Time Capsule backup failed error -43?

Hi and Thanks to Anyone in Advance!
Below is the Time Capsule Error Log I get when doing a Time Machine Backup, wirelessly, on my 2T Time Capsule HD/Router.
Initial Setup and Backup done via ethernet, flawlessly, two months ago. Subsequent backups worked until about three days ago (Why, I have not a clue!)
Often, using Airport Utility, the Time Capsule does not appear. Turning off Computer Airport and on again, the disk becomes magically available for backup. Similar problem with wireless LAN printer...truly a pain. the printer needs to be deleted, and then added again in Print/Fax Preferences. (HP PhotoSmart C7250)
I used Disk Utility" on my Computer HD with a repair permissions, then performed a TC reset, physically, and reconfigured the TC on the LAN, trying a new name "gotyourback" for the backup. Backup begins every time, but keeps failing after about five minutes.
Hope this helps others with similar problem...
Again,
Thanks!

Ok, if it is only 2months old it shouldn't be a problem..internally at least.

I have the TC in bridge and it is picking up the domain from my router.. if your using the TC as the main router then you should have entries for gotbackup.local
You are running SL still?? Or lion?
I thought of simply restoring the computer's settings to what they were 4-5 days ago, via Time Machine.
The issue is network.. so restoring will not fix it.
But so is my overdue dentist appointment...really not looking forward to either!
My condolances to your dentist.
I think you need to dig a bit harder to get the cause.
Most importantly are you getting IP via dhcp from the TC?
Do you have ethernet and wireless connected at the same time?

Time machine backup fails; error creating folder. Western Digital drive requires password which is perhaps/likely the issue. I can't eliminate the password/encryption.

Time Machine backup fails on new WD external drive (My Passport Studio); error creating folder (after several hours of Time Machine apparently working).
Background: I purchased a Western Digital drive from an Apple Store to use for Time Machine backup. I followed the Western Digital instructions that came with the drive for Mac. I didn't get the Time Machine prompt which the instructions indicated I would receive--namely to select whether I want to encrypt my Time Macine backups. (I already have a Time Machine backup I use at another location, which is perhaps why I didn't receive a prompt.)
I decided to install the Western Digital utilities and security software that comes on the disk--with a view to potentially encrypting the disk (since I still wanted to have an encrypted backup since I was mobile). I forgot that (from experience 2-years previous) that I shouldn't install Western Digital software because it just makes life really complicated.
I tried several times to do a Time Machine backup with failures each time (error creating the backup folder). I tried to get help from WD but I don't think the technicians were following what my issue was. Potentially I was not helpful in explaining it. I deleted the WD applications from my system after the first contact with WD. However the problem persisted--I still had an encrypted hard drive. After three phone sessions with three different WD techs I still could not get a solution. (By the second call I was not at all interested in having an encrypted drive--I just wanted to format and restore the drive to an unencrypted state so that I could have SOME kind of Time Machine backup.)
I still don't have a solution--either to get Time Machine working with the WD encryption/password on the drive, or to remove the encryption so I can backup. Right now my options are to return the drive to the Apple Store -- or get a return authorization from WD. Seems crazy since the drive is fine and I have the working password.

Never install "helpful software" provided by WD and Seagate (or any HD mfg.)
All such stuff is fluff and nonsense that interferes with normal HD operation.
Always when you buy a new HD, format it for Mac and then use it to TM backup or clone a HD, or archive data.
Less is more on HD new out of box. A "blank brick", no fluff and cotton candy software

First Time Capsule Backup Failed - Time Machine Error

I bought my Time Capsule yesterday because I needed to backup my MacBook (which I bought 6 months ago). My plan was to backup the MacBook to the TC and then do an Erase and Install of my MacBook because of problems I'm having with the MacBook (it constantly hangs for a minute or more - sometimes up to 20 times a day). I thought an erase and install might fix the problem.
After setting up the Time Capsule and connecting it to the MacBook with a Cat 6 ethernet cable for the first backup I went to bed. I noticed that, when the backup started, it was taking approximately 5 minutes to backup the first Gb of data. As TC noted there was 80GB to backup I assumed this would take 6 or 7 hours to complete.
This morning when I checked the MacBook I discovered a message on the screen of my MacBook as follows -
Time Machine Error
Unable to complete bacup. An error occurred while copying files to the backup volume.
Nothing else! When I check the Time Machine in Finder, under Data there is the following -
Patricia Henwood’s MacBook_002332b6d076.sparsebundle and this is 50.82GB.
Can anyone suggest what I should do?
I bought the TC yesterday because all my other backup drives are Firewire and, of course, the MacBook doesn't have a Firewire port.
Should I just 'give up'? The MacBook is covered by Apple Care (and anyhow, even if it weren't it's only 6 months old so, presumably, it's still covered by Apple warranty). I understand from the salesman where I bought my TC that it, too, is covered by my Apple Care for the MacBook because I bought it to use with the MacBook.
Would the simplest solution be to make an appointment to take the MacBook and the TC to the genius bar and see if they can help?

Hi dealbata, happy to hear that yours is now up and running. My fourth TC backup attempt last night failed yet again (at 50.8GB) - I read in a previous thread (which I can no longer find but which was more than 5 pages long and went back to 2007) about many people who have had the message
Time Machine Error
Unable to complete backup. An error occurred while copying files to the backup volume.
From that thread, 'famouswolf' posted a solution which involved checking the system.log using Console.app (Utilities folder). In his case (and in mine) the problem was caused by corrupted files in iPhoto. The solution was to actually delete the files (all those that had an ERROR (-36) message next to them in the system.log. To delete them you have to locate them in your iPhoto Library file and delete them in the Finder. As you can imagine, this is a long and tedious process (I have over 8000 images in my iPhoto library) - frankly, I've already wasted two days on this - and the TC was bought so I could back up my MacBook and then discover what the REAL problem is with my MacBook (it hangs and/or crashes between 10 and 20 times a day :-((
So, I've bitten the bullet and re-partitioned my MacBook's hard drive and done a fresh install of OS X and the applications that came on the install DVD. I've then run Software Updater until everything is up to date and I am now in the course of doing a backup of the MacBook to the TC of the 'bare bones' of my system - it's only 14.3GB so I hoping it will work. Then I'll copy across what I need from my iMac and hope that tonight TC will backup everything.
Here's hoping!
Cheers
Tricia

Time Machine backups failing (error 22) on Time Capsule

Hi
I've been happily using my Time Capsule as a Time Machine backup for the last year or so. Two MacBooks have worked just fine on there, along with a network drive to store some of the wife's files which won't all fit on her Air.
Last night the firmware was updated on the TC and now whenever I try to do a backup on either my MacBook Pro or the MacBook Air I get the following error:
The backup disk image “/Volumes/Data-2/Adrian’s MacBook Pro.sparsebundle” could not be created (error 22).
The backups have always gone into a folder "Data" on the TM previously, and whenever a TM backup began I got a dark green TM disk icon on the desktop. Now this doesn't happen and the above error shows after the TM tries to prepare the disk.
I've tried deleting the .com.apple.timemachine.plist file from the Library Preferences to recreate that, no good. I've tried rebooting both TC and MBP. I've tried moving my old backup to a different folder to start afresh. Nothing has helped.
I also cannot access the old backups - I get this error:
An unexpected error occurred (error code -6584).
I have 1TB space remaining on my 2TB TC, so that shouldn't be an issue. I've tried rolling back the firmware using the Airport Utility as well, but this hasn't helped either.
I'm running OS X Lion 10.7.3 on moth MBP and MBA.
And with that I'm stumped as to why something that was so reliable should now suddenly stop working. The last backup was showing as yesterday at 21:22, which would have been just before I did the update. The only other thing I may have done last night was to map a network drive on the MBA so the wife can connect to her folder on the TC more easily.
Any ideas/solutions gratefully received! Thanks in advance!

Sounds like the backups may be damaged. Try to Repair them, per #A5 in Time Machine - Troubleshooting

Time Capsule backup fails with MobileMe synchronization

Update: this should have been posted to the Snow Leopard discussion area - was put here by accident. Posted as question to:
https://discussions.apple.com/message/16560106#16560106
After working flawlessly for some time, my Time Capsule has stopped completing backups (automatic or manual) whenever MobileMe syncing is enabled - Time Machine finds the Time Capsulse, scans my files for updates and starts the upload, but then it always hangs partway through. I've tried giving it as much as a day to see if it will continue to conclusion but it does not. I have to re-start my system just to clear the hangup, and I've had to disable automatic Time Machine backups to stop the issue happening all the time.
Curiously though, if I go into System Preferences --> MobileMe --> Sync and disable "Synchronize with MobileMe", reboot my computer and then still ensure the MobileMe icon in the top menu bar isn't swirling, I can then initiate a manual backup which runs all the way to conclusion without problem. I can then re-enable synchronization with MobileMe until I wish to do another Time Machine backup.
(If I disable Synchronize with MobileMe, but fail to reboot my computer, Time Machine still hangs. Also, sometimes after disabling synchronization and rebooting, the MobileMe sync icon in the menu bar may start showing activity - if I start a manual backup during that, or if it happens during a manual backup, the backup hangs and fails.)
After many repeated failures, Time Machine prompted me about an error and recommended wiping all the backups from the Time Capsule and starting with a fresh backup. I did that, but it did not resolve the issue.
Has anyone else seen this behaviour? Does anyone have any recommendations on how one can fix this?
Thanks very much!

Not much experience with either TM or MM, but...
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Time Capsule backup failed, volume read-only, can't delete

I've only been using Time Machine and Time Capsule for 2 months. This week it stopped working. First error message:
"Unable to complete backup. An error occurred while copying files to the backup volume."
Checking the Time Machine preferences, "Last backup" would read "backup failed"
When I got this error, all the wireless functions went offline, even thought the TC light was still green.
I would shut down, shut down the Time Capsule, shut off my modem reboot everything in order.
I would come back online, but after about 20 minutes to 1.5 hours into the next backup, same thing would happen again.
Next error message:
"Disk repair. The disk 'Backup of [my computer]' was not repairable by this computer. It is being made available to you with limited functionality. You must backup your data and reformat the drive."
Then: "Time Machine Error: The backup volume is read only. To select a different volume ... Time Machine preferences ... "
I spoke to someone at Apple, who sent me the Time Machine Troubleshooting page:
http://support.apple.com/kb/HT3275?viewlocale=en_US
Steps I went through:
1. updated my system software
2. updated the TC firmware to 7.4.1
3. dragged the sparsebundle to DiskUtility. It took a while (more than an hour?) but said the disk could not be repaired. When I tried again, the repair function wouldn't run.
4. tried to delete the sparsebundle, but it would choke at almost the end, sometimes it would just crash the finder, sometimes say "Sorry, an unexpected error occurred," sometimes "Operation cannot be completed because the item 'bands' is in use." I even tried to Stuff the bundle with 'delete original' checked, but the stuffing, after about 15 hours, jammed near the end (stuffed 20 gigs of 35 gigs).
5. tried to reselect the TC, and run backup anyways ... now it can't find the volume, back to the error messages and crashing Finder
6. checked password in Keychain, all ok.
Now what??
Do I use Airport Utility to erase it? At least TC is still showing up there. Or press the rest button on the back of the Time Capsule to reset to factory defaults?
I've resigned myself to losing my backups. Now I would just like to get it up and running again.
In hopes,
Linda

Now what??
Do I use Airport Utility to erase it? At least TC is still showing up there. Or press the rest button on the back of the Time Capsule to reset to factory defaults?
Yes, open Airport Utility and erase the drive. Once the sparsebundle is corrupted beyond repair there's little more you can do. However, do not reset the TC. Doing so will not erase the drive, but it will remove any custom configurations you may have setup for the router. Only if that part of the TC is also misbehaving should you use the reset button.

Time capsule backups failing - backup disk not available

All of a sudden I’m getting:
Time Machine could not complete the backup.
The backup disk is not available.
Time machine buddy’s log gives me:
Starting standard backup
Attempting to mount network destination using URL: afp://*.local/Data
NetAuthConnectToServerSync failed with error: 89 for url: afp://*.local/Data
Backup failed with error: 19
I’m connected to the Time Capsule right now (it’s how I connect to the web). I can see it in the shared list in Finder, although connection fails when trying to access it from Finder. What can I do?

Solution - I had the same thing happen to me with a Backup failed with error: 19 and what I did was this.
Stop any time machine backup in Time Machine preferences.
Go into Keychain Access in Utilities.
Go to search field and type "Local"
Delete any files that are of the kind "Time Machine Password". They should end in something like afpovertcp._tcp.local
Now turn on Time Machine back up in Preferences.
Click Select Disk and choose the volume.
You will be requested to enter the password and then it will take some time to establish the link and mount the backup volume. From there it will do a full back up.
Hope it works for you as well as it did for me.

Time Machine Backup Failed: Error (12): Link of previous volume failed

I am having troubles with Time Machine, backing up to a new Time Capsule, after I have switched one of the drives being backed up. I replaced a 250 GB external drive with a 500 GB drive, but have given it the same name (otherwise lots of links break). Now I get the following error everytime Time Machine runs:
Error (12): Link of previous volume failed for Athena Disk 2
Where 'Athena Disk 2' is an external USB drive being backed up, which was swapped with a new drive.
Disk Utility reports the drive is clean. I've seen a few other references to similar problems in the forum, but no solution. Console reports that the first (internal non-switched) drive has a bunch of files being backed up, but it seems to abort when it tries to backup the drive that was switched.
I've tried disabling backups, removing the Time Capsule disk and then setting it up again, in an attempt to 'reset' something, but to no avail.
Any ideas? I'm guessing there is a filesystem ID or something similar that Time Machine is using, and it notices that something has changed, but doesn't know what to do about it.
Thanks,
Dave Filip.

I'm having a similar problem, which seemed to start coincident with either a 10.5.6 update OR the replacement of my internal drive with a larger drive (I don't remember which...).
Time Machine backup logs now start similar to this one:

which leaves me with a few questions:
a) I don't have fresh backups, and that leaves my system a bit vulnerable. Can I fix this somehow?
b) I don't want to have to start over, but if I do how can I salvage the existing backups at least for the next year or so?
c) What the heck are those "CoreEndianFlipData" errors all about?
Thanks in advance.

Time Capsule Backup Fails on one Mac, fine on second Mac

Old MBP backs up fine to TC.
Newish MBA was working, now fails. All other network functions OK. Setup includes second APE (for AirTunes only), doesn't seem relevant/troublesome. Active users are administrators and are variously sharing in/out to other machines, screensharing enabled, B2MM enabled. Both machines running OSX10.5.5 & updated frequently, connected to same WLAN / same TC. Interrupts have occured (shutdowns, crashes, sleeps, and WLAN-switch to 2nd Windows WLAN to exploit W-printer). None of foregoing bothers MBP.
Attempted backup of MBA: TC menu icon displays what looks like letter "A" inside the rotating clock logo. Re-setup of TC via network settings doesn't resolve matters.
Clicking "backup now" results in long delay displaying "preparing" then failure message: Disk Repair / The disk "Backup of MBA was not repairable by this computer + a warning to backup asap & an instruction to re-format TC. Yet - no problem with MBP backup. MBA times out if I attempt to "enter time machine".

I find the above daunting, but can see that (1) it doesn't look much like the messages the MBP generates during successful bak, and (2) the target TC "beluga" seems to have been suffixed "-1" by the MBA and (3) seems to have declared itself read-only.
Now what?

I am having a similar problem. I have my 'old' MacBook backed up on my time machine, since long, and it still backs up on a regular basis.
Every back I try for my 'new' MacBook fails.
I wonder if I need to change something in the set up of the time machine, to have two computers backed up on it?
Anyone can offer me some help?
Thanks

Time Machine Backup Failing - error 27

Hi there,
I was backing up my Macbook to my external hard drive using time machine when someone disconnected the hard drive mid-backup. The backup failed and every subsequent backup now fails - time machine buddy spits out an error 27, which I think is a new one to this forum... output below:
Starting standard backup
Backing up to: /Volumes/Time Machine Backups/Backups.backupdb
No pre-backup thinning needed: 743.2 MB requested (including padding), 26.30 GB available
Waiting for index to be ready (917 > 0)
Stopping backupd because the backup volume was ejected!
Error writing to backup log. NSFileHandleOperationException:* -[NSConcreteFileHandle writeData:]: Input/output error
Copied 0 files (0 bytes) from volume Mac HD.
Error writing to backup log. NSFileHandleOperationException:* -[NSConcreteFileHandle writeData:]: Input/output error
Backup failed with error: 27
Can anyone assist? I have a feeling that subsequent backups are working but the backup log needs resetting somehow...
Thanks

Time Capsule: backup failed old backups lost

I'm having serious problems with my Time Capsule.
It is the newest Time Capsule 2TB connected to my new iMac and new installed MacOSLion.
This update already gives me problems with Wi-fi and now my Time Capsule is not working properly either.
I just left my iMac on for 3 days so it could make a backup.. after two days back-uping very slowly the message : back-up delayed appears, followed by the message : back-up failed. Al my previous back-ups made with my Time-Capsule are completly gone and I cannot back-up anything.
Had the problem several times, turning the TC on and of, reset it, reset Airport settings etc does NOT help. I'm having this problem for 2 months now.
Called Apple-Support about my Wi-fi problems, but 1,5 hour later and €30 poor they did not solve my problem. So, I lost faith in the Apple Support.
Any other suggestions for recovering previous back-ups and solving my constant and slow back-up failure problem?
Thanks in advance!

What does this mean
It means Time Machine is confused, and does not know what it is doing.
how do I fix it?
Try power off the Time Capsule
Count to ten
Then power the Time Capsule back on
Wait a few minutes and try a backup

Time capsule backup fail

I have a brand new 4th generation time capsule which just doe not successfully backup. I tried auto-setup and then did not find India in the country of use list. So then I had to reset and do a manual setting after successful setup my time machine floating info window shows the progress of backup but somehow stops for no reason. Can anyone please help....

Thanks for your response Pondini. Well, I think I was a bit unclear. My backup does not hangup it is being "interrupted" And I get a message that reads, "The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk."
There should be more to that message. As posted, see #C2 inTime Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it. If that doesn't help, post back with details, including all the messages, your setup, what you've done, and the results.
And unfortunately TC does NOT appear in Disk Utility to repair it.
That's correct, as far as it goes. Depending on what you find in #C2, it will lead you to #A5 in the same articlce, which shows how to use Disk Utility to repair your backups.

Why does time machine backup fail, error type -1

We have two Macbooks (2009 and 2010) running 10.6.8. My wife's computer came loaded with 10.5 and was upgraded to 10.6 while my mine came with 10.6 installed. Two months ago our time machine stopped doing backups of my wife's internal 120G(approx) hd while continuing to backup my 250G internal hd. My wife's hd was almost full so I thought that might be the problem. I replaced the hd with a much larger one but it still fails to make new backups. I was able to access the time machine to migrate information to the new hd. The time machine tries to backup but always fail to complete the backup due to a type -1 error. During the migration process I did not migrate applications in case the time mach app was corrupted. Both Macbooks are running time machine version 1.1.

The time machine tries to backup but always fail to complete the backup due to a type -1 error.
There are various things that can cause this error, so there are various solutions.

Time capsule backups fail because disks aren't recognised - how to fix?

Hi, all... I have a 500GB TC with a 2TB Western Digital drive attached, which I use for backing up three computers. My desktop iMac is connected to the TC by Ethernet cable, my laptop and my wife's laptop connect over wifi. The desktop and my wife's laptop back up to the WD drive. My laptop backs up to the TC internal drive.
Every few days (max, min is something like 1 day), I notice that the backups are all failing at the "Looking for backup disk" stage. That's both the iMac connected by Ethernet and the laptops on WiFi. The WiFi _signal_ is fine -- my laptops can see the network, browse to other destinations, download files at a good speed. The TC has a green light, and Airport Utility doesn't detect any issues.
But although the TC appears in the Finder Sidebar, it shows no disks. If I try to "Connect As" nothing happens.
I can resolve the issue by pulling the plug on the TC and re-powering it, and then doing the same with the WD disk. If I do that, both disks appear in the finder (with no need to "connect" to them) and backups proceed normally.
Backups can go on normally for anywhere between 8 hours and four days, but then I have to repeat the whole rigmarole to get them started again.
I'm beginning to suspect something to do with two backup processes over Ethernet and Wifi to two different backup disks "colliding" somehow and locking out the disks. I say this, because if I'm away for a week with my laptop, and my laptop does no backups to the TC in that week, then when I get back, the iMac is still backing up fine, even though five days is a long time compared to how often it seems to fail when all three machines are at home and backing up.
I don't want to have to keep pulling the plug, so does anyone have any ideas?
Many thanks!

Still not resolved this. However, I'm now absolutely SURE that it's something to do with colliding back-ups locking the TC up somehow.
I was at home for 3 weeks over Christmas, without using my work laptop. All through that time, the iMac continued backing up to the WD with no problems. Since then, though, I've been using my work laptop at home all day for a couple of weeks, and pretty much every afternoon, mid afternoon, the iMac alerts me that the backups could not be completed because the backup could not be found.
The TC shows up in the Finder sidebar still, and if I run Airport Utility I can access it and administer it. Once again, if you click on the TC in the Sidebar, it just says "Connecting" and shows no disks. However (and this is a new discovery), if I use the Airport Utility to "Disconnect All Users" from both the TCs internal disk and the WD external disk, the TC disk reappears in the Finder. The WD disk can only be made to reappear by power cycling it. But once that's done, backup can begin again as normal.
I therefore don't have to power cycle the TC to get the disks back.
So, it seems that something is happening that means that when two "users" are connected to the disks, having attepted a backup, they are locked, and can't be connected to.
Throughout all this, though, the laptop has continued to back-up normally to the TC internal drive, so IT can still see and connect to that drive. It's just the iMac that is somehow locked out of the TC and its external WD backup drive.
I do wish somebody would fix this!!!!

While trying to setup a time capsule backup to my MyBookLive external drive, I got the following error message: The network backup disk does not support the required AFP features. What's up with this?

This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).

Time Capsule backup failed error -43?
