$ I'm performing dumps on a Sun server with an Exabyte 8mm backup system.

It's not "supposed" to be a good thing, since you can lose some files
while you back them up, but it's the only way I do backups, and I
haven't had a disproportionate number of problems resulting from it.
That is to say that the benefit of not taking the system down seems to
outweigh the inconvenience of the occasional lost file.
