!!  [Redundant dumps don't buy you much]
!!Using tar instead of dump buys you extremely little. tar will skip
!!active files, which means they won't corrupt your backup. This is its
!!sole advantage, and its only an advantage over some versions of dump.
!!It will *also* skip files with names that are too long; depending on
!!the version of tar you are running, it may also exhibit various nasty
!!other problems dump doesn't have. On the whole, dump is safer.

What about find | cpio?  We do that here to backup 1.5GB to a single exabyte
during a "quiet" period on Sunday.  Multi-user, but quiet.
