Comments on: How I saved my corrupted Time Machine sparsebundle image…

Try “hdiutil … -verbose …” next time. It’s much more interesting to watch then.
I had to repeat the command and attempt to mount the volume a couple of times until it was successfully repaired.

kernel HFS: Runtime corruption detected on , fsck will be forced on next mount.

this looks pretty bad… seems more like a disk error than anything else.
And, yes, I agree a backup solution should be reliable. Although TM is more like a “failsafe” than a real backup… better than nothing though. Consider than the vast majority of TM users would never do a backup if it wasn’t for TM.

Certainly some mac wizardry done in this discussion to correct TM, but I second the plea for a TM backup that just works. Im running 10.5.4 now and a week or so ago failed. Here’s the latest log:

Before I start copying/repairing hundreds of Gigs worth of data or punching in terminal commands (deep water for me), would somebody lend a hand? Cheers!

Noted, but this is weird… have you had any look in the SYSTEM log using Console.app? To see if the backup process reports a problem?

*** NOTE ON TIME MACHINE AND ANTI-VIRUS SOFTWARE ***

Time Machine does NOT work well with some of the anti-virus software out there. Case in point is iAntiVirus for Mac.

When that software is running, even if you disable the real-time checking, Time Machine will get stuck on “Preparing…”. In my case, TIme Machine was backing up over the LAN. I have not tested it with an external drive connected directly to the MacBook via USB or Firewire

Nope, sorry but I have no idea… Your log seems to say exactly what a Time Machine log should say when it cannot use the “fast track” list of changed files, and it need to recheck everything… so it SHOULD work, even if it would take a bit of time to recheck all your files before doing the backup. On my system with about 200+GB of files, it takes around 30′ to 1hr to do a “deep traversal”…

That’s great it worked for you.

I’ve been working on a solution for my (similar) issue for about 2 months, and I followed your suggestions, and I still get an error message “Back Up Failed” from Time Machine.

I can mount the image. I can browse the image, but I just can’t back up to it.

These are the last few lines of my system.log:

Aug 23 21:08:39 Macintosh /System/Library/CoreServices/backupd[9289]: Disk image /Volumes/Mathew Maher’s Time Capsule-1/Mathew Maher’s Computer_0016cba494e1.sparsebundle mounted at: /Volumes/Backup of Mathew Maher’s Computer

Aug 23 21:09:10 Macintosh /System/Library/CoreServices/backupd[9289]: Node requires deep traversal:/ reason:kFSEDBEventFlagMustScanSubDirs|kFSEDBEventFlagReasonEventDBUntrustable|

Any ideas?

Well, the thing is I did what you tried, but over Ethernet… what you do is you connect to the TC, then copy over the whole .sparsebundle, without mounting it… it should not take as long as the copy dialog says… although I would not recommend doing it over Airport.
Good luck.

I am currently working through this issue. I have a 250 gb sparse image that I am trying to repair with Disk Warrior.
Question though, how did you copy the image to a USB drive from the TC? I attached a USB drive and attempted to do this but the progress meter sated it would take over 225 hours to copy.

Whoa, thanks! After running the first command I was able to mount my sparse bundle (containing a Journler database of all of the journals I’ve written since I was 10 years old, and of which there are currently no backups anywhere) and repair it with Disk Utility. Thanks!
