Error 18 after moving Time Machine to a bigger disk.

Good evening, I have been running Time Machine since August and everything was fine. Now my internal drive is getting full and I wanted to move it to a bigger drive and since I was doing that I figure why not time machine.
Here are the original stats.....
PowerMac G4 DP 1Ghz Quicksilver
1.25GB of RAM
Two internal Disks 74.5 (Formated) each with the secondary being my primary disk.
189.9 (Formated) GB Maxtor with 125GB at the end of the disk being devoted to Time Machine.
10.5.7
Following instructions and other users experiences from here
http://discussions.apple.com/thread.jspa?threadID=2028949&tstart=0
I copied my time machine disk using Disk Utility Restore to a Seagate FreeAgent 934GB (formated) disk, that work successfully and that was July 11th. A few days of mandatory backups and scheduled backups and everything worked well.
So today I decided to test the integrity of the backups made recently before I erased the 200GB Maxtor and move my HD to there. Since there were no other options available I partitioned the FreeAgent 1TB drive with Time Machine on there to a 74.5GB Partition at the bottom of the disk with a 5GB of blank free space in between TM and the test partition. That took about an hour to partition. Before I left for work I loaded off of my Retail Install DVD and ran a repair on the FreeAgent Drive since TM hasn't done a deep transversal and I wanted to force it.
According to my brother the repair went without a hitch, okay and he shut down the computer. When I came home started off of internal started a mandatory backup looked at the log message using the Time Machine Buddy Widget saw it was doing a deep transversal and I stepped out. When I came back I noticed Time Machine Menu had an "!" on it/in it saying there was an error, I loaded TM Buddy and it said there as an error 18 on the scheduled backup AFTER the mandatory backup.
Sarting standard backup
Volume at path /Volumes/ALN Perm Backup Disk does not appear to be the correct backup volume for this computer. (Cookies do not match)
Backup failed with error: 18
Now the mandatory backup that I did when I came back went smoothly and so did the next scheduled backup apparently, however I am not sure if this is just a one time error or something else until the next schedule backup sometime tomorrow (right now the drive has been ejected and TM turned off.)
So does anybody have any insight into the cause behind this.
My theory is it could be since I partitioned the new Time Machine Backup to a smaller size but then again I have in past extended the old Time Machine backup by utilizing some free space I left at the end of the drive which is ummm 15.4GB.
To clarify on the old Time Machine backup which is still holding original data...
42.00GB of an Old 10.4 Installation
125GB of Time Machine
15.4 of unformatted free space.
Hope all this information helps any questions please ask.
Have a good night

That particular error happens on occasion after switching a TM drive from one Mac to another, erasing your TM disk/partition, or attaching a new TM drive with the same name as an old one.
You can usually fix this by simply re-selecting your TM drive in TM Preferences > Change Disk.
Since your backups are now working, it's likely ok.

Moving time machine backups to another disk

I'm trying to move my time machine backups one external drive to another. I'm getting an error that says "The backup can’t be copied because the backup volume doesn’t have ownership enabled."
I was told I had to check off Ignore Permissions for this disk but I have no idea where to do that. it is not in GET INFO. I am using Snow Leopard.
Any ideas how I can copy the time machine files from one disk to another?
Thanks.

I recommend doing as I suggested. Cloning is the only correct way to backup a Time Machine backup drive. If you have data on the other drive you don't wish to lose then create a new partition on that drive. See the following:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.

How to resolve errors (-50 and -8058) when moving Time Machine backups to new disk?

I'm trying to move my Time Machine backups (about 600GB total) to a new external hard drive. I started the process last night, but after an hour or so received two errors, each repeated multiple times:
"The operation couldn't be completed because an unexpected error occurred (error code -8058)."
"The operation couldn't be completed because an unexpected error occurred (error code -50)."
I opted to cancel the file transfer. I looked up the error codes but I'm still not sure what they mean. I found an old support article about error code -50 (Mac OS X 10.1: "Error Code -50" Alert Appears When Copying Files From a Remote Disk) and an old support article about error code -8058 that doesn't appear to be entirely relevant to my issue (Mac OS X 10.4: Error -8058, unable to eject when trying to copy a disc in Finder). I've also found a number of Support Community discussions, none of which are particularly helpful.
Questions:
What do these two error codes mean? Are the files that cause these errors somehow corrupt?
If I click "Okay" when the error dialog appears, are the files that are causing the errors transferred or are they omitted from the transfer?
If I transfer the files and click "Okay" when the errors appear, or if I use Terminal and cp -R as suggested in Mac OS X 10.1: "Error Code -50" Alert Appears When Copying Files From a Remote Disk, will I have trouble recovering files from the new backup disk?
Do I need to verify/repair permissions on the original Time Machine disk before attempting the transfer?
Is there some other method I should use (e.g. Terminal instead of Finder) to transfer the backups?
Details:
MacBook Air
Mac OS 10.8.5
Both the old and new Time Machine disks are formatted Mac OS Extended (Journaled)

The two drives are handled as separate drives, even if they have the same name.
In essence, the old backups are from a drive that's no longer connected; see #E3 in the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.

After restore time machine log in twice

After moving files and programs from Mac Air to new Mac Pro, I have to login twice. I assume that this means the file restore occurred "inside" a logged in user, but how do you fix it?
Also curious is that even while I am typing something, the machine will time out due to inactivity and I'll have to log back in. This requires only one login screen.

The external drive does not seem to be the problem. I've tried the following:
- Deleted the /Library/Preferences/com.apple.TimeMachine.plist file and reconfigured TM.
- Do Time Machine backups on another disk. After initial full backup, the same behavior persisted.
- Exclude the external drive ("Synk_Archive" in the logs above) from TM backup. The behavior persisted.
- Unmount the external drive. The behavior persisted.
- Exclude Macintosh HD from TM backup. TM behaved normally and only backed up a few files per run!
- Repaired disk permissions on Macintosh HD. The behavior persisted.
So, there is something about Macintosh HD that is fooling TM into thinking there have been a million files changed every hour. Wiping and restoring my hard drive would be a desperate last resort and might not even solve the problem (since the trouble began right after replacing and restoring this drive). Anyone have another suggestion?

Make sure that no other Macs are backing up at the time.

Plug the power cable back into the back of the Tme Capsule
Wait a few minutes, then try a backup again.

FCP X does not recognize projects and events on USB drive after a time machine restore of the MBP macintosh disk

FCP X does not recognize projects and events on USB drive after a time machine restore of the MBP macintosh disk.
I upgraded from an i5 to an i7 15" MBP and restored my files using my time machine backup. All seemed to go ok, except I had to use the migration assistant because on the initial boot the MAC didn't recognize the backup database on the USB device. MAybe this is a hint.
Since when I start FCPX it too cannot finnd the project or event directories.
Before my upgrade, I had a choice of files either on the Macintosh disk or the 2TB USB disk.
Now only files on the Macintosh are accessible to FCPX. The USB drive is visible under events and project but it finds no projects or events.
Please help if you can.
Thanks
Barry

Thanks... alas no one has responded.
I think I have the structure that you are recommending.
I have a root level directory (Final Cut Events) with the files in them.
The puzzling thing is that it used to work before the migration!.
Anyway I'm going to move the contents to the root and see what happens.
On a slightly different note...
I also posted a question about CPU utilization. Can I ask a question or two?
While rendering a short clip, I noticed burst of disk activity when the render started (likely loading the media files into ram since I have about 4Gigs available, then almost no activity while the render is happening, then more disk activity when its done.
However the cpu activity is not as high as I would have expected since rendering requires a lot of cpu.
What is your experience? I know some render is done by the GPU, but in my older i5 the CPU was about 100%, now in my i7 its about 50%.
Please look at the attached utilization for CPU and disk activity.
Thanks for any thoughts... Barry

Error-code when launching Time Machine from MacBook Pro

I´ve get this error-code when launching Time Machine: An unaspected error has acourd (errorcode -6584)
Solution on this?

Sounds like OSX has lost track of where it is. Try a "full reset" of Time Machine, per #A4 in Time Machine - Troubleshooting.
If that doesn't help, try repairing your backups, per #A5 there.

After using time machine my users folder cannot be seen, but all information is still intact. Where did it go?

After using time machine my users folder cannot be seen, but all information is still intact. Where did it go?

This is a new feature or bug if you want to call it that in OS X 10.9.3
Until Apple fixes this, here is a temporary work around.
Copy and paste the following command in the Terminal and then hit Enter, followed by your password.
sudo ln -s /Users /Users\ Folder; ln -s /Users/Shared /Users/Shared\ Folder
This will put a link to the Users folder called "Users Folder" on your Hard Drive and a link to the Shared folder called "Shared Folder" inside of the Users folder.

Backup failing without any errors in sys prefrerences time machine

What happens: Time Machine scans, prepares, but does not actually back up. It does not report any errors through System Preferences > Time Machine.

Hi Pondini!
Thanks for your help.
I added the entire Time Machine disk to the spotlight privacy exception, waited for a bit, and removed it. From this line, I assume that it triggered the re-indexing of the drive:

Yup.
I think one of the issues was that I had the power settings to shut down disks.
That shouldn't be a problem, as they should "spin up" when necessary. Some external HDs respond to that setting, some don't -- they have their own settings. But unchecking the option sometimes fixes the problem, so at least you know what it is.

Any ideas?
The UUID mismatch message sent by backupd in your first post is because TM hasn't completed a backup, and isn't sure what's changed on your system and needs to be saved. So it does a "deep traversal," comparing your system to the backups (that's the "scanning" in the messages). That has to be repeated every time, until a backup is completed. On subsequent backups, it can use a log of changes that OSX keeps, and will be much quicker.
It sounds like something is corrupted, somewhere. Exclude your TM drive from Spotlight again,but leave it excluded. Verify your internal HD and Repair the TM drive again. (Unfortunately, those will find directory errors and the like, but not necessarily problems within files.)
Then try another backup.
How old is your external HD? Are you just starting with TM or that disk, or have you been backing-up successfully for a while?
Are you running any kind of Sync application? A couple of the messages mention some sort of sync, but I don't know enough about Spotlight to know whether that's relevant.
Are you running Windows via Parallels, VmWare, or the like?

What file or application are you trying to restore?

After restore, Time Machine backs up many files every time

After my root drive failed and I restored from a Time Machine backup, Time Machine now writes hundreds of thousands of files every backup -- though they only take up a few hundred megabytes. The backups take hours and backupd is usually using >50% of a CPU. Typical log messages are below. Interestingly, TM did *not* do a full backup after the system restore. I have already reindexed the drives that are being backed up, and the behavior didn't change.

What does error 19 on a Time Machine log mean?

I get this error number in the Time Machine log. I am having trouble with my back up drive and this is a piece of the puzzle as I don't know what it means.

Time Machine says "The Backup Disk is Not Available"

Line 0: I have a 400 GB external Western Digital drive that I leave plugged into an Airport Extreme. Previously, this worked mostly without a problem. It took some massaging to get it to work at first (I had to create the backup with the drive directly connected to the computer, and then I moved the drive over to the Airport Extreme and it was fine after that), but after that, it worked forever. This was in the previous version of the OS that I was running (snow leopard?). I very recently upgraded to Lion and it seemed to be OK, but then suddenly it gave me an error that said it had not been able to do a backup for 10 days. I thought "wow, that means it hasn't backed up since I upgraded to Lion."
So I told it to do a backup right away. It failed with the error "The backup disk is not available."
I unplugged the drive and plugged it back in. No go.
I tried to reselect the drive from within Time Machine preferences. It would not appear and in fact it kept forcing me to go to the Airport Extreme software. I did this and there was no obvious way to set anything up from within that software. I left everything as it was ("Enable file sharing" checked, "Secure shared disks" was at "with device password," and it was remembering the password in my keychain).
Go back to Time Machine preferences and the disk still doesn't show up. Force a reboot on the router, it still doesn't show up.
I brought the drive over to the computer and plugged it in directly, and everything was fine. It did a backup on the spot, it read the backup that was there, the drive showed up, etc. I formatted it just for the heck of it and started over completely and it was happy. I did a disk check and everything was fine. After leaving it on all night to complete a new backup, I unmounted the disk, brought it over to the Airport Extreme, plugged it back in, and now we go back to line 0 and rinse repeat.
Can someone please tell me how to get my drive to start working with Time Machine again?

It should not have worked in the first place.. when you moved it from the PC to the airport extreme.. that is not correct.. I don't know how SL managed to work around it.. but Lion obviously cannot.
You will need to start all over again..
Also note.. the flakey nature of this setup.. according to well respected people here AEBS with USB drive does not give reliable TM backups.. I would pay close attention to what they are saying. Time Capsule is more than a AEBS with a hard drive inside.. although exactly the difference I don't know.
But you can expect the current setup to not work, because it never should have.
