from my desktop system, although I
also boot to a live linux CD at my desktop if necessary.  Is this a
option for what I am trying to do?  And can anyone give me some pointers
how I would go about doing this?  Thanks.
