I have just got a MyCloud EX4 and the first step is to copy existing content from MyBook to MyCloud (both on the same gigabit router). I figure if the copy can proceed at 60 MB/sec it will take 16 hr or so, but if it can only go at 20 MB/sec it will take 48 hr.
I thought I maybe could use the MyCloud app on my laptop and copy off MyBook and paste on MyCloud but this does not appear to be possible - the paste is greyed out.
I could make a safepoint from MyBook to MyCloud but I am not sure what steps to take to make the safepoint copy become the operational NAS content, and also from something I read I think this would only go at about 20MB/sec
So I have tried the simple minded use of WIndows to copy from MyBook and paste in MyCloud. The transfer rate is about 7 MB/s. At this rate the transfer could take 6 days and tie up the laptop for all that time. If I do decide to use Windows then using robocopy would be better that copy & paste in File Explorer because it can easily resume after an interruption - and in 6 days or so interuptions can happen.
But there must be a better way that does not pass the files through Windows. I can turn on ssh and FTP on both MyCloud and MyBook. But the sftp client which is on MyCloud does not seem to support “get -r” so is of limited use. So now I am looking at smbclient - looks hopeful but I am a slow learner. More later.
Well, smbclient can move a nested folder of files and the speed seems to be around 18 MB/s. BUT all the file creation and modification dates are set to NOW, which really troubles me.
So, next my attention will turn to rsync - but that can wait till tomorrow.
Just finished a transfer of 220 Gb of digital photos (many around 3 MB). It took 9 hr 25 min which I figure is 6.9 MB/s. I ran rsync on the MyCloud and the command was like
rsync -avf root@Mybook:Photos Newfolder
Both NAS units are connected to a TP-Link Archer C7 gigabit router. Both appear to be in good health.
I would appreciate any suggestions that could improve the transfer rate>
Thanks for your response ArMak. But I don’t fully understand.
The Mybook has a USB 2 port on the back but I was thinking that was so you could add an external USB drive to the MyBook NAS. I do not see how the Mybook could be USB connected to the MyCloud. Am I missing something?
I have continued working with rsync and further copies show that I am averaging 4.6 MB/s. It’s currently been working for 1 day on a 2 TB folder of videos, and it looks like it will take a week to complete. :cry:
So that’s the bad news.
The good news is that rsync is a good tool to be working with. It preserves file creation and modification dates (and eveythiing). If the process is interrupted and you restart it it will not re-copy the files that have already been copied. If you get it running as a background process on the MyCloud EX4, you can take the laptop away and later bring it back to check the progress.
To get it as a background process I set up a pair of ssh keys and put the public key in MyBookLive’s .ssh directory. This is so it would not be prompting for a password. I have the rsync in a small shell script so it is quick and easy to run the same command again.
I would still love to hear any advice that could get me faster transfer rates.
