Time Machine fails to backup - no access to a specific file?

[yegon]

The following error message appears when I attempt backup using TM;

"You do not have appropriate access privileges to save file “.0019e33d49f6” in folder “Time Machine Backups”.To view or change access privileges, select the item in Finder and choose File > Get Info."

Spotlight can't locate this file, I've ran disk utility to verify and repair the internal drive, verified the external, no problems on both counts. I even tried allowing read & write privileges temporarily to everyone on both drives, but no luck.

Any suggestions?

edit: I notice under sharing and permissions on my root\user\matt (that's me) directory it has 3 users, Matt, Unknown and everyone. I can't change Unknown away from read only, is that normal?

Anyone?

I'm really having no luck finding a solution to this. I could just treat the external as a new drive and re-backup from afresh (I've got another backup stored elsewhere) but over 300gb will take aaaaaages :-(

I used Invisibility Toggler to make the offending file visible on the backup drive, deleted the fie, and then retoggled to make the files invisible again.

It now seems to back up fine.

You could probably get info on the file and change permissions instead of deleting it, but deleting seems to work.

Cheers, I may try that if it happens again.

In the end, I just erased the disk and created a fresh backup from scratch and left it going overnight.

In my case I'm switching back to an older Time Machine backup so I suspect this is done deliberately otherwise the FSEvents aren't in sync with the older backup so a lot will be missed. I think Apple wants you to backup from scratch when this event happens.

Ran into this error today....found a fix here

I ran into this same problem a couple of days ago as well.

I just did a chmod 777 on the file and then TM started working.

maybe better to chmod....I used my post above (which is perhaps too aggressive, and had some hanging issues...did a repair disk after starting off the install DVD...cleared it up...
