How to transfer data from old My Cloud to new My Cloud EX2 Ultra

[NAS_user]

@EngProf

It’s been a particular beef of mine, and many others, that WD don’t provide software on newer MyClouds (such as EX2ULTRA) that allows direct file transfer to and from another MyCloud on the same local network. Safe point was great, but is not available on later MyClouds which cannot be accessed from the old ones. We don’t all have handy TB USB drives to use so Windows was my only option. It took 2 days. With a GBit network and two WD drives I expected direct file transfer. Bad job WD.

I have to agree with this.

It makes major file operations unduly tedious.

What WD doesn’t include on the My Cloud Dashboard is a “file manager” app to allow dragging and dropping of files like Synology NAS does with File Station in Synology DSM. Such a feature removes the computer from the mix when copying files within on the NAS or from one NAS to another NAS (provided one has mapped the second NAS to the first NAS) and generally means faster copy/move of files/data between the NAS devices (or within the NAS device).

. . .and I agree with this.

Filestation takes the users PC completely out of the equation. . .and I have found it quite effective. I have used it mostly for USB transfers to/from the NAS, but i also works well between a WD NAS and a Synology NAS.

Depending on the My Cloud model one can backup direct from one My Cloud model to another My Cloud model without having to use a computer to drag/drop files between them (or to a USB hard drive attached to the source My Cloud. See the following WD Knowledge Base Articles for more information on OS5’s Remote Backup feature and on which My Cloud models that feature is available on. Also included is the OS3 Safepoint backup to another location.

I believe this has it’s own flaws. Within the WD ExoSystem; I have done this using SSH to execute the necessary commands directly from Linux.

Yes using WD’s local or remote backup (or Safepoint for OS3 users) has its own flaws. One major one being the inability to use a single bay second gen OS5 firmware My Cloud as a remote backup target. WD set it up so the multi bay models can be backup targets for OS5 remote backups but not the single bay. Stupid. The other flaw is OS3 Safepoint just fails sometimes with no indication why so a user can track down and fix the cause. Frustrating.

The flaky Safepoint was the main reason I moved (at the time) to using a rsync with email notification script to backup a first gen single bay My Cloud to a USB hard drive. Even made a post about using rsync to back up that first gen single bay My Cloud to a Synology NAS. With rsync one can combine it with nohup command to have it run after shutting down or disconnecting the computer from the My Cloud.

How do I SSH copy my shares from the MyCloud drive to a USB drive connected on the MyCloud?

Its a similar process explained in your other thread to use rsync to copy from the My Cloud to a USB hard drive attached to the My Cloud. For example: rsync -rtvh --progress /DataVolume/shares/Public/ /var/media/<USB Share Name>/Public/ Or use a SSH GUI program like WinSCP (for Windows, likely similar programs for Mac) to copy the files from the My Cloud to the USB Share. Just note that it may not be much faster (if at all) to use a USB drive due to the general slow nature of the USB port us…

Rsync to Synology Drive

Update: Using the following settings on the Synology DSM does allow me to rsync from the My Cloud (first gen single bay) to a Synlology NAS. Access the Synology DSM (I’m running DSM 6.2.3-25426 Update 2) and navigate to Control Panel > File Services > rsync. Select Enable rsync service. [Screenshot_2020-09-02 DS218Plus - Synology DiskStation] I went an extra step and made sure to use a Synology user (name) who has administrator group privileges and who has read/write access to the Share on t…

Problem is, using SSH/rsync typically requires some extra computer knowledge and skill to get working properly. Not everyone wants to go geek like that and want something much simpler and familiar like Windows File Explorer or Mac Finder, hence File Station in the Synology DSM NAS operating system.

Having had the same challenge, I found this thread and tried the rsync approach. However, transferring 1.4 TB of data with rsync would run for days and was still far from finishing. I think that’s due to the fact that I use my WD drive for Time Machine Backups, and they consist of thousands of smaller files.

I tried other approaches, and eventually came back here to report what worked fastest and best for me: using tar and scp. This is how you do it:

1. Activate ssh on both devices

Login to the UI, and under Settings > Network, switch on SSH.

2. ssh into the old device

ssh sshd@device-name

3. cd to the data folder, for example

cd /shares/TimeMachineBackup

4. Create a tar archive of the files and directories that you want to transfer. Use nohup, so you can logout and let tar keep running

nohup tar -cvf archive.tar file1 file2 directory1 >tar.log &

Note that I don’t use compression, because most files do not compress well, and tar turned out to be significantly faster without compression.

5. Wait till tar has finished. This can take hours. You can check if it is still running using

ps aux | grep tar

6. ssh into the new device

7. Copy the archive over, again using nohup to keep it running

nohup scp sshd@new-device-name:/shares/TimeMachineBackup/archive.tar /shares/TimeMachineBackup/ >scp.log &

8. Wait till scp has finished. This again can take hours, depending on the file size. You can check if it is still running using

ps aux | grep scp

or you simply check the file size on the new device using

ls -alh archive.tar 

9. Now unpack the archive, again you might want to use nohup, because it takes a while.

nohup tar -xvf archive.tar >tar.log &

10. Finished.

You’re ready to use the new device.

It would be quicker if you output the tar file to the new device. This would save the step of having to transfer the tar file after the tar command was done.

[Metin]

Nice idea. Didn’t think of that option, tbh. Actually, didn’t know that tar was capable of doing so. You might want to post instructions how that could be done.

[rac8006]

something like

nohup tar -cvf new-device-name:/shares/TimeMachineBackup/archive.tar file1 file2 directory1 >tar.log &
or you could mount the new device on the old device.
mkdir /transfer
mount -t cifs //192.168.1.209/shares/TimeMachineBackup /transfer
nohup tar -cvf /transfer/archive.tar file1 file2 directory1 >tar.log &
change the ip address to your new device ip address.
