IRIX Checkpoint and Restart (CPR) offers a set of user-transparent software management tools, allowing system administrators, operators, andusers with suitable privileges to suspend a job or a set of jobs in mid-execution, and restart them later on. The jobs may be running on a single machine or on an array of networking connected machines. CPR may be used to enhance system availability, provide load and resource controlor balancing, and to facilitate simulation or modeling.
There's even an option to restart the process(es) after upgrading the OS.
Some caveats, the following system objects are not checkpoint-safe:
o network socket connections; see socket(2)
o X terminals and X11 client sessions
o special devices such as tape drivers and CDROM
o files opened with setuid credential that cannot be reestablished
o System V semaphores and messages; see semop(2) and msgop(2)
o memory mapped files using the/dev/mmem file; see mmap(2)
SWAT is a very nice point and grunt interface to Samba configuration. Follow the link "Global" and note each parameter has a "Help" link. Take a look at the documentation links too.
Assuming you are on the Linux box, access SWAT by pointing your web browser at http://localhost:901
and enter your root ID and password.

Of course, you need proprietary SGI hardware.
