I would like to have a synchronized copy of one folder with all its subtree.
It should work automatically in this way: whenever I create, modify, or delete stuff from the original folder those changes should be automatically applied to the sync-folder.
Which is the best approach to this task?
BTW: I'm on Ubuntu 12.04
Final goal is to have a separated real-time backup copy, without the use of symlinks or mount. I used Ubuntu One to synchronize data between my computers, and after a while something went wrong and all my data was lost during a synchronization.
So I thought to add a step further to keep a backup copy of my data:
cron
a script with rsync
? could be?). I need it to be one-way only from A to B any changes to B must not be applied to A.Inspired by lanzz's comments, another idea could be to run rsync at startup to backup the content of a folder under Ubuntu One, and start Ubuntu One only after rsync is completed.
What do you think about that? How to know when rsync ends?
You can use inotifywait
(with the modify,create,delete,move
flags enabled) and rsync
.
while inotifywait -r -e modify,create,delete,move /directory; do
rsync -avz /directory /target
done
If you don't have inotifywait
on your system, run sudo apt-get install inotify-tools
