Time Machine is unable to back-up

I keep getting the error message from time machine saying "Unable to complete back-up. An error occurred while copying files to the back-up volume"
I have used time machine for almost two years with my WD 500gb External harddrive, but about 100 days ago it would allow me to back-up. I know there's plenty of room on the external, and I've tried everything...What shall I Do???

Hello, I don't use TM, but...
Have you looked through Pondini's extensive TM help site?

Can't imagine something not being covered there.

After installing lion time machine is unable to make back up

Yesterday I installed Lion and wantedbto make à back up with time machine, but this failled.
I received the following message:
Time machine was unable to acces the back up volume 'volume/timecapsule emd/iMac of Edwin.sparsebundle' That is used for making back ups. (error 111). This is a translation of the error message in Dutch.
Through time machine I tried to acces my pre kous back ups, but again I received an error. This read:
This processen could not be completed. There has been an unexpected error ( errorcode -6584)
When I open finder I can see my time capsule and it says That it is connected.
I expected no problems since I am using à time capsule from apple.
Is There somebody with a solution?

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"

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:

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?

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 backup unable to complete, error creating backup folder

All,
I am stumped. I have never had trouble with time machine performing backups before, but I am now. I recently purchased a new G-Drive 2T external drive. I was able to make a single complete time machine back up on it. The incremental backups now are the problem. On rare occaisions an incremental backup will run, but most of the time when it tries to perform an incremental backup, I get the error message
"Time Machine Error: Unable to complete backup. As error occurred while creating the backup folder."
My OS is 10.6.8 on a mid-2007 Intel iMac. Any suggestions on how to track this one down?
Thanks,
VSparrow

CoffeeBean,
You really should create your own thread rather than a "me too" as your situation can be very different than the OP's. What you are doing is called Thread Jacking and considered rude which I am sure is not your intent. Going forward please create your own thread.
Your issue may be with the G-Drive itself. My recommendation would be to try another EHD and re-test. If the problem disappears then you have narrowed it down to the EHD you are currently using. If the problem persists then please create your own thread and re-post.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." Tried suggestions I've seen on the forum.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." I've tried various suggestions I've seen on the forum but nothing has worked. TIme Machine worked fine for the last two years and just suddenly started having this problem every time. The only thing that was a little different is that the computer was off for a week while on vacation and then I added a large amount (20 GB) of photos. Now the requested backup size is 82GB, which is large, and process proceeds very slowly for 2-3 hours before failing with the message mentioned. I have more than enough available backup storage space for it. Before failing, Time Machine has backed up no more than 12GB or so of the backup. It fails during different files each time.
I've turned off the computer sleep feature, and I've checked that the NAS is set to never automatically power down. I normally backup over Wi-Fi, but I've also tried connecting to Ethernet and it still has the same problem. It's odd because I also have a MacBook Pro that is still backing up fine to the same NAS using the MacBook's Time Machine.
I am using an iMac with OS X 10.6.8 and an Iomega StorCenter ix2-200 NAS.
I have system logs that I can share if helpful. The logged messages vary a bit from run to run, but here are some messages that I've been seeing:
I always get this message near the beginning of the backup:
Event store UUIDs don't match for volume: Macintosh HD
I've gotten this messsage a number of times:

That looks like a problem was found with the file system (data) on the TM disk. I don't know the details, but OSX tried to recover it from the journal, and found extra data on the drive. Likely a result of the incompatibility mentioned above.

Something caused a disconnect. Can't tell from the log what it was.
I doubt it's a problem with something in OSX being damaged or corrupted, but reinstalling OSX isn't a major hassle, so might be worth a try.
To be incompatible with Snow Leopard, this NAS must be at least a couple of years old. It may be beginning to fail.
Contact the maker. See if there's an update to make it compatible with Snow Leopard. If so, that might fix it.
If not, or if that doesn't fix it, see if they have any diagnostics that will shed any light.

My Time Machine will no longer back up to my external disk for unknown reasons. It would not accept my password and said the disk is read-only and damaged. How can I copy my files to my Mac so I can repair it?

My Time Machine will no longer back up to my external drive for unknown reasons. It began after a series of power outages (my equipment is protected by a surge protector with battery backup), and was shut down correctly. Then it began by not recognizing my disk and my Time Machine password, although I am positive it was correct. I tried NUMEROUS times to get into it. It says the disk is damaged and needs to be erased and started over. How can I back up my files on my Mac so I can do that? I have no other disk to back up to. I found the files in a folder called "Backups.backupdb", and tried to copy them into a folder, but get the message "The volume has the wrong case sensitivity for a backup." The "lost+found" folder did copy for me. Will I just have to lose 4 years of backups?

Hi there,
I have the same issue. Usually hangs after 10K od sometimes after 18MB of backup file.
Config: iTunes 10.4., Win 7 64bit, iPhone 4 with iOS 4.3.3
I tried all of these without success:
- deleted backups via iTunes / Preferences
- deleted backups from sync folder
- created a new admin user and tried to sync
- reinstalled iTunes
- ran all Windows updates, restarted, reinstalled iTunes
- ran iTunes / Diagnostics (says everything okay, only info which is strange: diag says I am not a admin user, which is not correct)
Nothing helped. Who can help. I hope someone from Apple can take care, as I seem not to be the only one. Actually iTunes is the worst part about iPhone. Hope with iOS 5 and Cloud sync to get rid of iTunes.
Any hints welcome,
Cheers,
Miguel-KA

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."
http://docs.info.apple.com/article.html?artnum=106214
Then repair the backup/TM drive.

HT201250 Does Time Machine delete files in back-ups that are deleted on my Mac?

Does Time Machine delete files in back-ups that are deleted on my Mac? IOW....if I need to restore a whole back-up, I don't want to restore previously deleted files.

Does Time Machine delete files in back-ups that are deleted on my Mac?
Not immediately. When space starts to get tight, Time Machine will start to delete the oldest file(s) to make more room, but this won't occur for some time.
if I need to restore a whole back-up, I don't want to restore previously deleted files.
You won't if you choose to restore from a backup that occurred after the date that you deleted the file.
If you absolutely do not want to keep the file in your Time Machine backups at all, you do have the option to go into Time Machine, find the file, and manually delete all versions of the file from past dates.

Time Machine (OSX) doesn't back up files in Mount Point or Disk Image File

Hi all,
I have two disk images which are scripted to be mounted on login. These two disk images are always mounted to the same location. These two disk images are encrypted TrueCrypt volumes.
Time Machine (TM) will only back up the disk images the first time they are mounted, but not after that. As I modify documents within the volumes throughout the day, the modified timestamps are adjusted properly. However, TM does not back them up. TM never backs up the mount points which are two folders within my home directory.
Any ideas as to why neither the mount point or the image files are backed up? Do the image files have to be closed (unmounted) after being modified for TM to back them up?
Now if TM won't back up the image files because they are locked/open, then why does it back them up the first time even though they are mounted? Also, from what I've read, TM should back up any HFS+ drive which is mounted. Both these drives are HFS+, so it should back up the mount points? I can verify this by doing a 'mount' in the terminal, the following is echo'd back:
/dev/disk0s2 on / (hfs, local, journaled) (Main System Drive)
/dev/disk1 on /Users/username/Folder1 (hfs, local, nodev, nosuid, journaled, noowners, mounted by username) (First TrueCrypt volume)
/dev/disk2 on /Users/username/Folder2 (hfs, local, nodev, nosuid, journaled, noowners, mounted by username)(Second TrueCrypt volume)
Any ideas will help!
Thanks,
Chris

Here is the resolution:
Apparently time machine checks the parent folder's timestamp before moving into that folder to look for modified files.
So as I was modifying files, the timestamps on the volumes were changing but not the containing directory. Because of this, TimeMachine saw the parent directory had not changed, so did not look for the changed volumes inside.
So to resolve this, I wrote a simple touch script which touches the parent directory to match the modified volumes timestamp (if there is a modified volume).
Thanks,
Chris

Thanks - let it finish, but zero out data is unnecessary. That option is intended to thoroughly erase previously recorded data so that it cannot be recovered without sophisticated data recovery techniques.
Case sensitive is OK but I suggest you simply select Mac OS X Extended since "case sensitive" may complicate things for you in the future, should it be necessary to restore files to a case-ignorant volume.
Once it finishes, make sure it appears as a selectable option in Time Machine. If it does your problems are solved, but consider using Disk Utility and reformatting it. This time don't worry about zeroing unused space, and select Mac OS X Extended (Journaled). It will only take a few seconds this time.
For a more thorough description read Apple Support Communites contributor Pondini's FAQ: http://pondini.org/TM/5.html Read the pink box regarding the subject of case sensitivity.
