I am using Time Machine to back up my 24" iMac to a dedicated 500GB LaCie Quadra.
My first backup completed OK but subsequent backups fail. I get an alert Time Machine Error - Unable to complete backup. An error occurred while creating the backup directory.
I have repaired Permissions and run Disk Utility.
In desperation, I reformatted to Lacie, set up Time Machine again and re-ran the backup with the same result.
Has anyone else experienced this error and can anyone assist with a solution.
I'm seeing the same issue. I'm using a Maxtor OneTouch drive though. It worked perfectly all day yesterday on my MacBookPro, this morning I started getting failures.
Yeah I have the same problem. I've tried it all. Reformatted, Repartitioned, Shorter Name, Deleted the plist, changed the USB cable....
Any one!?
Apple?!
I've tried formating the drive with no luck. What I'm seeing is that Time Machine is creating a directory on the drive called Backups.backupdb/Phill's Computer/2007-10-30-1330.inProgress but it is erroring out saying that it can't create the directory.
It is hard to believe that the format of a name could be causing the problem so many people have described.
Apple traditionally keeps things VERY simple, and when something does not work properly there is some basic problem.
My first reaction when seeing the problem was to reinitialize the external hard drive. For that I used the system CD, and of course there was an immediate sign that I had done something wrong in the past: The external hard disk (from LaCie) was not formated properly. In fact the documentation "before you install" says that the disk MUST be partitioned to even work with an Intel-based OS-X Mac. The documentation states:
"Erasing and formatting your disk
When you install Mac!OS!X, you can erase the destination disk you select. In the “Select
a Destination” pane of the Mac OS X Installer, click the Options button and then select
Erase and Install.
You can also partition your hard disk into several volumes before you install Mac!OS!X.
In the installer, choose Utilities > Disk Utility. In Disk Utility, click Partition. If you
partition the disk, you can select a disk format including Mac OS Extended (Journaled),
Mac OS Extended (Case-Sensitive), and Mac OS Extended (Case-Sensitive, Journaled). In
most cases, you should choose Mac OS Extended (Journaled).
Important: Partitioning the disk erases the entire disk, so make sure you back up your
files first. "
Once I was ready to partition my external drive, a warning came up:
The installer installs Mac OS X for Intel-based Macintosh computers only on drives with the GUID partition scheme. It installs Mac OS X for PowerPC-based Macintosh computers only on drives with the Apple partition scheme.
So I selected the GUID Partition option before proceeding.
Unfortunately, this had no effect on my problem, but it may have on yours.
Additionally, you should use the disk utility to verify both your internal and external disks. It may well be that the permissions in your internal drive need repair. Even if this has no effect on the problem with Time Machine, it is a good idea to go through these processes to avoid errors.
Finally, It would be a good idea to go to your LIBRARY folder and locate the PREFERENCES folder. Throw the "com.apple.TimeMachine.plist" in the trash and empty the trash, then restart your computer, fresh. This should reset everything back to the installation defaults.
Well, Juan. When all you mention had failed, I eventually discovered that characters such as a / did not allow TM to create a directory for backup.
For me, that is what solved the problem.
File naming--or here, computer naming--has always been a source of problems.
Mostly when pontuaction signs are included.
I had the same problem with TM when I tried to Erase and restart TM on my Acomdata external HD. However, I did the following and it worked.
Turn off Time Machine
Eject the external HD
Mount the external HD
Erase the contents of TM partition in external HD
Eject the external HD
Reboot the machine
Mount the external HD
Turn on Time Machine
Select the TM partition (Change Disk in TM Preferences)
TM starts to backup
I also had numerous problems initially with Time Machine which really took nearly a day to do the first back up and then bolixed up a number of hourly backups the next day. I received a number of error messages as you describe and found that successful backups are a folder in the Backups.backuptb file but at the bottom you will find a hollow folder (eg just a folder frame) with the admonition it is in progress (whether or not Finder shows backup activity - circling arrows). I trashed this file and thereafter backups worked fine. After it gets some backups done it seems also to become more stable and performs them faster.
I am having TM problems similar to those described in several comments. I am using a Maxtor Turbo III 1.4tb hard drive hooked up with Firewire 800. The "preparing" continues for longer than an hour and IF the copying begins (sometimes yes, sometimes no) I eventually get an error message "error copying files".
I have reformated the external drive, as per Apple Support recommendations so that the partition for TM is dedicated only to TM.
I am able to drag and drop files to the other partition of the external drive, so I know it is ok.
I have called Apple support three times. I have used disk utilities, repaired the disk, repaired disk permissions on the computer hard drive, zapped the parameter RAM (Command-Option-P-R). Everything else about the computer and hard drive seem ok, but I cannot get TM to work.
Of note--I have four 500 GB internal hard drives configured as RAID 5. I wondered if the RAID configuration might have something to do with the problem, but from reading the other comments, I think it is a Time Machine glitch rather than the computer configuration.
Another idea for those with problems. I have a Windows partition on my Mac Mini, and I think the read-only permissions on that partition (when booted into OS X) do not allow TM to access it....not sure why TM needs to write to the partition, but OK.
To fix this, I went into the Spotlight prefs and into "Privacy" and turned off Spotlight searching of that partition. TM then worked without problems.
So tiresome, I have partitioned 250 G for my 100g Mac book pro on a USB tethered Seagate drive which has a total size 500g. I erased and reformatted the drive using the Leopard utilities on the master disk. Then told Leopard she was the one via the dialogue. Everytime it gets a bit (8 gigs or so) done then Error window pops. Maybe I should take of the other usb's (disks) or firewire attachments? I checked to make sure that none of the other drives or partitions were including in the time machine preferences as well. Why does she hang? Why does the Leopard do this thang? Steven in Monaco
"It is hard to believe that the format of a name could be causing the problem so many people have described."
The use of the slash '/' in a file name has been a big no-no for years, the system uses this to delimit folders, so it's not used in a filename so as not to cause any confusion in the system.
