What does "sparsebundle could not be accessed (error -1)" mean?

My Time Capsule has ended backups with this error message lately. I cannot find anything in Apple Support that addresses this error or how to fix it. Please advise.

There are a number of different things that can cause this error.
See # C17 in Time Machine --- Troubleshooting for specifics.

The backup disk image "....sparsebundle" could not be accessed (error -1)

Hi,
I just started using Time Machine with Time Capsule to backup my computers. It seems to work fine with my MacBook but I have not been able to backup my iMac. They are both on the same network. As far as I can tell, the settings are the same on both machines. When I do the initial backup on the iMac, I get this error message:
The backup disk image “/Volumes/time capsule/bill’s iMac_0026080c21e8.sparsebundle” could not be accessed (error -1).
Any ideas about what I am doing wrong would be appreciated.
Thanks.

I had the same problem and it appears that the advice 'rename your computer's name in system prefs -> sharing to something less than 25 chars and no special chars / no spaces did the trick ...
actually .. it did not .. it was trying to create a new sparsebundle ... and it came back with the same error ... the TC has been used by a different mac for 2.5 years by now, with no issue .. i should be able to back up a second mac there, right ?

"iMac.sparsebundle" could not be accessed (error(null))

My time capsule backups of my iMac to the time capsule has not worked since Nov 11. I think I may have turned it off at that time because the frequent updates were slowing down my iMac. Since then I've upgraded the RAM. When I turned on the Time Capsule back-ups, however, I keep getting an error message:
"The backup disk image "/Volumes/My Time Capsule/My iMac.sparsebundle" could not be accessed (error(null)).
I don't have a disk for my current Operating system, which is OS X 10.9.2. I have downloaded my last several upgrades thru the Apple Store.
I have gone thru some of the simple steps rebooting everything. I started the Terminal and gave the commands that Linc Davis suggested in Oct 2013, article with same message, but (error(-1)). I got the lines below:
I really don't know what to do during a safe mode restart.
Can anybody help me to get my Time machine working again?
Thanks for any help,

First, if this is your only backup, you must make another full backup to a locally-attached external hard drive. One backup is never enough to be safe, and backing up over a network is less reliable than backing up locally. Then try each of the following steps that you haven't already taken.
1. Restart the backup device. You can do that by disconnecting and reconnecting the power cord.
2. Hold down the option key and select Verify Backups from the TM menu in the menu bar (not the Dock icon.) This operation may take several hours. If the menu-bar icon (a clock that runs backwards) isn't showing, check Show Time Machine in menu bar in the preferences.
3. Erase the backup device. With a Time Capsule, you do that from within the AirPort Utility application; see its built-in help for details. All backups will be lost, so don't do this until you've backed up to another device. After erasing, select the TC again as a backup destination in the TM preference pane. The first backup should be made over a wired connection, if possible.

Since upgrading to Lion, my time machine backups are failing - error message: The backup disk image "/Volumes/Jackie Scanlon's Time Caps/Jacqueline Drabczynska's MacBook.sparsebundle" could not be accessed (error -1). Any ideas?

Since upgrading my Macbook to Lion, the time machine backups are failing - error message: "The backup disk image “/Volumes/Jackie Scanlon's Time Caps/Jacqueline Drabczynska’s MacBook.sparsebundle” could not be accessed (error -1)." I have rebooted the TIme Capsule and it worked OK, but don't want to do that every time. Any suggestions? Thanks

Any new info on this?
I had the exact same problem and went crazy and spent a hecka lot of time trying to deal with my brand new 2TB Time Capsule and almost brand new MacBook Pro. Then I thought I fixed it...and I tried SO MANY things, I don't really know what did it...except taking out any apostrophe's in names of stuff that Apple puts in there...BUT...now it's back.
Grrr...

Error: the backup disk image "/Volumes/Data/David's MacBook Air.sparsebundle" could not be accessed (error -1).

okay all of a sudden my TC 2 TB is not backing up.

macbook air late 2011 model
error: he backup disk image “/Volumes/Data/David’s MacBook Air.sparsebundle” could not be accessed (error -1).
i don't see a sparse bundle file by name per se anywhere.
Also what is new: as soon as time machine auto kicks off or I manual kick it of, it opens a new window which contains one folder (my backup fies from other days) the files are "there", but I cannot successfully back up now?

New 2 tb time capsule with air extreme built in. I can surf the net wirelessly through this device. And it had been backing up all along then a few days ago it stopped and reported that error.

/Volumes/Data/my computer.sparsebundle could not be accessed (error-1)

Since upgrading to Lion I keep getting "Volumes/Data/my computer name.sparsebundle" could not be accessed (error -1) message. I will go into the airport utility, delete the backup and start over. It will work ok for a couple weeks and the message comes back. I have the most recent firmware update in the timecapsule. Is there an issue with my timecapsule itself, or do I need to upgrade to a larger one. My current 1 is 1T, my mac's hard drive is roughly 75% full.

I checked the pondini fixes and ended up doing the following - in case this could help someone else with OSX Lion and Time Capsule... http://pondini.org/TM/Troubleshooting.html
First, I downloaded and used Airport Utility 5.6 instead of 6.1 - BTW, I had to attempt download and installation THREE times before the program actually installed. Be persistant.
Pondini #5: It's possible some names (of all things!) may be a problem. See item C9. I had to re-name my Mac, Time Capsule, network, etc... to remove all apostrophes and spaces.
Pondini #7: If you have WD SmartWare installed on Lion, it's not compatible, per RoaringApps, and there are reports it can cause this problem as well. Use Western Digital's uninstaller, or delete the app from /Applications and the files com.wdc.WDDMservice.plist and com.wdc.WDSmartWareServer.plist from /Library/LaunchDaemons. There may also be a file in Library/Application Support.
I then had to shut down computer, unplug Time Capsule, unplug modem; plug everything in again, then reboot computer; then had to go to Apple- System Preferences- Network- and reselect my Time Capsule to connect to WiFi again.
Then opened Time Machine preferences again and attempted back up - it worked!

Mac.sparsebundle" could not be accessed (error -1).

I recently installed my time capsule to back up 2 imacs and 2 macbook pros it was running fine until i restarted my imac and then i get a message.(Mac.sparsebundle” could not be accessed (error -1).) and I would have to reset my time capsule and then go into my air port utility and set it up all over again I am getting really sick of having to redo my time capsule every time . does anyone have any solutions??

I'm having the exact same problem. As my iTunes library was getting too large, I needed to transfer these files to another hardrive. Since doing this, I'm getting the following error message. The backup disk image “/Volumes/Data/MacBook.sparsebundle” could not be accessed (error -1). I've also recently updated the firmware to my Time Capsule and now having problems with accessing my wi-fi connection. My fix is having to reset my TC, then setup via AirPort to get the connection. Has anyone else in the community experienced this and know a solution? Thanks : )

The backup disk image "/Volumes/Data/Macintosh.sparsebundle" could not be accessed (error (null))

I keep getting "The backup disk image "/Volumes/Data/Macintosh.sparsebundle" could not be accessed (error (null)).
I have updated the firmware on the Time Capsule and unplugged and replugged it in after waiting more than 10 seconds.
I cannot access the sparsebundle to repair from the Disk Utility.
Does anyone have any other suggestions?

It sounds like you have already tried some of pondini's suggestions..
But C17 is the main one, even if the error is a different number..
http://pondini.org/TM/Troubleshooting.html
Mavericks in particular is having issues with the TC..
So I strongly recommend a full factory reset of the TC.
Make sure all names are short, no spaces and pure alphanumeric. See C9 for more info.
Because Mavericks now uses SMB by default for network protocol, it is worthwhile mounting the TC manually using AFP.
In finder use the top menu, Go, Connect to Server.
Type in as follows,
AFP://TCname
Replace TCname with your actual TC name..
If the computer fails to find the TC, try again using the full domain name.
AFP://TCname.local is the standard one. The TC opts for local although you now have no place to set it in the airport utility.
If you still have trouble tell me.
Once the computer locates the network resources, it will ask for a password, public by default. Type in your password if you changed it or public. And store it in the keychain.
Now reset TM.. see A4.
And point the TM to the TC again which you have mounted.
See if that helps.

How to solve: The backup disk image "/Volumes/Data/IP's Mac mini.sparsebundle" could not be accessed (error -1).

Hi,
Please help!
I set up my time capsule yesterday, and it worked perfectly initially. However, after I used the same time capsule HDD as network file sharing with my MacBook Pro and two other PCs, than the hourly backup failed and gave the following error message.
The backup disk image “/Volumes/Data/IP’s Mac mini.sparsebundle” could not be accessed (error -1).
Please help telling me what to do to restore the backup function.
ipmt

First, restart the Time Capsule by disconnecting the power adapter and reconnecting it. If other devices on the network can see it, you can skip this step.
From the menu bar, select
 ▹ System Preferences ▹ Network
Click the lock icon in the lower left corner of the window and authenticate to unlock the settings, if necessary. Click the Advanced button, then select the TCP/IP tab in the sheet that drops down. Click Renew DHCP lease.
Try again to back up.
If you still can't, open the Time Machine preference pane and delete the TC from the list of backup destinations. You may have to unlock the settings by clicking the lock icon in order to do this. Then add it back.

Time Machine could not complete the backup.

Could anyone...PLEASE....tell me how to fix this. And what's the difference between error 119 and error -1
Thanks a million

Hi
I had the same problem.
Then, because the problem happened each time I restarted my Imac, I tried to check the apps starting at login.
I went to system preferences - users - login items and I looked at some "apps starting automatically at login",
In my case I deleted "WD Macintosh + Turbo drivers" (an old version incompatible with 10.7.2) and I resolved the problem.
I hope I've been helpuf
