Inotifywait usage and exclude

They will be run one after another unless you background the rsync with a & at the end.

This will run them concurrently which is not what you want:

inotifywait -mrq -e close_write -e create -e delete -e move /var/www | while read file
do   
    rsync -av /var/www1/ /var/www2/  &
done

You probably also don't want it run ten times consecutively. This may be what you're after:

while inotifywait -rq -e close_write -e create -e delete -e move /var/www
do   
    rsync -av /var/www1/ /var/www2/  
done

Also, be aware that running inotifywait recursively on a large /var/www may take a while to set up on each invocation. You may want to limit its scope to only watching active subdirectories or just use cron to periodically run rsync.

Edit:

Try this demo:

$ mkdir inotifytest
$ cd inotifytest
$ echo something > testfile
$ while inotifywait -rq -e access .; do echo "processing"; sleep 3; done    # test 1

Now in another terminal, do this:

$ cd inotifytest
$ for i in {1..10}; do cat testfile > /dev/null; done

In the first terminal you should see "processing" one time. If you do the for/cat loop (which represents files being added or deleted in your directories) again, you'll see it again.

Now in the first terminal, interrupt the loop with Ctrl-C and start this loop:

$ inotifywait -mrq -e access .| while read file; do echo "processing"; sleep 3; done    # test 2

In the second terminal, run the for/cat loop again. This time in the first terminal you'll see "processing" ten times with a three second pause between each one (representing the time it takes rsync to complete. Now if you were to run the for loop several times in rapid succession you might be waiting all day.

OK, I've seen it: if you go to NetBackup Management -> Host Properties -> Clients

Select the Client.

Then Properties -> Windows Client -> Exclude Lists.
