So recently i tired time machine with my brand new time capsule and it didn't work... I get 2 different error messages, If i start clean in the time machine i get errors 20,60 but if i try again i get errors 17,20 or the text below:

It says The backup disk image "/Volumes/Data-1/WyattsMac.sparsebundle" could not be created (error (null))

I have tried setting a local name and restaring everything but that wasn't it so how can i fix this?

Launch the Keychain Access application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Keychain Access in the page that opens.

Select the System keychain in the list of keychains in the sidebar of the window. If you don't see the list, click the down-arrow icon below the sidebar.

Then select Passwords in the Category list at lower left. Click the Kind heading in the list of keychain items to arrange it by Kind.

Locate the AirPort Disk Password with the name of your backup destination. Double-click the item and check the box marked Show Password in the inspector window that opens. You'll be prompted for the administrator login password. Make a note of the AirPort password, then close the inspector window and delete the item.

Also delete any other AirPort DIsk Password items for that same destination, if it had a different name in the past.

Quit Keychain Access and try again to back up.

Hi Link, I just wanted to add my thank you to you as well. I have had endless problems after upgrading to Mavericks. I googled "sparsebundle could not be accessed error (null)" and came across this question and your resolution. Your answer worked in my case as well. Not sure why I had SEVEN! different password entries (all containing the identical password) in Keychain, but I deleted them all and now I can finally complete TimeCapsule backups. Link, you have hopefully helped discover solutions to other problems I am having.


Could you possibly explain the "Why?" Why would Keychain Access have asked to store this same password so many times in the past? I am finding multiple password entries for the same server, whether it's Mail, or my other computers, or com.apple.facetime, but they all contain the same password. I can see where some serious Keychain housekeeping will hopefully help my many issues.
