They are put into your currently logged on users. The key is named id_rsa and the keyhole is named id_rsa.pub. Do not set a passphrase, as the passphrase will then be needed in the rsync command. SSH to the external server with an appropriate user that has access to the content that you would like to back up and use the following command:ДЇollow the instructions to have what I like to call a key and keyhole generated. LetвЂ™s get started on the external server! To exit and save the file enter: :wq and press Enter Go to the home directory of the rsync user that we created earlier:Д¬reate a folder that will be used to store SSH key generated information:Д¬reate an empty file called authorized_keys: While using this account, please be careful with what you type: Type the below command to start working as root. If it isnвЂ™t already active go to: Control Panel -> Terminal & SNMP -> Enable SSH service (As with rsync, I would recommend using another port than the default 22)Д¬onnect to your Synology NAS using your favorite SSH client (I prefer PuTTY myself) and the administrator credentials. Now, enable SSH access to your Synology NAS. This is going to be important because of what weвЂ™re going to do next. Then Scroll to the bottom and put a check mark in Enable user home service. If you have not set up home folders for your Synology users, we will have to enable it by going to The Control Panel -> User -> Advanced.

User Speed Limit Settings shouldnвЂ™t matter either and you can press Next and lastly Apply to create the user.

When assigning application permissions, find rsync (Shared Folder Sync, LUN Backup on supported models), allow it and press Next.

If that doesnвЂ™t matter to you, press Next

User quota settings only matters, if you would make sure that it can only take up a certain amount of space.

Now find the newly created share (NetBackup) on the list and give the user Read/Write access to it and press Next.

The user does not need to be part of any special group, so just put it in regular users group and press Next.

Call the user rsync (or whatever you would prefer to call the user) and press Next.

Go to User and press the Create button to create a new user.

Once again go to the Web interface and continue to the Control Panel.

Second step will be to create a new user on your Synology NAS to use specifically for rsync:

A new Share will be created automatically called NetBackup (This is where your backups will be stored).

Put a check mark in Enable rsync service (I would highly recommend generating a random port number for rsync activity to increase security).

Go to File Services and choose the rsync tab at the top.

Go to the Web interface and continue to the Control Panel.

You will also need to know how to setup port forwarding to allow access to your NAS.ДЇirst step will be to enable rsync on your Synology NAS: If that makes you uncomfortable, this guide is not going to be for you. This will require you to fiddle with your Synology NAS via SSH. In this article I will be explaining step by step, how you can perform a backup task using rsync from your external Linux server (Debian Stretch in this case) to your Synology NAS automatically and on a schedule.

This might come in handy, if your server hosting provider takes extra for backup, then why not just backup to your own home and save yourself a couple of bucks! If you, like me, have a Synology NAS at home, you might want to offload some files from your other servers as a backup.
