File changed during save....

[roland]

hi!

i want to use rsync for backup to central storage.

from emc networker i know some nice feature - it`s telling about "changed 
files during save" - i.e. i
know which files have changed their contents while being backed up. for 
example you can see if
shutdown of some oracle database was forgotten and that database was backed 
up online accidentally.

what`s the rsync equivalent to this?
how can i see which files changed while rsync was transferring them ?

i get some "rsync warning: some files vanished before they could be 
transferred ....." from time to time....

any hints how to see some more details here to know which files being at an 
probably inconsistent state on
the mirror side ?

regards
roland
