Arno> Accordingly, bacula should back up this file. Correct, but if you move a directory then the files within it do not change ctime or mtime and hence will not be backed up. E.g. # mkdir -p test1/inner test2 # ls >> test1/inner/datetest # ls -l test1/inner/datetest # ls -lc test1/inner/datetest # sleep 60; mv test1/inner test2 # ls -lc test2/inner/datetest In fact, they probably shouldn't be backed up -- it is another variant of the problem with incr/diff restore not restoring renamed things correctly. __Martin ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
