Clonezilla sounds like a good option

Do u reckon it would be important that the backup drive is the same size?

I am going to try from 1tb to 750gb

Gosh this site is riddled with adverts smh

That should be an issue. In general, Clonezilla should work because it can make a 1:1 copy of a HDD's sectors. If you want to copy a disk to another smaller disk, you first have to resize a disk's partition to a size the smaller disk can hold, and then do not copy the whole disk but just the partition.
The problem now is that the WiiU is using a closed-source, proprietary file system (which is why it does not get recognized by Windows or Linux), and you cannot resize the partition on the WiiU disk to a smaller size (would be gladly surprised if that is possible).

Long story short: In case of the WiiU, I guess you can only do a 1:1 copy to a disk of equal (or bigger?) size. Since you cannot access the data as such, I see no possibility of performing a file sync. Still, you can do a workaround of that problem using DumpsterU.

edit:
In any case, that is the image of Clonezilla:

thanks so I found another the same sized hdd lying about and will attempt the clone via clonezilla.
think it puts one in a better posisition should the original HDD Die. At least won't need to copy all of them games back over (labarious task)

do u think the spare drive will need to be formatted on the wii u beforehand?

So clone zilla did not even detect the partition on the wii u drive

The source and destination drive came up but when trying to clone the data it came up with an error saying it could not read the drive etc

When trying to copy partition nothing got picked up on the source drive either. Perhaps using 2x usb docks will be best here but it’ll take aages

I'm curious if the CloneZilla method will work. All the save games are on the Wii U HDD if you store your games on there also. So if the HDD breaks you also loose your saves if you didn't make a separate backup. I'm still searching for an easy backup solution, maybe this is it but another user in 2016 already said:

"You can clone a drive all you want but the WiiU uses a proprietary eCON encryption on the drive. It takes the drives firmware, serial, partition data AND usb interface into account. It is very similar to how feature film studios lock their USB drives. Even if you take the drive out of the enclosure, it will NOT be read in anything other then that specific USB enclosure AND the original mobo of the PC it was locked too."

And another user from the same topic:

"So here is one fun fact: Wii U lets you connect two drives at the same time in settings menu, you can take backup data to another drive you format to wii U format, and you can copy the content over to that drive from your main one. You can also periodically then update the save data or whatever to the other drive. Wii U will not like it if you enter home menu with two drives tho."

For that last problem you can:
  • Shut down your WiiU
  • Plug in new HDD and format it with the WiiU
  • THEN plug in the original drive
  • WiiU will kick you to the drive storage menu
  • Copy ALL from the source to the new drive.

But with usb2.0 that will take aages.

Interesting, the encryption is salted with like everything ...? I should test using a different enclosure (during the next weekend)

well coming back on here after today's trial and failure.

I got a spare 1tb drive and thought I'd try the copy method....

1. Connected spare 1tb drive to the wii u on its own and formatted it.
2. connected both the spare and the other 1tb drive together to the console.

then it would complain of a software error and I could do nothing but restart and the same error occured
basically the wii u did not like 2 x HDD's connected at the same time.

so for now all I did was just backup all of the games but if this HDD crashes I will need to invidivually go back and copy all of the games to SD and then to the new HDD
let's hope it lasts a while!

I switched the enclosure of my Wii U formatted HDD. It is still read by the Wii U (but both enclosures are from the same producer and same model type tough)
