dumping active file systems

[Roland Schemers III]

Hello! I have a question about using 'dump'. How dangerious is it to
dump an active file system? That is, dumping a file system that is
mounted, and while the system is in multi-user mode? I have gotten
various replies from DEC, ranging from "It might corrupt the whole dump",
or "Only the active files will be messed up".

For a monthly or weekly dump I see no problem with bringing the system
down to single user, but every day to do incrementals seems a bit
drastic.

ps. we are currently using opser, and doing daily (level 9), weekly (level 5),
    and monthly (level 0) dumps, bringing the system down to single user mode.
