I wouldn't recommend that, unless you are maintaining a VERY small directory tree,
across a fast pipe. It takes a while to determine what, if anything, needs to be sent
by rsync. You'll end up with either a continuous reinvocation of rsync, if you wait
for one to finish before starting the next, or, if you invoke them asynchronously,
you'll end up in the far worse situation of having them cascading, stacking up on each
other, independently determining changes to be made, sending redundant changes,
slowing down finishing while new ones come along every 5 seconds (or whatever fixed
interval).
Have you considered writing a content promotion tool? instead of putting things into
the tree with cp or mv, you invoke this tool, which does the actual file move(s) and
invokes discrete rsyncs for each file. It'd fire off a recursive rsyncs for
directories, and non-recursive for files. if you're having changes made in place,
you'd have to determine a policy whereby users (or processes) are responsible for
kicking off their own rsyncs to propogate changes, or are required to use tools which
do
so. you might still want to run a full recursive rsync of the directory tree at
regular intervals, to preen the filesystem.

Subject:Re: keeping updating rsync
Classification:
If you run it fairly often, it won't have much data to move. It's not
going to be synchronous for all practical purposes, but you could
conceivably run in over and over with a 5 second delay, and it'd be pretty
close to synchronous.
What are you trying to do?

Is there anyway to keep update files from a host A to host B inmediatly???
How can I configure rsync to update speedly, like -RAID-??
Is it necessary to configure daemon??
