Time Machine Verification Issue

A window just popped up saying: "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you." It goes on to say, "Click Start New Backup to create a new backup. This will remove your existing backup history. This could take several hours."

What is this??? Does this indeed mean that I will lose ALL my backups over the past year? When I selected my Time Capsule icon and chose "Get Info", the "Sparse Disk Image Bundle" says that it is 317 GB. Since my Time Capsule is 500 GB, I assume this is not a full disk issue.

If I click on the "Start New Backup" button, will that mean my Time Capsule will be totally erased, and I will start over with a full 500 GB drive?

One clue: This afternoon I did perform an update from the "Software Update" menu item, and I installed OSX 10.6.4. Could this upgrade be the culprit? If so, have there been any other such reports of a Time Machine issue with the upgrade?

MacBook Pro, Mac OS X (10.6.4), 2.53 GHz Intel Core 2 Duo, 320 HD, 4 GB RAM

My very strong opinion here, but Time Machine is crud and a total fail for me.

I had two failed attempts at a complete restore of my system and data in OS X 10.5 Leopard with Time machine when I really, REALLY needed to have a good system restore and then gave Time Machine the benefit of the doubt and tried to use it one more time in OS X 10.6 Snow Leopard where it failed an incremental restore and much later time, another full restore.

Three strikes and I am done with that foolishness.

I am soooo done with OS X Time Machine. It is NOT a reliable and consistent backup solution, AT ALL!

Bootable data clones using cloning software is by far the best and most reliable way to create a good and completely viable backup.

AND having multiple drives with bootable systems and data clones mean redundancy against eventual drive failure and the possibility of a corrupt cloned backup.

In the 12 plus years I have been using data cloning software for backups, I have never had a backup go bad or corrupt or have an incompatibility with different installed OS X versions.

So I have a problem with .sparsebundle

iMac-Sebastian:~ root# hdiutil attach -nomount -noverify -noautofsck /Volumes/My\ Passport/TEMP/iMac\ \(Sebastian\).sparsebundle

/dev/disk6 GUID_partition_scheme

/dev/disk6s1 EFI

/dev/disk6s2 Apple_HFS

iMac-Sebastian:~ root# hdiutil attach -nomount -noverify -noautofsck /Volumes/My\ Passport/TEMP/bad.sparsebundle

/dev/disk5

iMac-Sebastian:~ root#

As you can see IMAC.sparsebundle works well and I can mount it. On the other hand BAD.sparsebundle shows only ONE disk. I HAVE to pull files from the BAD.sparsebundle. If you can somehow work with the files in the directory BANDS? What can I do to FORCE bad.sparsebundle to action?

Hi Alex:

Were you able to fix your problem? I am also stuck here:

/dev/rdisk8s2: fsck_hfs started at Tue Nov 25 19:58:50 2014

/dev/rdisk8s2: /dev/rdisk8s2: ** /dev/rdisk8s2 (NO WRITE)

/dev/rdisk8s2: Executing fsck_hfs (version hfs-285).

QUICKCHECK ONLY; FILESYSTEM CLEAN

/dev/rdisk8s2: fsck_hfs completed at Tue Nov 25 19:58:50 2014

I've been dealing with this for a couple of months now and have not been succesful....

Any help will be appreciated; Sguzman99

Although, this thread is some years old, I am stuck with the same issue of a broken sparse bundle giving me only one disk:

hdiutil attach -nomount -noverify -noautofsck /Volumes/ZweiTera/MacBookS_685B359B70A92.sparsebundle

/dev/disk3

Any news on this how to solve it somehow? I really need this backup! Thanks
