Time machine locks up when browsing backups.
I have just started using time machine. It did a full back up 3 days ago and is ow doing hourly backups. My problem is browsing the backups, the TM window opens full screen and the time line on the right animates, I can click on a date which then comes to the front but if I click on anything, TM locks upand wont respond, None of the buttons work,no spinning 'wait' icon and the only way out is to force quit. I did see another thread suggesting that virus barrier could be the problem, but I uninstalled virus barrier some time ago after the trial subscription ran out.
Any suggestions?
Many thanks

You can't repair permissions on a non-OSX volume. It sounds like something on one of them, probably the iTunes drive, is corrupted. +*Repair Disk+* instead.
When I try to stop the backup, it won't stop and I'm forced to shutdown my mac using the power button because nothing else seems to work
See #D6 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum). If it's locking up that badly, have the Activity Monitor window visible and ready before starting a backup.
I'm a bit nervous that my 500 GB drive is failing.
Quite possible.
All of my media is there and I'm concerned I'll lose it all. Could it be anything else though?
Sure. If +*Repair Disk+* says it "appears to be ok," and the problem persists, exclude it from backups temporarily, per #10 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
If the problem stops, you know it's something to do with that drive.
If not, Verify your internal HD and, while you're at it, Repair the Time Machine drive, too.
If it does appear to be the iTunes drive, check all the connections; try different port(s) and cables, and combinations of the two (a plug that works fine in one port may not make good contact in another).
Also check the power connections, if the drive has it's own power supply. And be sure it's plugged-in to a known good outlet: better, a good-quality surge protector; best, the same U.P.S. system that your iMac is on.

Why does my new external drive used by time machine keep starting when no backup is being done
Got a new 2 TB Seagate GoFlex for Mac and run it over WireFire 800 because the old Western Digital was having a hard time starting up which held up the boot. I have a 2.8 Ghz Core 2 Duo desktop with 3 GB of RAM. Running OS X 10.6.8.
Seems like the every 10 minutes or so, I hear the external drive start up even when no backup is scheduled. I spend most of my time in a Win XP Parallels virtual machine.
What's up?Why would you say that? The drive has passed several Seagate verifys. It does not exhibit any issues. It is doing backups and I copied my 39 GB virtual machine to it with no issues.
Seems to me a drive does not just start up by itself, no? -
Time Machine Locks up at "Preparing backup..."
Using a 1 TB Time Capsule for Time Machine Backup of my MAcBook Pro (MacBook Pro, OS X Mavericks (10.9.5), 8GB Ram, 2.2GHz Intel Core i7, 1TB). Occasionally, it stops backing up properly. In Time Machine Preferences, it finds the disk but seems to get hung up "Preparing backup..."
In the past when this happened, I rebooted my cable modem and then rebooted my Time Capsule and the next backup started working fine. That no longer seems to work. It just keeps "Preparing backup...."
Any suggestions?Do a verify of the backup.. it could be stuck with inprogress file from previous failed backup.

Time Machine locking up on initial backup
I'm running TM on a G5 XServe, backing up networked student folders. It was working at the beginning of the year, however it has been giving me trouble lately. TM is backing up to a 1TB iSCSI networked SAN unit. Over Xmas, the SAN lost two hard drives and crashed. This is when the trouble started.
We rebuilt the SAN unit and I got another 1TB iSCSI drive configured for TM. Three times I've tried to get it running and it'll always crash on the second backup (one hour after the initial backup).
This last time the initial backup was pretty big (462GB I think) and it crashed on the second backup an hour later. But there shouldn't have been any new data as that second backup was at 12:13 a.m. (nobody around).
Any ideas as to why TM wants to crash?

Click in the message area (that will outline it in blue), press Cmd+A to select all, then Cmd+C to copy everything to your clipboard; then paste it here.
This message was last after three UUID's don't match for all three internal drives (but that supposed to be normal for a first backup).
Correct. So is the "deep traversal" message. Since TM isn't sure what's on the disks with the UUID problems, it has to do the deep traversal, comparing every directory (folder) on your system with it's backups. That is, of course, a lengthy procedure, and the message is not an error message -- it's just to let you know the Preparing phase will be a long one.

Finder locking up when browsing Time capsule hard drive
Finder locking up when browsing Time capsule hard drive
I am able to browse the hard drive preview some videos or open files for around 5-10 mins then Finder locks up. Internet still works and I can relaunch Finder and then works for a while again. It sounds like the hard drive is just going to sleep. I watch some films directly off of the hard drive through VLC and these just stop wilst viewing them.
I am on 10.6.2 working on the 5GHZ channel on dual band time capsule.
It is really annoying I have tried a few things like resetting the DCHP Lease. But it seems to be specific to the hard drive as the internet still works fine. It is really annoying as it jams up the finder really awkwardly.
Ant ideas most wanted
ThanksAre you browsing/viewing files in Time Machine backups on your Time Capsule, or files you've put there yourself?
If the files are Time Machine backups, use the Time Machine interface (the "Star Wars" display), via the Time Machine icon in your dock (or in your Applications/Utilities folder) to see what's there. Backups are not meant to be used; they're duplicates that can be restored in case of a problem with the originals on your system.
If the files are things you put there, you'll do better browsing, searching, or re-posting in the +Time Capsule+ forum, hiding in the +Digital Life+ section, at: http://discussions.apple.com/forum.jspa?forumID=1253 -
I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Machine, there are only about 5 backups recorded on the ext. hard drive. There were many more before. Any idea what happened and if I have to buy a new back up hard drive?
Hallo Kieth ,
I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
Thanks for your interest and advice.

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.Hi I'd like to jump in here. Your app showed me this:
Time Machine:
Skip System Files: NO
Mobile backups: OFF
Auto backup: YES
Volumes being backed up:
Macintosh HD: Disk size: 749.3 GB Disk used: 453.81 GB
Destinations:
Plastic Wrapper [Local] (Last used)
Total size: 999.86 GB
Total number of backups: 64
Oldest backup: 2013-07-24 23:25:11 +0000
Last backup: 2013-11-17 01:40:47 +0000
Size of backup disk: Too small
Backup size 999.86 GB < (Disk used 453.81 GB X 3)
Time Machine details may not be accurate.
All volumes being backed up may not be listed.
/sbin excluded from backup!
/usr excluded from backup!
/System excluded from backup!
/bin excluded from backup!
/private excluded from backup!
/Library excluded from backup!
/Applications excluded from backup!
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,

I bought an external hard drive for backups to use with Time Machine, but however when I try to connect it with the other windows laptop it doesn't work ? intact it doesn't work on any other device except my MAC ?
Do not worry about it.
Time Machine needs that your external drive is formatted in HFS+, or better known as "Mac OS Extended (Journaled)". This filesystem is used by Apple on Macs and Windows cannot read or write drives formatted with this filesystem, being this the reason why all your devices do not read the external drive except your Mac.
You can only use your external drive to make Time Machine drives. If you store anything different, you may damage the Time Machine structure, so it is better not to use it as a drive to store other data. Instead, get another external drive to do it or create a second partition on the external drive formatted in FAT32 by using Disk Utility > http://pondini.org/OSX/DU3.html FAT32 can be read by Windows PCs -
I get this error message when I try to back up my laptop:
' Time machine could not complete the backup. The backup disc image "/Volumes/Data/Lou Ann Buesing's Mac Book Pro. sparse bundle' is already in use. "
Anyone know how to fix it?Reboot the TC.. Sometimes you need to reboot the whole network.
This is what comes of Lion and then made worse in Mountain Lion of Apple not spending enough time to fix the bugs.

Backing up to a thumb drive - time machine doesn't delete older backups when it's full. I will have to erase and re-do the drive. Why?
You are both right.
Time Machine can backup FROM:
It cannot back up a USB thumb drive.
Time Machine can backup TO:
•A USB thumb drive (but most aren't large enough, and are very, very slow) -
Time Machine - Can't Explore Previous Backups, Can't Open Image!
I have a two-fold problem with my Time Machine.
1. I plugged in my USB hard drive into my Macbook Pro, and let it backup. Then, I plugged it into an Airport Extreme n (Fast Ethernet) and it resumed the backups successfully. But, regardless of whether I had it plugged in through USB or wirelessly, I could not see on the Time Machine program any previous backups (i.e. flip through past times).
I had previously been able to see older backups, before all the time machine updates, and when the hard drive had been plugged in through USB only. But after all the updates, my time machine backup failed to recognize, and I deleted the whole thing.
One difference I noticed with the backups with prior to and after the updates, was that before, it would have a backup folder, whereas now, it uses an image format. Which brings me to:
2. When time machine is doing a backup, I am able to see the image loaded. I can browse through it and see all the backups through the finder.
When Time Machine is not backing up anymore, however, I can no longer see the image. When clicking on the “sparsebundle,” I get the following error:
The following disk images failed to mount
Image: Macbook Pro_001b….
Reason: Operation not supported on socket
Anybody know why these two issues occur?
Thank you for your help!

Time Machine: Repeated errors when backing up for the first time using a new external firewire drive
My Iomega 500GB firewire external drive failed on me last week and I have just replaced it with an identical model. I used to use the old drive with Time Machine on my MacBook Pro running 10.5.8 with no issues, until the drive had a hardware failure and stopped spinning up, hence the replacement.
Two days ago I tried using Time Machine for the first time with the replacement external drive. The backup failed and each subsequent backup attempt has failed since then with a different error each time. The drive cannot be ejected using Finder (Finder says disk is in use and cannot be ejected even when no processes are running except for Finder and Time Machine has been disabled), by dragging it to the dock (hangs computer which can only be fixed by a hard reboot), in Disk Utilities (drive cannot be unmounted) or in Terminal ("no such file or directory").
The first backup attempt failed after 3 hours of "preparing" with the message "The backup was not performed because an error occured while creating backup directory".
I tried repairing the disk in Disk Utilities and Disk Utilities said the drive was OK ("the volume Time Machine Backups appears to be OK"). I tried ejecting the drive (hard reboot of computer and disconnecting the drive), plugging it back in again and trying again.
This time it started backing up, then failed after a few minutes with the message "an error occured while copying files to the backup volume". I had a look at the troubleshooting suggested on http://web.me.com/pondini/Time_Machine/C3.html and followed instructions. It failed again, so I did a full reset as per http://web.me.com/pondini/Time_Machine/A4.html.
It failed again, so I tried reparing the drive again in Disk Utilities and again it said it was OK. I tried using different cables and ports (Firewire 400 instead of Firewire 800), and backups still fail.
I have turned off anti-virus scanning (Sophos). I have tried excluding it from Spotlight but this causes an error message from Spotlight. I have tried trashing the com.apple.TimeMachine.plist file and rebooting. I have tried selecting deselecting the drive as the back up in Time Machine preferences, selecting "None", then "Stop Backing Up" then quitting preferences, rebooting, disconnecting the drive, reconnecting the drive and selecting the drive again as the backup disk in Time Machine preferences. I have tried erasing the drive completely, rebooting, and trying to back up again.
None of these have worked. This is a brand new drive and I do not want to have to replace it again if I do not have to.
Does anyone have any suggestions? Thank you.Hello, some possible clues...
Should you click “Start New Backup”? Not yet! If you see the dialog above, your existing Time Machine backup is corrupt, and you might not be able to recover data from it. But you can save a copy of the corrupt bundle and, perhaps, extract some data from it if needed.
Ask yourself if Time Machine has saved data you might need before deciding what to do next:
If you are sure you won’t need anything backed up before today, click “Start New Backup” and let Time Machine do its thing.
Otherwise, click “Back Up Later” and save a copy before letting Time Machine start a new backup. Just look for a file called “computername.sparsebundle” (for network backups) or “Backups.backupdb” (for local ones) and create a copy with a different name. You can open sparsebundle files with DiskImageMounter and browse them like any other disk. More information is available here.
There you go. If you click “Start New Backup” when you see this dialog box, Time Machine will erase all of your old backup data and start a new bundle. It won’t be corrupt, but it will be empty.
Note that you can manually initiate a Time Machine backup integrity check by option-clicking the “Time Machine” icon in the menu bar and selecting “Verify Backups.”
http://blog.fosketts.net/2010/08/11/time-machine-completed-verification-backups- improve-reliability-time-machine-create-backup/
According to This Time Machine resource “This appears only on Snow Leopard, and started with the Time Capsule Backup Update 1.0 in mid-May of 2010. It also seems to have been included in the 10.6.3 v1.1 update and 10.6.4.”
So, what can you do about it? Grin and bear it, it seems, until Apple fixes it.
One thing you can do to make the backup take less time is to connect your machine to your Time Capsule or other backup drive via Ethernet for the duration of the initial backup.

I updated from Snow Leopard OS X 10.6.8 to Mountain Lion OS X 10.8.2 on my MacBook Pro
I used disk utility to restore my external hardrive because I read somewhere that that would fix the problem.
It did fix the problem but only temporarily. I was able to view my backups from Snow Leopard, but as soon as I tried to backup again, time machine was stuck
"preparing to backup" for 5 hours and when I quit the prepare I could no longer access my previous backups.So what happens if you go to System Preferences > Security & Privacy > General? Are you able to go there at all? If you are able to go there, can you unlock the preferences using the lock in the lower left and your login name and password?
If you are able to do this, can you change the "Allow applications downloaded from:" to Anywhere?
Best of luck. -
Connected a WD My Book pro to my G5 PM running OS 10.5.1. After a few minutes into the first backup it failed the backup with the message: Time Machine Error - Unable to complete backup. An error occurred while creating the backup directory.
Tried deleting the "in-progress" file, but the disk is locked and will not unlock. Cannot unmount, repair or erase with DU, and cannot unlock.
Tried disconnecting and reconnecting power to the backup disk, now the computer hangs trying to connect to the backup disk.
Appreciate any suggestionsTry shutting down and resetting the PRAM.
