Learned ones!
To overcome some crappy web design (two servers, load balanced, no
shared storage), I need to implement rsync to synchronise a directory
between two servers.
Trouble is, it's got to be a two way sync.
I.E. File uploaded to web server 1 (don't ask - I told you it was crap

You can run rsync twice on the one server
rsync -options server1:/dir1 /dir1
rsync -options /dir1 server1:/dir1
with the rsync options, you probably want

If you can time stamp when you do it.
Update server 1 with files > timestamp from server 2
Record new timestamp.
Update server 2 from server 1 with delete.
(i.e. fetch new files from server 2 onto 1, then sync server 2 which will
remove dead files that you have deleted. Server 1 is the b

If it were me I'd look at making something based on ionotify
Then scp the files between the servers.
(note you will need to check the remote side to see if the file exists
