Time Machine backup to Windows Share Now Failing Verify

Hi Everyone - I have searched everywhere and can't find any help.

This is my situation. I have my TM backup to an SMB windows share and its been working fine for months. Two things changed recently: a) I installed Windows 7 on my windows box and b) I installed that TM update that provides greater reliability. Backups worked fine for weeks after both of these changes, but just this week backups failed and TM wanted to create a new backup. I tried to recreate a new backup, but it keeps failing with errors below. When I try to run a verify disk on the sparsebundle (with disk util) I always get errors, but of course, I can not fix the errors when the sparsebundle is on an SMB. I am currently running a chkdsk on the windows drive, but I don't think its damaged.

Anyone encounter this? I essentially can not use TM right now. Could the TM update and/or windows 7 upgrade be a contributor? Any help is much appreciated.

Is that a "supported" destination? According to this Apple article: Disks that can be used with Time Machine

*+If your backup disk is on a network, the network server must use Apple File Protocol (AFP) file sharing, and both your computer, and the networked backup disk, should have Mac OS X 10.5.6 or later.*+

It appears to have finished the actual backup (two passes).

8/18/10 11:39:51 PM kernel hfs: node=4844 fileID=4 volume=Backup of MYMBP device=/dev/disk3s2
8/18/10 11:39:51 PM kernel hfs: Runtime corruption detected on Backup of MYMBP, fsck will be forced on next mount.
8/18/10 11:39:51 PM kernel hfs: cat_delete() failed to delete thread record on volume Backup of MYMBP


Then has a problem; apparently unable to delete the thread record, although listed 3rd, seems to be where it choked.

And can't fix it on remount.

Thanks. No its not supported, but this has worked for me in the past


That's the problem with doing something unsupported -- an OSX update may break it.

With all the reliability talk about TC's


That was mostly about the early models, with a power supply problem, and Apple is replacing them: http://support.apple.com/kb/TS3351 The later ones seem to be much more reliable.

And if you purchase AppleCare for a Mac within 2 years of buying a TC, the TC is covered, too.

and not to mention the extra cost


Yeah, they are pricey. But if you need a good wireless router anyway, it's not too bad.

I don't want to have to plug in a USB either.


If you have a desktop Mac, you can back up to a shared drive on it.

Thanks for your replies. I am very suspicious that the TM update did break this method. Good to know on the TC + Applecare thing, but $300 for a backup station when I already have a router is hard to justify. I have a custom router with a custom firmware as well and I need that flexibility for my home network.

I may just have to go to plugging in a USB drive for this. I don't have a desktop Mac as this laptop is my first mac.

Thanks again

That may very well be. We've seen no details on just what it's doing, but it seems to find problems that Disk Utility couldn't find, much less fix. It's quite extraordinary.

Yup.

Obviously, you need an iMac! 😉
