another question about dump & restore

[Brandon S. Allbery]

As quoted from <5757 at umn-cs.cs.umn.edu> by indermau at dg (Kurt Indermaur):
+---------------
| In the man pages for restore, under "BUGS", is the sentence "Restore can get
| confused when doing incremental restores from dump tapes that were made on
| active file systems."  What is an "active file system"?  Nobody logged in?
| Single user mode?  
+---------------

A file system is active if it's mounted.  It *is* possible to dump a mounted
file system if you sync beforehand and make absolutely *certain* that nobody
does *anything* on the filesystem -- even "echo /being-dumped/*" can screw
things up, as the st_atime of the directory /being-dumped will be updated.
