backups with dump and rdump - best strategy?

[mike at hele]

Hi!

Recently we have received our Exabyte drive, and I want to use the little
marvel to make FS backups of 3 machines:
	- one with 300 MB has the drive connected to
	- two other (600MB and 1.2GB) are connected with TCP/IP

How is the best way to do backups
	a) when the systems can *not* be shut down
	b) no file system must be unmounted

How can I avoid data inconsistencies, when (r)dump work on active FSs?

Thanks
Mike
