Hey Guys,

I am having a time machine backup problem here, for at least 3 months. I tried the TimeMachine Troubleshooting tips, but none success. So I am asking help at here.

When I backup using time machine, it always have error (-36), the following is the log for my latest backup

*+Starting standard backup+*
*+Backing up to: /Volumes/TimeMachine/Backups.backupdb+*
*+Ownership is disabled on the backup destination volume. Enabling.+*
*+Backup content size: 101.5 GB excluded items size: 4.6 GB for volume Snow Leopard+*
*+No pre-backup thinning needed: 116.37 GB requested (including padding), 148.45 GB available+*
*+Waiting for index to be ready (101)+*
*+Error: (-36) SrcErr:YES Copying / to (null)+*
*+Copied 1 files (26.5 MB) from volume Snow Leopard.+*
*+Starting post-backup thinning+*
*+No post-back up thinning needed: no expired backups exist+*
*+Backup completed successfully.+*

In the log, it says "Backup completed successfully", but the problem is I need to backup about 100GB stuff, but only 26.5 MB was backup.

I tried verify disk, reset time machine, erase backup disk. But this problem is still there.

Hope some one could help me! Thanks!

    Hi, and welcome to the forums.

    This is a strange one.

    Backup content size: 101.5 GB excluded items size: 4.6 GB for volume Snow Leopard


    It does see that it needs to do a large backup.

    Error: (-36) SrcErr:YES Copying / to (null)
    Copied 1 files (26.5 MB) from volume Snow Leopard.


    I'm assuming that +Snow Leopard+ is the name of your internal HD, correct? And that's the one you ran a +*Verify Disk+* on?

    From a Finder window, select +Go > Go to Folder+ and type a single forward slash into the prompt.

    That should produce a list of all the volumes connected to your Mac (plus the special "Network" entry). See if anything else is listed there.

    Eject and disconnect anything you can, do a Restart just to be sure, and try again.

    Hi there,

    It seems I am having a similar problem. I started having this problem last September, were the backup failed for more than 2 weeks without any single error message. By that time, I found some bad sectors in the disk (Using SMART utillity), so I have bought a new disk and have performed a fresh installation. I have only copied the /User stuff from the old disk and did not include any system file. Anyway, after a few backups I found the same problem. The log always reports an error while copying the root directory ("/"). After rebooting, the backup finishes without any problem.

    I use OpenAFS in my system, which creates an additional volume, but I always excluded the "/afs" directory from the backup. Despite that, after reading Pondini suggestions, I suspect It has something to do with the AFS volume.

    Here follows the Backup.log output during last failure:

    Hi,

    I cannot take TM backups any more. Latest successful was 2010-4-2 about 19:20 local time (Finland).

    What is changed in my iMac G5: I installed the latest leopard update 10.5.8. I started to use iMovie, so the amount of backup increased rather much. The first error occur 2010-4-2-2105. I tried to delete the inProgress file without success, Then I moved Backup-file to another name. I also reduced the amount of backup and adjusted energy saving options. I also checked my disks with disk tool and they were OK.

    I enclose the latest log:

    Not a good idea. Sometimes you can do that without problems, other times it will corrupt your backups.

    Then I moved Backup-file to another name


    Do you mean you renamed the sparse bundle containing your backups? Or the Backups.backupdb folder inside it? Or copied it somewhere?

    c :ERROR:-128, copy / to (null)


    That's the same error as the two previous posters. I've never seen it before.

    Please do as I requested of the first poster:

    *From a Finder window, select Go > Go to Folder and type a single forward slash into the prompt.*

    *That should produce a list of all the volumes connected to your Mac (plus the special "Network" entry). See if anything else is listed there.*

    *Eject and disconnect anything you can, do a Restart just to be sure, and try again.*

    Let us know what you find.

    Hi,

    I was not able to delete the package and I restored it to the original place.

    I used mv command to Backups.backupdb - > Bup.backupdb so that I could start the TM backup from scratch.

    Your last check: I saw the internal hard disk, and 2 external drives and the network. Looks normal to me.

    When I tried the backup last time, the display was locked and I had to type psw. And yet I tried to stop the sleep using System Preference settings: start screen saver never and energy saver put the computer to sleep when it is inactive "never". And despite of that the screen was locked, odd.

    If you mean the "in.Progress" file, your backups are corrupted. Delete them and let TIme Machine start over.

    And the drives were all aliases, right? If not, post back.

    It does sound like your backups are hopelessly corrupted. Erase the TC (or delete the sparse bundle) and start over.

    I don't think my backups starting 2009-06-02 are corrupted totally. I only cannot take more backups for some reason starting 2010-4-2.

    In column Kind there reads Volume, not alias.

    I think that the backup disk disconnects it for some reason = > null device.

    A new backup may fail because the backups are corrupted. Time Machine backups are not separate items; they're all interdependent, with multiple "hard links."

    In column Kind there reads Volume, not alias.


    That's a problem. What's the name of the volume? Open it with the Finder, and see what's in it.
  • Juha K Savola Level 1 Level 1 (0 points)
    Hi,

    But by using mv-command I created the situation of quite new backup and it failed too. Then there was no history.

    What on Finder's volume line: the directory at the main level of the external drive.

    There's no history because TM can't find the Backups.backupdb. folder, and/or, the data inside it is corrupted because of the attempt to remove the "in.Progress" file.

    What on Finder's volume line: the directory at the main level of the external drive.


    Ok, so it's the actual drive, not a "false volume."

    The original error: +*ERROR:-128, copy / to (null)+* is not one I've seen before this thread.
