This is more of a 'how do YOU do it ancillary question'...
Obviously to get a decent system backup from within Linux you should be in
single user mode, or even quiesced completely (if you're doing CDL volume
backups, for instance).
What are people doing to get a given image into single-user mode (or shut down)
and then restarted in an automated way? Just curious because as
always, there's 10 ways to do something that achieve the same goal, and
comparing the various methods/philosophies might be of use to some.

Hi,
in *theory* you can do live backup of machines with journaled filesystems
(at least ext3) without any problem.
Linux will repair filesystems from journal after recovering your backups.
You need to be sure that there is no activity on the Linux machine, or you
might end with corrupted data. As an example, you can stop your Oracle
databases, backup, then restart the databases.
The backup will end beeing the in same state of a machine you re-IPL without
correct shutdown. It is not clean, but it will start in most cases.
