How to transfer files from one NAS to another

Unread post by Briar Gallery » Fri Dec 01, 2017 1:43 am

I want to move some directories/folders from a DS716+ii to a DS916+. So far I haven't figured out how to make a network connection between the 716 and the 916 directly. I am able to move files by using one of my network computers and connecting it to the two NAS's - then running a Windows Explorer substitute (Opus) to make the transfers. Of course, the process is dreadfully slow. I'm sure it'd be much faster to first use Hyperbackup on the 716 and backup the appropriate folders to the 916; and then restore/copy the individual files from the backup set into folders on the 916.

But is there a simpler approach? Is there some way to have the two NAS communicate directly with each other and transfer files between them? Some of the jargon in the help files about setting up a network suggests such a possibility, but I've had no luck so far in my attempts to make one NAS aware of the file system on the other NAS. Most of the "networkese" in the manual is incomprehensible to me, so I've been quite stumbling around in the dark.

If the process is too complicated, or requires me to chop a path through too thick a tangle of new language and new ideas, I'll simply use the Hyperbackup route. But I thought to ask before embarking on that solution.

Thanks for any help.

You can use File Station on your destination NAS. In Tools menu you will find 'Mount remote folder > CIFS shared folder' option.

With that command you can target your source shared folder(s) on your 716+II model in this format:

Code: Select all

\\ip.ad.dr.ss\shared_folder
Enter your 716+ii credentials and click mount. After that you should have your remote connection shared folder listed in File station on 916+. From there you can copy paste/move data, initiate tasks and log out. Also in this scenario you will not need to use any other 'middle' device.

Speed will depend on your local speed, array configurations, number and size of files.

Many thanks! This is just what I needed to know. This morning Hyperbackup completed backing up to the 914 the folders I wished to transfer from the 716 - and I suppose that at this point it will be faster to extract the "hyperbacked up" files on the 914 than to transfer directly from the 716 using File Station. But of course the initial backup took about 8 hours - so in the future it will be much quicker to eliminate Hyperbackup from the copying process. And in general, I pleased to know how to connect my NAS's (I have 3) without using Directory Opus or Windows explorer.

I tried the method of mounting a remote folder, but there seems to be a bug.
I was copying video and photo files and, though they copied over ok, the metadata for "created" and "modified" dates were overwritten using the date I copied them over.
This is obviously not an acceptable solution.
If the NAS are on the network, I can drag and drop files from one to the other using my Mac, and the files remain intact. This is obviously a slow way to do this though.
Very frustrating and no help from Synology who keep pointing me to help files which don't answer my question.

Try and use Hyper Backup rsync single version method to retain meta

That is indeed an ugly problem. Moving files with File Station overwrites the time details. I didn't notice it before but in 6.2 it exists. I never had time to open a ticket to Synology about it.

How about using Shared Folder Sync? You can find it in the settings.

I tried this on exact the same NASes as you have and I think I get the correct dates?

File Manager>Tools>Mount Remote Folder...

Once mounted drag/drop to desired destination. Easy peasy for one-time transfers.

This is driving me insane!
I have had a support ticket open to Synology but, I'm still no further.

They sent me links to the articles I needed which I followed and I managed to set up a shared folder sync on my DS918+, meaning I could put a file in this folder and see it on the DS412+.
I did exactly the same thing in the other direction and I keep getting the error that I "don't have the user privilege to perform this task".

I simply want to copy files from my DS412+ to my DS918+.
It should be a simple operation but I've already lost hours on this.

Of course I can copy files/folders over when they are mounted, but I want to sync the files as I have over 5TB to copy over so I am trying to leave out the "middle man" (my Mac)
