Readong the forum there are challenges which USB (3.0) drive works or does not work with the MyCloud to store safepoints,

I need to buy one and would prevent all the hasle with ones that do not work properly.

Thx in advance.

WD My Book Essential works great.  The My Book with encryption works as well, but recovery from dead hardware later on could be a disaster.

Thx.

What is abt the free space needed in percentage of the original ?

In other words if I have 50GB on MyCloud how much space take the Safepoint ?

The Safepoints creates essentially a mirrored, flat copy of the content, plus some index and system configuration information for restoration. So you can assume you need the same size as the data usage on the NAS. You can access the file copies as you would the original share (they are stored in a different folder structure, but you will see a folder per share)

I think WD has been updating their WD Cloud to work with most USB 3.0 devices however just to be on the safe side I also bought a 4TB WD MyBook to match my 4TB WD MyCloud.

On testing the USB 3.0 port I did discover that when I attached a Vantech Raid device I would get only 22MB/s writes and about 35MB/s reads. Swapping the Vantec for the WD MyBook gave me results of 40MB/s writes and 70MB/s reads. 

Just so you know, my Vantec connected locally via USB 3.0 read and writes > 120MB/s.

Definitely something fishy with the code if you ask me :stuck_out_tongue:

if drive not = wdmybook  then usb speed = slow 

Also did a quick safepoint test at the begining when the drives were filled with only test data. With a dozen movie files, I timed the safepoint to see how fast it would be to the USB 3.0 port.

I got 10MB/s backup speed.

If I used a PC to read from the WD Cloud then proceeded to write to the USB 3.0 device… 

I got 25MB/s 

Finally if I ssh into the WD Cloud and just use copy

I got 40MB/s

which is the same speed if I access the USB 3.0 device from the network giving me the impression that this USB 3.0 port has a limitation.

One last thing…

I configured the Vantec Raid to be 8TB NTFS which meant it GPT to see how well the WD Cloud would handle GPT NTFS… 

Amazingly, after reading and writing to the 8TB drive, it was perfectly fine without any data errors. 

Good Job Wd!!!
