Time Machine Error Unable to complete backup. An error occurred while ...

Hi,
I've looked all around the forums for the answer to this one and I'm still unable to get it. So I'm getting this error "Time Machine Error Unable to complete backup. An error occurred while linking files on the backup volume". This started happening after I turned off and on FileVault. I was having a problem with it and turning it on an off got rid of that problem, but created this one. I've noticed that when I shut down the computer and filevault accesses the TM hard drive, it can back up.....but then when I'm logged on, or I want it to back up I get the error. I've tried fixing the drive, removing the in progress file and resetting the PRAM (i think that's what it was called). I'm starting to run out of options and have no other drive to back all this info on to reformat it.
I really don't want to loose all my stuff.
Please help!

Usually this message happens when you replace an external disk that was being backed-up by Time Machine with another one of the same name.
Since File Vault works by making a sparse image of your home folder, and it's treated as a volume just as a HD is, that's probably what's happening here: the new sparse image has the same name as the old one, but isn't the old one.
First, consider whether you really need File Vault. It doesn't work well with Time Machine: you can't see or restore individual items in your home folder, and it only gets backed-up when you log out.
If you have a lot of other things, say photos, videos, and/or music that don't need to be encrypted, perhaps there's an easier way to secure our sensitive data. You can create an encrypted disk image via Disk Utility (in your Applications/Utilities folder), then copy the sensitive documents into it. Then the rest of your home folder is backed-up normally, and individual items can be viewed and restored in the usual fashion.
But if you do continue using FileVault, you may have to use TM to delete all backups of it, via the instructions in item #12 of the Frequently Asked Questions *User Tip* at the top of this forum. That should then allow the new version of your encrypted home folder to be backed-up by TM.

Time machine error unable to complete backup. an error occured

Hi All,
I have a question: i try to set up timemachine. Everything seems to work. but i cant get the first backup, it gives me the follow error: time machine error unable to complete backup. an error occured while copying files to the backup volume
My setup: an internet wireless router with a ethernet connection. On the ethernet connection i have a FreeCom Network Drive.
The Freecom Network drive have fat32, i think i cant format the netwerk drive cause there is some software on it, that give me access to my network drive via lan.
I configure that i can have acces to my netwerk drive. I can setup it from Time Machine, and Time Machine starts to put data on my network drive. After a while (mostly between 500mb-1,2 GB) it gives me the follow error: time machine error unable to complete backup. an error occured while copying files to the backup volume.
What to do???

Hi Norm,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
(Repair both Drives)
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

HT3275 what do I do when time machine says: Unable to complete backup. An error occurred while creating the backup folder?

I am trying to back up my imac using an external storage: My passport Studio 1TB. Each time it trys to back up Time machine says: Unable to complete back up. An error occurred while creating the backup folder. Does anyone know how I can fix this problem? Thanks

Plowie,
Do a search in Discussions, "An error occurred while creating the backup folder."
Many of us are having this problem and no fix has been offered, that I could find.
Unless you call "eject the external HDD; turn off; turn back on" a fix. That's what I have to do every 2 or 3 days; I even have to "force eject", with the concomitant warning message that you could lose data, etc.

"Time Machine is unable to complete backup" error message

I've tried to run Time Machine 3 times since last night and each time it gets through about 85 GB with about 150 GB remaining. Then a message comes up that says "Unable to complete backup. An error occurred while copying files to the backup volume." I checked the Support Troubleshooting section before the last attempt, and reformatted the disk as it suggested. (The disk is a new Western Digital 500 GB). Based on the response to a similar discussion posted recently, I went into my Console and copied the below. Obviously this is all Greek to me, so if anyone has any insight on how I can get Time Machine to work as it's intended, I'd sure appreciate it!

Well now I've got a whole new, much bigger problem. I did the renaming and then went through the indexing procedure for the 3 partitions of my main drive. So after that I did a restart. However, after the restart, there were (and are) no icons on my desktop. Nothing for my drives, files, etc. The only thing that shows is the dock at the bottom. If I open an application from the dock, it opens fine and then I've got the menu bar at the top. But the finder won't open. When this first happened, and I checked the Spotlight icon top right, it said was 'estimating index time" for both of my external hard drives (which I did not select when I was in the Privacy tab, etc.). One of those has my iPhoto library of 5,000+ photos and one is the empty back-up drive for Time Machine. Those "estimating indexing time" messages stayed for some time but have now gone away (without ever indicating that indexing was taking place), but still no change. I've restarted again and it's the same. Help!

HT3275 The error message I get with Time Machine is 'Unable to complete backup. An error occurred while creating the backup folder.' Any idea how I solve this problem?

I am a little perplexed. The Time Machine does seem to be backing up my data but I continually get the following message displayed on my screen 'Unable to complete backup. An error occurred while creating the backup folder.' I am using a WD My Passport for Mac portable hard disk drive.

Hi Peter,
http://pondini.org/TM/C10.html

Time Machine Issue-Unable to complete backup. An error occurred while creating the backup folder.

Unable to complete backup. An error occurred while creating the backup folder.

As usual, backups worked for a few days. Failed again on wakeup this morning...
Starting standard backup

Error: (22) setxattr for key:com.apple.backupd.ModelID path:/Volumes/TM Backup/Backups.backupdb/David's Mac Mini size:10
Backup failed with error: 2
I've searched Discussions and have seen the exact same error messages with all kinds of Macs and ext HDs, both USB and FW. I can't believe it's a 'failing HD' since it works for a few days; and that it's been going on for months now. Seems like the ext HD would have actually failed by now if that was the case.
I wish I could figure out why three different errors are reported: (-50), (22), and :2

Time Machine says, Unable to Complete Backup

There seem to be a lot of variants of my problem on this forum, but each one is different. After several months working well, about 3 weeks ago the Time Machine on my iMac quit doing its backups to my Time Capsule. I get the message, "Unable to complete backup. An error occurred while creating the backup directory."
Repairing permissions, restarting the computer, and unplugging/replugging the Time Capsule did not help. Manually requesting a backup doesn't work either.
My computer knowledge is rather rudimentary, so if you reply, please please use step-by-step explanations, define any acronyms, etc.
Another question: is there a way to connect the Time Capsule to my computer by cable, and use it as effectively just an external drive. e.g. backing up by manual copying?
Here is the system log from a failed backup:

Ken,
This thread may be of interest if you have not already read it.
http://discussions.apple.com/thread.jspa?messageID=8354256&#8354256
Did you interrupt a backup at some stage or did you not eject the Time Capsule at the conclusion of a previous backup before shutting down your Mac?
Is there sufficient free space on Time Capsule to cater for your backups? The backup volume needs to be about 3 times the size of your Mac HD used space.

Time machine is unable to complete backup

Three days ago my time machine stopped backing up my files with the error message, "Unable to complete backup. An error occurred while copying files to the backup volume."
Apple support took me through a partion of the the backup hard drive. I then used Utilities to make sure there was no problem with my harddrive, it's files and even the back up hard drive. Once again I received the failed message. I've done the partion process three times with no success in backing up my hard drive.
I've notice on line several people having time machine problems within last 5 days, this cluster raises an interesting red flag with time machine program.
What do I do now? Is there any way to reload the time machine program. My suspicion is the program has a flaw since every other fix has been tried.
HELP!!!

You may have to re-install the system to re-install time machine.
This error generally represents a problem communicating with the backup device ie. bad usb/firewire/wirelessconnection to the device. Do you have another external device you could try it with? sometimes the external device is at fault.

My time machine says unable to complete backup. An error occurred while copying files to the backup volume

It won't give me any more details, how do i find out where the problem is?

I've been doing more research on this, i downloaded the time machine buddy and this is what i got.
Starting standard backup
Backing up to: /Volumes/Time Machine Backups/Backups.backupdb
Event store UUIDs don't match for volume: Macintosh HD
Node requires deep traversal:/ reason:kFSEDBEventFlagMustScanSubDirs|kFSEDBEventFlagReasonEventDBUntrustable|
I'm not seeing info on this error anywhere.

Time machine says unable to complete backup as file is too large

I have a 500 GB Time capsule and it says when carrying out a back up that it can't be completed as the file size is too large, back up requires 233.01 GB and only 211.95 GB are avaliable. Does this mean i need to buy a bigger Time capsule/external hard drive?

Thanks for the help.
From what I can work out I think as I don't have my computer on all the time long enough to carry out a back up it now wants to do another full back up and I don't have the space on the Time capsule to do that. I will go into a Apple store to check I am right but it looks like I will need to buy a bigger externel hard drive.
Thanks again

Time Machine Error "Unable to complete backup"

I have not backed up my hard drive for about 30 days. When I plug my external hard drive in, Time Machine "prepares backup" for a while, then gives me the following message:
*Time Machine Error*
Unable to complete backup. An error occurred while copying files to the backup volume.
I tried unplugging and re-plugging, rebooting my computer, trashing the ".inprogress" backup file and restarting. It did not help. While it time machine is preparing the backup, my computer runs crazy slow, with the rainbow pinwheel spinning for about 5-10 seconds just about every time I click the mouse, in any program.
Per someone's suggestion, I put "sudo grep backupd /var/log/system.log" into terminal, and this is what came up:
"No pre-backup thinning needed: 4.98 GB requested (including padding), 70.16 GB available
Waiting for index to be ready (906 > 0)
Unable to rebuild path cache for source item. Partial source path:
Indexing a file failed. Returned -12 for: /Applications/iChat.app, /Volumes/Time Machine Backups 1/Backups.backupdb/My Computer (2)/2011-01-13-113417.inProgress/CB0D491E-EF04-48A0-9AE9-32AE43E9209C/Macintosh HD/Applications/iChat.app
Aborting backup because indexing a file failed.
Stopping backup."
This time, it was apparently iChat, but in each of the three times I've tried to backup and gotten this error message, a different file has been the culprit for the indexing error.
Any suggestions?

Time Machine Error: Unable to complete backup. An error occurred while creating the backup folder.

Hi,
I'm using time machine to do my backups but now is not working.
I'm getting the following error:

Thanks for your help

Time Machine Error: Unable to complete backup. An error ocurred while copy

Hi.
Everytime Time Machine tries to update my backup copy is gives me the same error: "Unable to complete backup. An error ocurred while copying files to the backup volume."
What's going on and how can I solve this?
Thanks.
Regards,
Telmo

I have had this problem and solved it. It began when I upgraded to Snow Leopard server after a hard drive failure under Leopard Server. My problem was caused by a number of bad files.
To locate the files that are stopping the backup, open the Console utility in the Utilities folder. On the top left, show the Log List, and select the ALL Messages. Then in the search box, top right, enter .backup , this will locate all the backup logs. Go to the bottom of the log and locate the log that reads "stopping backup." Then, look at the log directly after "stopping backup," this log should contain the error message. In my case the log had an error -41, and the file path and name were listed. After locating and removing the bad file, run your backup again. If you have this problem again, repeat this process.
I had about 15 files with this problem, and oddly they all came from either a very old Mac OS X backup or had been moved from a Window XP computer using file sharing.
Hope this helps.

How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.

How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.
When I start a backup. Time Machine says "Oldest Backup: None; Latest Backup: None", so it seems like it should do a complete backup, but it only does a partial.

Aside from the size of my backup drive, which I will increase at some point, I'd really like to have time machine backing up all system folders, especially Applications. How to I reset this hidden exclusions?
Thanks,

Time machine is unable to auto-backup....

Time machine is unable to auto-backup as it is unable to detect time capsule disk. However it will do a backup once the disk is manually located using 'select disk' option. This problem started when our house network was upgraded to fibre optic network. Earlier it was working prefectly fine on cable network. Would appreciate if someone can advise the solution to the problem.

Looks like a mounting issue perhaps? Often solved by power-cycling.
