Great for systems with lots of files.. Ran some tests backing up a win2k
server with a million files before and after journaling option was enabled.
Without it enabled it took an hour just to scan through the directory
structure even if nothing needed backing up. With it enabled, the hour-long
backup took less then 5 minutes.. Haven't run into any problems using it
myself but I can't say I've used it extensively (just on a server with lots
of files).
