Time machine is getting stuck whilst 'calculating changes'

Updated my external HDD to use for TIme Machine. 3 weeks later and TM is trying to back up but getting stuck on 'calculating changes. I can't access or eject the drive whist that's happening so have to just pull the USB and restart.
After that it's fine, but I'm worried that not ejecting properly might damage the drive or the content. Any ideas?

Time Machine backup gets stuck - Please help

Hi all,
I'm backing up my MBP via ethernet to a Time Capsule. The incremental backups take forever and are driving me nuts. The backups seem to be getting stuck midway. The disk sounds like it's spinning but the progress bar doesn't move. Also, it seems to be copying over too many files every hour, like >60000 or so (log below). I doubt that so many files get modified every hour.
I've tried everything (I could think of and find on the discussion boards) like deleting the sparsebundle, deleting the entire backup drive, playing with the backup frequency, nothing works.
Please help!!
Thanks,
DB

The indication that the backup completed successfully is the best evidence that it did. If you want something more explicit, you can proceed as below.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo tmutil compare
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
Files that you’ve excluded from backup, or that are excluded automatically, are ignored.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

Time machine - 1st backup - stuck on calculating size

Hello,
I'm running Time Machine for the first time on OSX Lion.
I've bought a external 2,5inch HD of 1TB.
I formatted it to Mac Os X Extended (Journaled). I added the disk as a time machine backup and ran the "backup now".
It's stuck on Calculating Size for about 30 minutes.
Does this take this long? Can't remember it took so long under SL.
thanks in advance,
greetings

But..right around the moment of 70% or so on the progress bar, (with about 20 minutes remaining) the "restore was successful" box pops up and prompts me to restart the machine. Upon restart I can not get past the white apple screen. I've tried just installing OSX
When you do that, has all your data been restored? If so, just download and install the "combo" update to get back to 10.6.6.
and then using migration assistant, but migration assistant does not recognize my time machine external. Any thoughts?
Try repairing your backups, per #A5 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).

Time Capsule / Time Machine stuck on 'calculating changes'

Time Machine has not backed up to my Time Capsule for the last several weeks on my MacBook Pro. It is constantly stuck on 'calculating changes' for hours. I have tried other suggestions I have found in the forum like verify and repair disc on both my internal HDD and on the time capsule drive. No errors were found on either drive. I normally backup via wifi and I have also tried plugging directly into the time capsule with an ethernet cord. It doesn't make any difference either with wifi or ethernet.
The time capsule drive is full, but I just assumed that Time Machine would erase the oldest backups and continue. I don't know if this is an issue with the problem I am having. I downloaded the time machine widget as suggested in other posts on this topic, the log is posted below. There are errors about the disc being full and an error writing to the backup log. I don't know why it can't right to the log or what could be wrong. After looking at the logs, it appears that what is shown below just continues to repeat about every two hours (time machine seems to give up after about 2 hours and starts over again with the same result).
I am thinking of erasing the time capsule disc and trying to start over, but would like to figure why this has happened before I erase the disc. I am also worried about erasing my only backups, even if they are three weeks old. Entering time machines still seems to give me all of my older backups like nothing is wrong, but I haven't restored from one so they may not work if I tried.
Any help would or insight into this would be greatly appreciated.

Ordinarily it will. Do you have other data on the drive? If so, it appears that other data has completely filled the drive, so much so that Time Machine can't even start the hidden log it keeps there.

Usually when that happens, the backup crashes.
First, cancel the backup. If it won't cancel after a few moments, see #D6 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html].
Then connect via an Ethernet cable if at all possible. Time Machine needs to do some intensive work, and it will be slow even via Ethernet, but 2-3 times slower via WIFI.
If there's other stuff on the drive, you could copy some of it elsewhere temporary and delete it. You only need to free up 50 MB or so.
But your best bet is to delete your oldest backup(s), then "compact" the sparse bundle they're in, to make some space. See #12 of [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html].
Since it's been several weeks, you may want to delete roughly one old backup for each of those weeks, then "compact" the sparse bundle. If you only delete one, then Time Machine will have to delete more, but it will delete one, dismount the sparse bundle, compact it, then remount it to see if there's enough room. That gets repeated over and over until there's enough space.
Once this is sorted out, if there is other stuff on your TC's internal HD, see #Q3 in [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum).

Time Machine stuck in "Calculating Changes"

I am backing up time machine to a 1 tb Seagate GoFlex Desk. It is formatted to MacOS extended journaled. It works about 80% of the time, but a couple of times a day I check and it is stuck in "calculating changes". The only solution i have found is unplugging it which gives me the message "You need to eject". I just reinstalled the os hoping that would take care of it, but no dice. I did try logging out to see if that reset it, and it got stuck at my blank desktop background. But when I unplugged the harddrive, it finished logging out. Anyone have any solutions to these very annoying problems?

Hi jtupnsmoke - I have the exact same problems and am also using the Seagate 1TB Flex Drive- have had unplug the drive and have had the improperly ejecting the drive message, etc. I'm stuck in calculating changes once again. It is the only problem I've had that I wasn't able to fix with help from all of the great people on these boards. I'm about ready to plug in my old OWC Neptune external drive and see if it makes a difference.

Stuck on "calculating changes"

Hi there,
I have time machine set up on an external USB drive and I'm stuck on "calculating changes" when I try to make a backup. It was normal until a couple of days ago, when the drive suddenly disconnected from the Imac in the middle of a backup (I think it was due to an oscilation on the power supply or something like that, not physically disconnected). Ever since then, I'm not able to make new back ups.
I already ran a disk test (on disk utility) and it is normal. I also tried to remove and add the disk on the time machine preferences, but still nothing.
I got a log from Time Machine Buddy:
*Starting standard backup*
*Backing up to: /Volumes/Backup e Dados/Backups.backupdb*
*Event store UUIDs don't match for volume: Macintosh HD*
*Waiting for index to be ready (100)*

*Waiting for index to be ready (100)*
*Waiting for index to be ready (101)*

Any ideas on how to fix this?
Thanks,

Do you mean you ran +*Repair Disk+* (not permissions) on the TM drive? If not, try that.

That's normal after a disconnection; it just means Time Machine isn't sure it got everything the last time.

These mean Time Machine is indexing your backups (because of the abnormal disconnection). It should complete that and proceed with the backup, which will probably take a lot longer than usual.
If Disk Utility didn't find a problem with the file system, the drive itself may be damaged. How old is it?
If you haven't yet, try cancelling the backup, ejecting, disconnecting and powering it off for several minutes. Then Restart your Mac and try again. Make sure all connections are snug and secure; try different ports, cables, and combinations of the two (a plug that works fine in one port may not make good contact in another).

Stuck on calculating changes - Waiting for index to be ready

I've got a Time Machine which had my disk properly backed up (~500 Gigs). Then, I used Entourage Time Machine to save my email database to a set of local XML files (tens of thousands of new files). Since then, it's stuck on Calculating Changes; I tried stopping it, removing the .plist file, stopping/restarting the service, etc. I restarted it again and now it's once again on Calculating Changes for 12 hours now. Time Machine Buddy says "Waiting for index to be ready". Could it possibly really be doing what it needs to do or is it stuck somehow and is there anything else I can do??
thanks in advance,
Mike

did that - repaired the disk, no problems found.
Uh, you need to check your internal, too, if you didn't. It's probably ok, but it's best to be sure. Then Restart your Mac.

A few of those may not be a problem, especially after a failed backup. The backups have to be indexed for TM to work right.
why isn't the index ready - could it have anything to do with Spotlight (which is also going like mad, but at least now gives a time estimate) - is that the index it's talking about??
Perhaps. Both Spotlight and Time Machine use the mds process to index.

Ok, so I disabled Spotlight, deleted all the .Spotlight files on all volumes, and restarted Time Machine having excluded the Entourage database and 56 Gigs worth of .xml files of individual messages.

The deep traversal completed. It found about 20 GB to back up (plus 20% for workspace -- the "padding" in the message).
Error: Flushing index to disk returned an error: 0
That's another problem writing the index to the TM drive.
Try a +*Repair Disk+* on it again, and make sure all connections are snug and secure, and try the backup again.
If this continues, it's beginning to look like a problem with the disk or connections. Try different ports, cables, and combinations of the two -- cables do deteriorate, and a plug that works fine in one port may not make good contact in another one.

In Lion 10.7.x I cannot disable the Lock documents for 2 weeks in Time Machine! Thus it prevents to change anything else like the system preferences or other settings. How I can disable it?

Hello, In Lion 10.7.x I cannot disable the Lock documents for 2 weeks in Time Machine! Thus it prevents to change anything else like the system preferences or other settings. All is locked. How I can disable it?

Do you mean the check box isn't enabled?
Or you remove the check but it doesn't "stick"?
Or you remove the box but documents are stil getting locked?
That setting doesn't apply to other things in System Preferences, just apps that support AutoSave and Versions. If you're having a problem with System Prefs, please clarify exactly what.

i upgraded my imac hard drive to a 2tb drive. how do i use time machine to get my computer back to normal?

Thank you. I followed the faq#14 (using setup wizard from the osx install disk). Everything went just as planned until I woke up this morning and noticed there was no progress on the "transferring documents" meter. It stopped about 1/4 of the way. I can hear the computer working and the bar is somewhat animated like it is advancing but it's not.
Should I cancel and restart or should I wait it out? It already been about 13 hours since I started the process. Do you think it is my time machine or my iMac? Maybe the time machine file is corrupt or something.
Anyway, any help is appreciated. Thanks.

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."

Then repair the backup/TM drive.

hello,
I had the same issue. This is what I was told to do.
iWork has to be removed completely to be effective when re-installing, you must use an application removal tool to do this or it wont remove every Keynote file.
Appcleaner   will do this and its free.
The following procedure has helped solve many issues with Keynote:
1 Close Keynote then use Appcleaner
2 Empty the Trash
3 Shut down the Mac, then restart and press the shift key immediately after the startup sound, then release shift when the Apple logo appears
          allow the Mac to boot up to the desktop, it will take longer then usual as the hard drive is being repaired
4 restart the Mac
5 Reinstall iWork
6 Repair permissions:
          Applications > Utilities > Disk Utility > First Aid:   click on your system disc in the drive column
          and select Repair Disk Permissions
7 open Keynote and test

I'm on Mountain Lion and have version 6.1 of AirPort utility so there is no button to "Disconnect All Users"and the only other option of "removing and re-selecting the drive via Time Machine Prefs" doesn't work either. So this will work.
Launch Airport Utility and select the TC "Edit" button, then select the Disks tab. Deselect "Enable File Sharing" and click "Update". The TC will reboot then follow the same procedure and reselect "Enable File Sharing" and click "Update". After TC reboots again you'll be up and running. Not the neatest way to do it but saves having to unplug the TC which risks disk damage and the whole procedure takes less than a minute.The "Enable File Sharing" button seems to have replaced the "Disconnect All Users" button but with the slight disadvantage that it reboots the TC which takes up additional time.

After a full restore from Time Machine, I get "error code -6584" when trying to go into TM.

I took our iMac in, at the direction of Apple, to have the hard drive replaced. When we got it back, I restored from Time Machine (on Time Capsule). One file on the desktop, a spreadsheet file, has reverted to a version five months old, with the loss of considerable data, so I don't know which files I can now trust. Also, when I try to go into Time Machine, I get "error code -6584" and am unable to access my backups
This is potentially very very bad. What can I do?

Solved:
sudo chflags 0 /Volumes/"FCP Time Machine BU"
sudo chown 0:80 /Volumes/"FCP Time Machine BU"
sudo chmod 775 /Volumes/"FCP Time Machine BU"
sudo chmod -N /Volumes/"FCP Time Machine BU"
