==Setting up Synology for rsync via SSH/RSH==
==Setting up Synology for rsync via SSH/RSH==
When using ssh no rsync deamon is used on the DiskStation. However you need to have a valid public / private key pair, so the DiskStation can recognize the Linux machine. Follow the following steps ([http://troy.jdmz.net/rsync/index.html adopted from here])
<b>ToDo</b>: Elaborate
 
<b>Generate they key pair</b>
 
<code>
mkdir ~/.sshkeys<br />
cd ~/.sshkeys<br />
ssh-keygen -t dsa -b 1024 -f ~/.sshkeys/diskstation-rsync-key
</code>
 
Generating public/private dsa key pair.
Enter passphrase (empty for no passphrase): [press enter here]<br />
Enter same passphrase again: [press enter here]<br />
Your identification has been saved in ... diskstation-rsync-key. <br />
Your public key has been saved in  ... diskstation-rsync-key. <br />
( where  ... stands for your directory )<br />
<code>
chmod 600 diskstation-rsync-key
</code>
 
If you want to connect without using a passphrase, you must not enter any passphrase when ask (just it the "Enter" key)
 
<b>Transfer the keys</b><br />
First, you will have to enable the "homes" directory" through your Synology web interface. (all "homes" are created under directory ''/volume1/homes/'')
Use your file manager (e.g. Nautilus) to navigate to <code>[YourUserName]@smb://diskstation/home/</code><br />
Create a directory <code>.ssh</code> and copy diskstation-rsync-key.pub there.<br />
Now open a SSH connection to the diskstation to continue:<br />
<code>
ssh user@diskstation [Enter password here]<br />
cd /volume1/homes/[YourUserName]/.ssh<br />
ls -l
</code>
 
If there is already a "authorized_keys" file you skip the first line of the following code:
 
<code>
touch authorized_keys<br />
cat diskstation-rsync-key.pub >> authorized_keys<br />
rm diskstation-rsync-key.pub<br />
chmod 600 authorized_keys<br />
</code>
You can restrict the use of this key for specific commands or IP addresses ([http://troy.jdmz.net/rsync/index.html see here]).<br />
Exit from the SSH session. Now you are ready to test the keys with the following command:<br />
<code>
ssh -i ~/.sshkeys/diskstation-rsync-key [YourUserName]@diskstation
</code><br />
If you get a ssh session without a password prompt the ssh connection using your new keys works.<br />
 
<b>Sample backup command</b><br />
<code>
rsync --recursive --copy-links --times --verbose  --progress -e "ssh -i ~/.sshkeys/diskstation-rsync-key" \<br />
/home/[localusername] [YourUserName]@diskstation:/volume1/homes/[YourUserName]/backup
</code><br />
This will:
* Connect through SSH to your Synology, using the set of key you previously created
* Copy recursively all from /home/[localusername] to your Synology, within /volume1/homes/[YourUserName]/backup directory (no need to create "backup")
* Copy referents to symbolic links
* Preserve ties from your files
* Show you the progress from copy (not useful if you are running it with a cron)
<b>TODO:</b> Explain a little more
