Sync to WD MyCloudEX2

Posts: 4 · Bob306 27 Nov 2024, 20:07

Hi folks,
I've been using FFS since I migrated from Windows to Linux Mint in 2016 and find it both easy to use and reliable.

However, I need help with getting it to connect with a home cloud I have connected to my router. I have a WD 'MyCloudEX2Ultra' and I can access it form anywhere over the internet. I am sure it should be simple to set up FFS to backup with it but I seem to be at a loss on what exactly to type in the 'Target' address line.

I've searched the forum and found some discussion but these were asking questions beyond the basics with which I need help.

I would be grateful if anyone could please give me a few points.

Many thanks

Bob306

You should use its hostname or local IP address if you are on the same network

It looks like your NAS supports FTPS.

In the online storage box choose FTP and then be sure to check the box to use explicit SSL/TSL.

Hello again,
It's been a long time since I wrote my question, and I have still not succeeded in setting this up.
I am in France, my WD 'MyCloudEX2Ultra' is connected to my router at home in UK. I can access this via my laptop via a browser which shows "https://os5.mycloud.com/cloud/shares" in the address bar. I login to this using my email address and a password. I am also able to access this via the WD app on my phone.

My problem is I really need my laptop to be able to back up to the home cloud via FFS. In the setup I used the 'Cloud' icon and as suggested selected FTP, and SSL/TLS . I have tried all variations of the line 'os5.mycloud.com' and also tried the 192.168 etc IPv4 address.

I guess I don't really understand the protocols required here and have missed something quite basic. Any pointers would be greatly appreciated. Thanks, Bob.

Sftp which is what you're probably trying is not supported by your storage device so you have to follow the instructions for ftps or regular FTP.

The WD My Cloud EX2 Ultra does not natively support SFTP (SSH File Transfer Protocol) out of the box. However, here’s what it does support and what you can do to get something close:

---

🔐 Native File Transfer Options:

1. FTP/FTPS – You can enable standard FTP and FTPS (FTP over SSL) from the dashboard settings.

Go to Dashboard > Settings > Network > FTP Access

Enable FTP (and optionally set up port forwarding on your router)

FTPS is more secure than plain FTP but still not as secure as SFTP.

2. WebDAV – It supports WebDAV, which works over HTTPS and can be used securely.

Go to Dashboard > Settings > Network > WebDAV

Enable WebDAV, and access using compatible clients over port 443.

---

❌ No Native SFTP Support

WD firmware does not include OpenSSH or an SFTP server, so you can’t use SFTP without modification.

---

🛠️ Workaround Options (Advanced Users)

If you’re comfortable with tinkering and understand the risks (like voiding warranty or bricking the NAS):

1. Install Entware or Optware (unofficial mods):

SSH into the EX2 Ultra (SSH must be enabled in settings)

Use Entware to install OpenSSH or Dropbear

This can add SFTP functionality, but it’s unsupported by WD.

2. Use an External SFTP Server:

Mount the EX2 Ultra to a system that runs an SFTP server (e.g., a Raspberry Pi, Linux box, etc.)

Share EX2 folders via NFS or SMB to that system, and serve via SFTP from there.
