Backup does not save Network Drives/Data

I want to send a backup of my network data up to the IDisk as a backup and to have the access to the files when away from my network...It was suggested to use Backup...but Backup does not allow you to send network files...it comes up with a box that says you must move the files to the hard drive then send them up to the IDisk...

This seems like an additional step that becomes a bit of a pain...if I copied them to the hard disk...then why send them to the IDisk...

What I really want to do is make a copy of my data files directly on the Idisk....without having to copy them up individually....

Thoughts....

There are a myriad number of solutions to your problem, depending on your willingness to spend money or muck around with cheap alternatives.  Some ideas:

Dantz Retrospect Desktop can do backups of files on local area network www.dantz.com

Carbon Copy Cloner can clone one volume (presumably networked) to another volume (presumably iDisk). www.bombich.com

Some folks use psync from the Terminal; see http://www.macosxhints.com/article.php?story=20031029120418816 or http://www.macosxhints.com/article.php?story=20020711091017747

Seems as though there are no "easy" alternatives...I'm not sure if the Dantz pgm. is exactly what I am looking for...and have you used the other options...?

Also, if you can live with a simplified backup system that copies a few known files, or a few known directories, you could use a command line executable like "ditto".  (ditto is better than cp for copying files under the OS X unix system, since it understands and preserves resource forks, a hidden part of many files).  A typical command might be something like:

% ditto -v --rsrc /Volumes/RemoteDisk/backupdir /Volumes/iDisk

for more on ditto, see http://www.hmug.org/man/8/ditto.html

If you want to get fancy, you can wrap it all up in a GUI interface using iHook: http://www.macupdate.com/info.php/id/9698

Personally, I use Carbon Copy Cloner.  It's pretty straightforward, and cheap; if you don't want to clone the whole remote disk you would need to manually knock off the other directories in the CCC GUI list (just takes a moment).  If your needs are modest, and you have the files you want backed up in a single directory, the ditto solution is probably an OK way to go, though you have to have a little bit of experience with the Terminal, accessing Unix.  I personally don't have iDisk, so I'm unable to test this directly for you; I have used ditto successfully between a firewire disk and my boot volume, however.

I should have been a little more explicit about ditto; it's a pain to type in a long command like that, so the smart thing is to make a script file.  Here's how you would make a script file (items in <> represent single key presses):

% cat >MyBackupScript.sh<return>
ditto -v --rsrc /Volumes/RemoteDisk/backupdir /Volumes/iDisk<return>
<ctrl-D>

ctrl-D is end of input to the cat command, which terminates and saves the line above as a script command. To run it, type

%sh <MyBackupScript.sh
