Hi Kyle!

You may need to install additional packages once Cygwin has been installed. In the version of Cygwin that I’m using, I have to run cygwin\setup-x86.exe.

Then search for package “ssh” and under the “Net” category you should find “openssh”.

Good luck!

If you maybe have a copy of these files hosted somewhere or could advise on where I might find them, that would be greatly appreciated. (I’m still learning all of this so forgive me if the answer is obvious)

Thanks @Luuc, fixed!

When I run the the script I get two errors. once is Could not create directory ‘/home/username/.ssh’

It then says it cannot establish the authenticity of the host and comes up with a ECDSA key fingerprint and asks if I would like to continue. When Yes is entered it tells me that it could not add the host to the list of know host and then proceeds to upload files.

I am guessing I am missing something simple but for the life of me I cannot find it.

Help would be awesome.

Cheers,

Justin

Nic :Hi Rene. I haven’t had this problem yet (or haven’t noticed it with my files yet), but I was able to install iconv by doing the following: 1) Install ipkg (Possible instructions here http://forum.synology.com/wiki/index.php/Overview_on_modifying_the_Synology_Server,_bootstrap,_ipkg_etc#How_to_install_ipkg) 2) Make sure you have gcc and make installed: ipkg install gcc make 3) Download iconv-1.14.tar.gz: http://www.gnu.org/software/libiconv/#TOCdownloading 4) Extract: gunzip iconv-1.14.tar.gz && tar xfv iconv-1.14.tar 5) Configure and make: cd iconv-1.14 ./configure make && make install

This is brilliant, thanks Nic.

One, you can try to escape the space with the \ character. eg: My\ Documents

I’m not sure, but DOS globs (wildcards) might work too, so you could potentially swap the space with a question mark (?‘) eg: My?Documents

Hopefully one of those will work for you!

Kind regards, Jan-Paul

Also, make sure the line-endings are in Unix mode and that the file is in ANSI (not UTF-8) mode. Both of those have caused me problems before.

Thank’s for this great solution, it’s really working fast. I had some issue at first like BillB but it was because I tried not to use the root account. I ended using it and it works.
But I can’t use the validation-script, because I have the following error:

/root/.ssh/validate-rsync.sh: line 1: ?#!/bin/sh: not found
protocol version mismatch — is your shell clean?

If i had the line :

command=”/root/.ssh/validate-rsync.sh /volume1/backup/WIND”

In the authorized_keys file.
I can’t figure out why I get this error but It is certainly because of my config and not because of your script.
I checked the /root/.profile file and it seems ok (with /opt/bin and /opt/sbin in it).

If you have any clue it would be nice, for now I am using your script without the restriction to rsync.

Hi Rene. I haven’t had this problem yet (or haven’t noticed it with my files yet), but I was able to install iconv by doing the following:

Hi Markus,

Newer versions of Cygwin may not need that DLL. Does the backup occurr successfully or is it complaining about cygspp-0.dll being missing?

i am trying to get this mentioned dll file “cygspp-0.dll”. but have a real hard time to find it.
could you give advice, helping to locate it?
all the other files where as expected found after installation of the current cygwin setup.

kind regards
markus

Never mind…fixed it 🙂
Found a typo.
Thanks anyway.

You could use the built in encryption of the synology. When the share is mounted it will work as a normal folder in ssh.

I agree completely, and I’ve been pondering what the solution would be. It’d be nice to have the clients have their own keys that they could use to mount a filesystem (or a .TC filesystem file) before the rsync, and then unmount afterward. There’s always a trade-off between full-automation and security. Anything that is fully automated still has the possibility of being infiltrated and then that system could be used to infiltrate further.

Let me know if you come up with anything!

Great post!

One potential issue with this approach is that the backup data is stored in the clear on the DS. It would be interesting to consider ways to encrypt the backup with keys known to the client only.

.. WebDAV with a TrueCrypt virtual disk .. Not sure what performance would be like.

Hi Sebastien,

Yes, you should be able to simply enable rsync on the Synology and open the appropriate port on your firewall/router to forward it. This method uses the same thing, however, it encrypts the transmission over SSH.

is it possible to save ours computers to a remote DS in another way ?

rsync, webdav ? or anything else ?

thanks for sharing !

Sebastien
