HELP! Error Code 512. TM not backing up at all.

Hi.

I know y'all are such nice peeps 😉 and will help me.

So I have a MacBook which has a Time machine configured to back up to a NAS device that is attached to my home router. (D-link DNS-323 NAS device. Raid 1. 2x1.5TB)
So I have noticed that my Macbook was getting slower while backup is happening, and hence I looked up ways to back up once every 24hrs. And some bloke here have said to edit your com.apple.backupd-auto.plist file

<key>StartInterval</key>
<integer>3600</integer>
Change the 3600 number to some other time interval in seconds, and you'll have changed Time
Machine's backup interval.

Which I did. But ever since, it didn't back up. I made sure Time Machine wasn't backing up when the changes to the file were made.
I even changed the file back to the original code as above.
(Although I suspect the above instructions have little to do with Time Machine problem I have now.)

It does not back up at all!

Now, when I click 'Backup Now!', I get this error

*Time Machine could not Back up Now.*
*Error code 512 (fffuuuuu!)*

Can y'all please help me? What should I do? 😟

So I went to Console and printed my system.log
Here it is what I see when Backup now is being clicked.

TM will not backup to a NAS connected to any router. Even an Apple Extreme Base Station only supports a directly connected hard drive, and that configuration is not Apple supported.

To do what you're doing requires a hack, and such hacks are not supported by Apple. So I suspect the problem you are having may be related to one or both of these facts.

From your console log it's apparent that TM is trying copy the sparsebundle disc image to your local volume and not succeeding. But I don't notice anything particular to suggest why. Error 512 is not a standard Mac error code or a TM error code, but it may be from your NAS.

Kappy: TM has been backing up to my NAS device this way for the last one year. There is a simple hack to let TM back to any NAS device. There are many websites which give you instructions how to do this. Here is a link to setup TimeMachine to back up to Unsupported Volumes. http://www.engadget.com/2007/11/10/how-to-enable-time-machine-on-unsupported-vol umes/

Yes, I know but these hacks are not supported. TM is not designed to work properly in this fashion. If the hacks fail in some way Apple provides no support and you are on your own to resolve the problem with the NAS and/or router manufacturers. That is the apparent situation you are in based on what I was able to find about the error and strange appearance of the log entries related to the naming of your sparsebundle which is not correct. This may be the reason for your problem.

I am fully aware of the hacks and probably have been for much longer than you. So, as you will find recommended in the link I sent you which describes a similar problem to yours that the error is probably caused by your NAS not by OS X nor TM.

As Kappy says, Time Machine doesn't work well, if at all, with many NAS devices. See the pink box in #2 of [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

So I have noticed that my Macbook was getting slower while backup is happening, and hence I looked up ways to back up once every 24hrs. And some bloke here have said to edit your com.apple.backupd-auto.plist file

That's treating the symptom, not the disease, and is not recommended.

Which I did. But ever since, it didn't back up.

Great. You may have corrupted your installation of OSX.

*Time Machine could not Back up Now.*
*Error code 512 (fffuuuuu!)*

Those are not Time Machine messages; they appear to be coming from your NAS.

*Dec 17 18:35:48 Stephen-Phelans-MacBook-Pro com.apple.backupd[420]:* Backup verification failed for image /Volumes/Volume 1-1/Stephen-Phelans-MacBook-Pro_58b035f0298f_2010-12-06-112926_2010-12-06-120204 _2010-12-06-131523_2010-12-06-141523_2010-12-06-151525_2010-12-06-162710_2010-12 -06-183823_2010-12-06-202535_2010-12-08-084358_2010-12-08-0859512010-12-08-095951.sparsebundle!

Your backups and/or installation of OSX and/or relationship with your NAS are corrupted (even the name of the sparse bundle is corrupted, which we've also seen with NAS backups). Time Machine found them corrupted, and can't even delete them to start over.

Get an external HD, format it (per #5 in the FAQ), do a "full reset" of Time Machine per #A4 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum), and select it as your backup destination and try a backup.

If that doesn't work, erase the external disk and use the Restore tab of Disk Utility, in your Applications/Utilities folder, or CarbonCopyCloner or SuperDuper to make a "bootable clone" of your internal HD on it. [CarbonCopyCloner|http://www.bombich.com> is donationware; [SuperDuper|http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html] has a free version that will work for this. Start up from the clone and make sure it works.

Restart from your internal HD. Delete the plist you edited, and reinstall OSX from your Snow Leopard Install disk. When your Mac restarts, download and install the 10.6.5 "combo" update. Info and download available at: http://support.apple.com/kb/DL1324 Be sure to do a +Repair Permissions+ via Disk Utility (in your Applications/Utilities folder) afterwards.
