Hi teera,
Check "man .netrc" how to install some automatic FTP script.

You probably should use a two-stage cron script:

1. A script which creates the backup file

(like with:
find $HOME -type f -mtime -1 > ~/newfiles
tar -cf - --files-from ~/newfiles | bzip2 -9 > newfiles.tar.bz2
mv newfiles.tar.bz2 newfiles_ready.tar.bz2

Instead of $HOME you can use any other folder. bzip2 is very efficient, but also a bit slow. If speed is an issue, use gzip -1 instead.
)

2. An FTP script which simply uses "ftp backup", which will then use all the settings you defined in .netrc

-> This is still quite crude. There are better ways, such as using rsync via ssh. But you'll probably want a working solution first before refining it.


Cheers,
Stefan

You can also use wget to retrieve the files from the ftp server. wget should be part of any major Linux distributions.

Here is a easy sript based on  stefans code:

#!/bin/bash
tar -cf - (the name of the dir to backup) | bzip2 -9 > newfiles.tar.bz2 && mv newfiles.tar.bz2 newfiles_ready.tar.bz2 && ncftpput -u (username) -p (password) (remote-host) (remote-directory) newfiles_ready.tar.bz2
# End script

ncftpput is part of ncftp, which may not be installed automatically (or may not be part of your distribution at all).

ncftp but its part of most distributions, and then how do you use wget to put files ?

Karl Heinz KremerCommented:
You run wget from the machine that receives the files. If you need to put something on a ftp server, you need wput (which is a seperate project, and not part of most distributions).

You could have the server "pull" them instead of the client "pushing" them. But you're right, this is probably less efficient.

The only reason to use this is security considerations. If the client is considered "unsafe", it's better to have the server get the file.

The question did not say which directions the files need to be moved. I just assumed that something on the server needs to be backed up. But you are right, it could be the other way as well.
