Ftp using rsync

rsync

I use Windows 7 machine and Putty to connect to UNIX servers. I am required to FTP certain files from those server to my local windows machine. For this purpose I use a FTP client like FileZilla or WinSCP.

However, I want to create a script , that would:

Connect to unix server from my windows machine.
FTP file from certain directories to windows machine.
Terminate the connection after the FTP download is complete.
This should occur periodically.

I have installed rsync 3.0 and cygwin. When I enter the following command:

rsync -e ssh user@host:/remote_directory .

It asks me: Enter Securid PASSCODE:.
and I enter the password for the same, but I get the error:

sh: rsync:  not found.
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: remote command not found (code 127)
   at /home/lapo/package/rsync-3.0.9-1/src/rsync-3.0.9/io.c(605) [Receiver=3.0.9]

Please help me in understanding why I face this problem.

Use cURL instead. rsync won't do what you require.

Ftp – How to use rsync over FTP

You don't. rsync can't do that for you, it is a protocol of its own and doesn't work over FTP.

You might, however, want to try csync. IIRC it provides rsync-like behaviour over HTTP. I can't comment on whether it works over FTP, you'll have to try it.

Linux – Copying a large directory tree locally? cp or rsync

I would use rsync as it means that if it is interrupted for any reason, then you can restart it easily with very little cost. And being rsync, it can even restart part way through a large file. As others mention, it can exclude files easily. The simplest way to preserve most things is to use the -a flag – ‘archive.’ So:

rsync -a source dest

Although UID/GID and symlinks are preserved by -a (see -lpgo), your question implies you might want a full copy of the filesystem information; and -a doesn't include hard-links, extended attributes, or ACLs (on Linux) or the above nor resource forks (on OS X.) Thus, for a robust copy of a filesystem, you'll need to include those flags:

rsync -aHAX source dest # Linux
rsync -aHE source dest  # OS X

The default cp will start again, though the -u flag will "copy only when the SOURCE file is newer than the destination file or when the destination file is missing". And the -a (archive) flag will be recursive, not recopy files if you have to restart and preserve permissions. So:

cp -au source dest
