creating a disk image of a hardware raid

[listrcv <listrcv@condor-werke.com>]

Hi,

I´m looking for a kind of rescue CD I can boot from to create an image 
of the contents of partitions residing on a hardware RAID (3ware 7500-4) 
--- or to create an image of the whole RAID. The image(s) could be 
stored on a disk connected to the IDE port of the board (independent of 
the RAID controller) or transfered to a file server on the network.

The image(s) should serve as a backup copy from which the system can be 
easily restored. It is only needed as a one-time backup to be made 
before doing a dist-upgrade of the system.

Any recommendations are greatly appreciated.
