I would recommend doing both moves in the same script, to keep them
sequential.
rsync the server to the local staging directory, then rsync the local
staging directory to the local destination.
Have the script save its pid in a file when it starts.
Before it writes its pid into that file, it reads the file (if it exists),
and does a ps on that pid to see if the earlier run is still going, in
which case it just exits, and will be tried again at the next 2-minute
mark.
#!/bin/sh
ps -p`cat pidfile` |grep `basename $0` && exit 0
echo $$ >pidfile
rsync -avz server::module localstage
rsync -av localstage localdestination

Subject: URGENT: Tricky rsync problem
Classification:
Hi all,
Here is the problem that I need to solve:
I have an ftp server that I wish to rsync the files from a directory on
the remote server to a local server and then when the files are complete,
move them to a public directory on the local server.
To move the files from the remote server, I successfully tried using the
following command:
rsync -avz ftp.servername.com::roush/inbound/* /localserver/directory
I am running this command from the local server. The command is correctly
moving the files from the remote to the local server. I am not sure I am
using the correct switches but it is working.
Here are the problems that I need to solve:
1. The rsync command must update the local files based on a cron entry
every two minutes. I can do this. I need to be sure though, that rsync
is updating the files with new data.
In other words, if the file is still coming into the ftp server, I need
rsync to move the additional data across to the local server until the
file is complete.
2. Once the files exist on the local server, the files need to be moved
into a public directory for local access, again via cron (the local rsync
directory is separate from the public directory). I envision running
rsync again with new parameters for the local move.
Here is the issue at this point. I do not want to move the files to the
public directory unless they are complete. The end user (public
directory) must never see an incomplete file.
I am a beginner at rsync and would appreciate any help with this problem.
Thanks,
