trunk/rdiff-backup/CHANGELOG

+New in v0.9.3 (2002/08/01)
+--------------------------
+
+Added --sleep-ratio option after hearing that rdiff-backup was too
+hard on hard disks (thanks to Steve Alexander for the suggestion).
+Quick example:  --sleep-ratio 0.25 makes rdiff-backup sleep about 25%
+of the time.  Maybe this will help on bandwidth usage also.
+
+Fixed -m/--mirror-only option.
+
+Added --exclude-other-filesystems option.  Thanks to Paul Wouters for
+the suggestion.
+
+Added convenience field TotalDestinationSizeChange (total change in
+destination directory - mirror change + increments change) to
+session_statistics file.
+
+Handle a particular situation better where a file changes in a certain
+way while rdiff-backup is processing it.  Before rdiff-backup would
+just crash; now it skips the file.  Thanks to Scott Bender for the bug
+report.
+
+A couple interface fixes to --remove-older-than.
+
+Added some security features to the protocol, so rdiff-backup will now
+only allow commands from remote connections.  The extra security will
+be enabled automatically on the client (it knows what to expect), but
+the extra switches --restrict, --restrict-update-only, and
+--restrict-read-only have been added for use with --server.
