Time Machine error: backup disk image could not be created

Hi,
I too have a Western Digital NAS Drive and have used the terminal command to view the drive and I'm also receiving the "Backup Disk Image could not be created" error.
Please let me know if you have found a solution or had any success.
Thanks

The advice at this URL fixed it for me:

Basically Time Machine seems to be having trouble creating and/or mounting the sparseimage properly. The advice here is to create your sparseimage locally and then copy it to the TM drive or network drive you intend to use manually. It fixed this problem for me after all of the above advice did not.

Thank you SO SO much for this link! It worked perfectly, and has saved my sanity!

Hey,
I have found any help yet. I really want to get it to work. If you find any solutions, please let me know.
Thanks

Syd & K! The suggestion worked great. Adding a Name under Sys Pref / Sharing sorted it. What an annoying bug.

Hurry up Mac and release an update to fix this, please! So that all the new newbies that don't get to forums don't have to go through the same heartache!

After multiple tries with the ReadyNAS info, along with the same teqnuqie from other sites, I still couldn't get the .sparsebundle to copy onto the HDD. No matter what kind of copy command I did in terminal, the file would not duplicate over to my external. I was going insane trying tons of difficult ways to do it.

Just to let anyone else know who may have the same problem as me.

Just find the .sparsebundle in your /User/ directory and drag and drop it onto your HDD. As soon as I did it TM started working flawlessly. And yes, I about fell over when I found out that was all that needed to be done.

thanks - this helped me out!

you're a genius. thank you!!!!

I have set a name in sharing and still get this error when I try to use Time Machine. Any other suggestions?

Thank you very much. Your solution worked for me too.

Thanks Syd and all.

I had (a) "Backup volume is read only" and then (b) "The backup disk image could not be created" errors.

(a) was resolved by:
1. go to TM preferences and select no disk
2. \rm -rf xxx where xxx is the sparse bundle on the TC.
3. reboot
(b)
use method Syd said above to give the machine a sharing name

Reboot. Select TC as the target backup volume for TM. Backup now works again.

No thanks to Apple for creating this nightmare for many users, which appears to have been percolating for over a year.

Syd, thanks a lot.

Thank you syd-music!!! That fix worked perfectly. Much appreciated.

Thanks, that solved my issue. All I had to do was give the computer a name, and Time Machine worked fine.

For me, I deleted the list of "omit these folders" and started again, omitting a bunch of stuff just to see what was needed to get it working again. It's working fine now, so there must have been something messed up about the omit-these folders.
