TM is not backing up and I cannot get to previously backed yo stuff (it worked before). I use TC to back up. The 'connecting to back up volume' stays on forever. When I delve deeper it says "disk image failed to mount"
Although it is S-L-O-W, you can back up the good sparsebundle images onto a external hard drive via the USB port (there is an archive command within AirPort Utility); or connect a computer via ethernet to the Time Capsule, connect a firewire or USB drive to the computer, connect to the Time Capsule in Finder, and copy the files using Finder.
Once you have copies of the good images, you can delete everything and restore the TC to factory condition, redo all the settings, and copy the good files back; then tell Time Machine to create new backups of the Macbook.
Altnernatively, just trash the bad disk image and tell MacBook's Time Machine to create a new backup. As others have said, its a huge bummer that you have to toss out your entire collection of backups of that computer due to a TC error.
Per the assistance of another user in another thread, I was able to delete my .sparsebundle while leaving the other computer's sparsebundle in tact. If you right-click (control-click) on the offending .sparsebundle and select "show package contents", you should be able to delete the contents within the "bands" folder by holding option while dragging them to the trash. After that, I was able to delete the empty .sparsebundle.
Now, I can spend the evening recreating my spontaneously combusting failsafe archive 😝
Open Airport Utility and select the TC. Click on the "manual setup' button. Up in the menu, select Basestation > Upload Firmware. Here you can hit the button 'downgrade'
Again, it totally worked for me as well as for others! Good luck, let me know if you were successful!
I had this problem with my wife's MacBook's TM backup.
Tried repairing in Disk Utility. Didn't work because Disk Utility couldn't repair it.
Tried everything suggested above but nothing worked - even downgrading firmware. The sparsebundle was proper broken.
So, deleted it and started TM afresh on the machine.
That was yesterday.
Today - the problem is back. Same problem with the sparsebundle.
So, what was my wife doing? Well, she takes her laptop back and forth to work and just closes the lid and goes. She doesn't pay any attention to what the machine is doing. Even if it is performing a backup for her.
It looks like she closed the lid on both occasions during a TM backup.
I would have thought that if this action is so catastrophic, Apple would know about it and they would either prevent the machine going to sleep and make it beep LOUDLY and present a message on-screen OR they would incorporate some form of fall-back in the TC to cope with a wireless client suddenly disappearing off the map during a backup.
Another one here. yesterday in fact....tried all optiosn like disk utility but no go. Had to erase this disk and start from scratch again....what a pain!
And yet one more, I have the TC for 2 months now. The back up worked perfect for about 5 weeks. Then the back up failed and I endend up (after trying everything mentioned here) deleting the corrupted file. The back up (58 GB) "only" takes the TC about 36 hours to make(Apple wants to make sure that the back up is good I gues) it worked for 2 weeks and yet again a corrupted file. I contacted appple support and they sugested I format the TC slowly. Another 36 hours gone. I'm on my 3rd complete virgin back up now!
I make a back up to make sure my files are save. Now I don't even know if the back up will work when I need it to so I worry about that aswell beside waiting for yet another corrupt file! Why does Appple pretend that there is nothing wrong with the TC? The reason I bought a TC is for the back up, it is the most importand feature of the TC.
Reading this post I see the problem is mostly with Mac books, I own a Mac book pro.
Is there anyone with a solution beside deleting the file?
I have just downgraded to to firmware 7.3. I hope it will solve the issue. I let you know what happens, but don't expect a answer very soon because the back up takes forever...
Please, anyone else who has downgraded to 7.3 please report whether your sparsebundle images are still corrupted, as there have been mixed results. Some of the published writers said that 7.3.1 really helped with the stability of the TC as an airport base station, so downgrading comes with some opportunity cost.
