DSM-G600, DNS-3xx and NSA-220 Hack Forum

I also had a lot of trouble getting rsync for Windows running. I downloaded cwRsync but it seems to need Cygwin to run properly. I tried to use rsync like this from the command line in Windows:

rsync -Dlrtpv --delete e:\data p:\backup

where e:\ is my local harddisk and p:\ is the Samba share of the NAS. It didn't work because rsync obviously assumes that locations containing a ":" are remote. As not both, source and target can be remote locations, it failed doing the sync.

At last I wrote a small Python script doing similar work. Of course, it is not capable of doing all the stuff rsync can do and it is also not that band width efficient but it simply copies newer files from SRC to DST and removes files from DST that have been deleted on SRC. I use it als GroupPolicy / Logoff Script on Windows to back up all modified files to the NAS when logging off or switching off the computer.

If you're interested, its in the attachment.

I wrote a set of scripts to do what you're talking about--where the DNS-323 does all the work to do the backups.  It's available at http://backupnetclone.sourceforge.net/  The files are there, but I don't have installation instructions yet.  Not sure when I'll get the instructions up, but the basics are there.

I tried to create a file like described in step 3, but i get a warning that this file cannot be created.
I can create the file in another directory on my computer or in the root of volume 1 but then copying it to the specified folder is also impossible. The warning tells me i have no permission to the folder. Also with ftp i can't get the file in the right folder.

Anbanmba - Great to see it is working well for you.  I noticed blbrown had some code (search for "email") in these forums that may be adapted.  Perhaps get an email sent to you "saying the job has finished" and then having the log file which has been created sent as an attachment?

blbrown - Do you see this as a possibility for the email script you have created?

Cheers,
Chumby.

knireis - no idea why that is happening.  Can you reset the dns (either via the web-interface) or the hard boot via the pin hole at the back and then try to copy the file in?

I did the reset both ways, but no luck. I renamed the fun_plug.d folder and installed the funplug .3 again but again the same thing. Also i am not able to delete the renamed (fun_plug.d-old) folder, any idea how to do this? How do i remove the funplug completely and delete all the folders created by the funplug? I can then try again from a fresh start.

Thanks for that... it looks like the post you are referring to is this one:

Yep, my email script can definitely do as you ask--If you grab BackupNetClone (from http://backupnetclone.sourceforge.net/) there are two files that do the actual emailing.  Look in complete_email.sh and sendmail.sh (which is an updated version from the one in the forum link you posted).

BackupNetClone is basically a fancy script for the rsync steps outlined in this thread--it sends an email status after the backup is complete.  It even reports changed files and disk space remaining on the backup server.  Unfortunately, setup is not for the faint of heart because it also uses SSH.  The website lays out the basic instructions, but I'm still working on the detailed line-by-line instructions for how to get a whole backup system up and running.

If you email me (details on the website), I can send you the text files I have with all the raw commands that I used to set everything up--it's a bit messy but might help you past some of the installation hurdles.

Another thing to note about the email script I wrote is that it only handles simple SMTP servers--those with no authentication or basic username/pw authentication.  So Gmail, Yahoo, and others that require SSL won't allow BackupNetClone to send its status emails.  Anyone interested in getting SSL compiled natively for the DNS-323? 

Hi Knireis,

It is in the tutorial (towards the top).  After you have installed the fun_plug, have you been able to telnet in OK with PUTTY?

Cheers,
Chumby

The fun_plug.d folder and subdirectories were created from the fun_plug script
and fun_plug.tar file, which is run at startup, as the root user.  In order to access
these directories and files you need to connect to the DNS-323 as the root user.

You can access the DNS-323, as root, with telnet, and create the files with the vi editor.

Chumby did an excellent job of detailing the steps required in the first post of this thread.

What exactly are you having trouble with in the

   STEP THREE – Create a Scheduled Backup

section?

O.K. I think I see your confusion, The instructions in code box of the section

   1) After you have telneted into the dns323 and can see the # prompt, type in the following line of code:

    vi /mnt/HD_a2/fun_plug.d/start/editcron.sh

creates the file. 

When you issue the vi command with a filename (that does not exist) vi will
create a new blank file, with the name you input.

'vi' is a command line text editor, you should google 'vi editor' to get an overview of the 'vi' editor,
'vi' can be very intimidation for new users.

Also, the telnet server, setup by fun_plug connects as root.

Good luck!

Someone please help me out here.

On this line

/bin/echo "5 2 * * * /mnt/HD_a2/fun_plug.d/bin/rsync -rlptDv --delete /mnt/HD_a2 /mnt/HD_b2 >/mnt/HD_a2/fun_plug.d/log/rsync.last.log 2>&1" >> $CRONTXT

What do I add if I want to exclude a directory from the sync?

marmot74,

telnet in and type "rsync" at the command prompt.  You will get the list of all options that rsync accepts.  One of the options is:
--exclude=PATTERN       exclude files matching PATTERN

Also, a good web page to refer to is the man page:
http://rsync.samba.org/ftp/rsync/rsync.html

--exclude "foo/"  would exclude any directory called foo

Cheers,
Dave.
