Time Machine stuck in a new and different way

Time Machine is stuck in a new way. "dtruss -e -p <pid>" shows it in a loop doing nothing but this:
   1032 __semwait_signal(0xC03, 0x0, 0x1)

I killed it, trashed the .inProgress backup, and started it up again and it has been like this for two more days.

Any ideas?

How can I get Time Machine to only backup new and changed files?

Time machine is backing up more than just new and changed files and is filling up my back up disk too fast. How can I change it so that it will only back up the new or changed files instead of the whole drive? I used to have my backups go back months, but now it is backing up only a couple days back, since there is no room left on my back up hard drive. Each back up is like 400 gigs, instead of just the amount of the changed or new files.
Thanks for any ideas or help!

Thank you Eric! I did go look at this info and tried to do a full reset of TM and I am still getting full backups of my HD instead of just new/changed files. The weird thing is that I have 9 BU's from over the last 2 days and they all seem to be around 415 gigs and my backup HD is only 750 gigs! I don't get it. It shows that I have around 75 gigs of free space on that 750 gig drive. It doesn't make sense.
So I am having the same problems even after doing the full reset of TM. I am using Mavericks 10.9.5 which they don't talk about in this info.
Does anyone have any further ideas on this? I don't understand how I could possibly have that many full BU's on my HD that is only 750 gigs.
Thank you,
kt

Time Machine stuck on "preparing backup" and "Indexing Backup" after forced restart and install from Lion

Hello!
I have been using Time Machine on the Time Capsule for over a month now and no problems. However when I was installing Lion it had to restart. I did not see that Time Machine was going at the time when I pushed restart until it was too late.
Now Time Machine seems to be stuck on "Preparing Backup" and "Indexing Backups". It has been nearly 20-30 minutes for Indexing and I wonder if I corrupted something or something else. If there a way I can solve this problem? Thanks!

I had this same problem, this is going to sound ridiculous but this is what I finally did. I wiped my backup, crazy right?
It's there for when your hard drive crashes, so it's not like you are going to miss much if you wipe it. Tell it to stop backing up, go to disk utility, click your external and then erase it. Go back to time machine settings and reselect it as your backup drive. It will do an initial back up again and you are good to go.
Hope this helps.

I have 2 auxillary disk drives for my MacBokk Pro. Time Machine uses one for backup and I use the other for storage, but I am unable to create a new folder or drag and drop files or folders to the aux drive.

I am unable to create a new folder on either of my auxillary disk drives. I can access the files and folders that were there when I transferred one of the drives from a PC. Time machine uses one for backup and I want to use the other to store photos which are large files. An help would be appreciated.

Thanks for the reply. If I reformat the drive will I be able to access the files on it from the MAC. I do not share the drive with a PC. The files were originally created on a PC which I no longer use. I do want to continue to access the files put there by the PC. I would like to not have to copy them over to the MAC hard drive just to use them. The second aux drive is new and works fine because it was formatted by the MAC. I can drag and drop files there and work with just as if they were on the internal drive.

My Fantom backup drive is failing. I want to copy the time machine contents to a new backup drive and continue on as if nothing has happened. Can I do this and if so how? I have intel iMac running Mountain Lion. Fantom Drive via Firewire 800.

My Fantom backup drive is failing and I have to send it in for warranty repair. Before I do that I want to copy the time machine contents to a new drive and then use it for the backup, continuing on as if nothing had gone wrong with the first drive. Can I do this? Is it as simple as duplicating the first drive and replacing it with the second? New drive arrives Tuesday PM and both drives have dual firewire 800 ports.

I have used the Disk Utility to verify the contents of the backup drive so I don't think I have any corrupt files. The drive just takes a minute or so to spin up to speed. If I turn it off and then back on, it beeps at me for a few seconds and then starts it's slow process of trying to spin. I think it's a power problem not a data problem. I have my fingers crossed that it holds on until Tuesday PM when the new drive arrives. I'm thinking that my two options are to duplicate the bad drive or partition the new drive and put the old backups on one partition and start afresh on the second partition. Any input?
And thanks to both of you for the valuable information so far!

HT201250 Time Machine migrate to a new Macbook Pro and keeping Logic plugins

So, I'm getting a new macbook pro (the latest 15" with the highest spec) and I'm looking to transfer everything using Time Machine, so that it's as if I'm still using the same machine. I use Logic 9 and I have hundreds of expensive plugins and I want to be sure that they will transfer across and I won't need to buy any of them again. I appreciate that some may have compatabiity issues, but that aside, will everything transfer as if I'm using the same machine and it will all be exactly the same?

Hello there, micchaelfrombarnes.
As per the article you were referred to us from, Time Machine should be able to restore your new MacBook to be just like your current one:
Mac Basics: Time Machine backs up your Mac
http://support.apple.com/kb/HT1427
Time Machine automatically backs up your entire Mac, including system files, applications, accounts, preferences, email messages, music, photos, movies, and documents.
Additionally:
Migrating a Time Machine backup to a new Mac
When you get a new Mac, you can transfer all of your applications, files, settings, and other information from a Time Machine backup you've already made. When you start up your new Mac for the first time, the Setup Assistant asks you if you would like to restore from backup. If you've already set up your new Mac, you can use theMigration Assistant (located in Applications/Utilities) to do the same thing.
After Migration Assistant completes the transfer and you select your existing Time Machine backup drive, you will be prompted with "Inherit Backup History". Once selected you will be able to continue to use your existing Time Machine backup on your new Mac.
For a more detailed instruction on how to migrate the data from your Time Machine backup, refer to this article:
OS X: How to migrate data from another Mac using Mavericks
http://support.apple.com/kb/HT5872
Thanks for reaching out to Apple Support Communities.
Cheers,

Why do I get this message every time I travel with my laptop and then return home: To improve reliability, Time Machine must create a new backup for you.

Why do I get this message every time I travel with my laptop and then return home: "To improve reliability, Time Machine must create a new backup for you."
I get this on my new MacBook Air, but never got it on my old MacBook Pro.
Thanks!

no archive/ backup is perfect, HD clones can be set to make incremental additions, same as time machine however, though they are more time involved in doing so.
See the + and - of all data backup/ archives below and "spread it around".... or the "dont put your eggs all in one basket" philosophy.

Data Storage Platforms; their Drawbacks & Advantages
#1. Time Machine / Time Capsule
Drawbacks:
1. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.
2. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.
3. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. This extra link of failure in placing software between your data and its recovery is a point of risk and failure. A HD clone is not subject to these errors.
4. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.
5. Time Machine does not keep endless copies of changed or deleted data, and you are often not notified when it deletes them; likewise you may accidently delete files off your computer and this accident is mirrored on TM.
6. Restoring from TM is quite time intensive.
7. TM is a backup and not a data archive, and therefore by definition a low-level security of vital/important data.
8. TM working premise is a “black box” backup of OS, APPS, settings, and vital data that nearly 100% of users never verify until an emergency hits or their computers internal SSD or HD that is corrupt or dead and this is an extremely bad working premise on vital data.
9. Given that data created and stored is growing exponentially, the fact that TM operates as a “store-it-all” backup nexus makes TM inherently incapable to easily backup massive amounts of data, nor is doing so a good idea.
10. TM working premise is a backup of a users system and active working data, and NOT massive amounts of static data, yet most users never take this into consideration, making TM a high-risk locus of data “bloat”.
11. In the case of Time Capsule, wifi data storage is a less than ideal premise given possible wireless data corruption.
12. TM like all HD-based data is subject to ferromagnetic and mechanical failure.
13. *Level-1 security of your vital data.
Advantages:
1. TM is very easy to use either in automatic mode or in 1-click backups.
2. TM is a perfect novice level simplex backup single-layer security save against internal HD failure or corruption.
3. TM can easily provide a seamless no-gap policy of active data that is often not easily capable in HD clones or HD archives (only if the user is lazy is making data saves).
#2. HD archives
Drawbacks:
1. Like all HD-based data is subject to ferromagnetic and mechanical failure.
2. Unless the user ritually copies working active data to HD external archives, then there is a time-gap of potential missing data; as such users must be proactive in archiving data that is being worked on or recently saved or created.
Advantages:
1. Fills the gap left in a week or 2-week-old HD clone, as an example.
2. Simplex no-software data storage that is isolated and autonomous from the computer (in most cases).
3. HD archives are the best idealized storage source for storing huge and multi-terabytes of data.
4. Best-idealized 1st platform redundancy for data protection.
5. *Perfect primary tier and level-2 security of your vital data.
#3. HD clones (see below for full advantages / drawbacks)
Drawbacks:
1. HD clones can be incrementally updated to hourly or daily, however this is time consuming and HD clones are, often, a week or more old, in which case data between today and the most fresh HD clone can and would be lost (however this gap is filled by use of HD archives listed above or by a TM backup).
2. Like all HD-based data is subject to ferromagnetic and mechanical failure.
Advantages:
1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
3. HD clones are unconnected and isolated from recent corruption.
4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD).
7. *Level-2 security of your vital data.
HD cloning software options:
1. SuperDuper HD cloning software APP (free)
2. Carbon Copy Cloner APP (will copy the recovery partition as well)
3. Disk utility HD bootable clone.
#4. Online archives
Drawbacks:
1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
Advantages:
1. In case of house fire, etc. your data is safe.
2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
5. *Level-1.5 security of your vital data.
#5. DVD professional archival media
Drawbacks:
1. DVD single-layer disks are limited to 4.7Gigabytes of data.
2. DVD media are, given rough handling, prone to scratches and light-degradation if not stored correctly.
Advantages:
1. Archival DVD professional blank media is rated for in excess of 100+ years.
2. DVD is not subject to mechanical breakdown.
3. DVD archival media is not subject to ferromagnetic degradation.
4. DVD archival media correctly sleeved and stored is currently a supreme storage method of archiving vital data.
5. DVD media is once written and therefore free of data corruption if the write is correct.
6. DVD media is the perfect ideal for “freezing” and isolating old copies of data for reference in case newer generations of data become corrupted and an older copy is needed to revert to.
7. Best-idealized 4th platform redundancy for data protection.
8. *Level-3 (highest) security of your vital data.
[*Level-4 data security under development as once-written metallic plates and synthetic sapphire and likewise ultra-long-term data storage]
#6. Cloud based storage
Drawbacks:
1. Cloud storage can only be quasi-possessed.
2. No genuine true security and privacy of data.
3. Should never be considered for vital data storage or especially long-term.
4. *Level-0 security of your vital data.
Advantages:
1. Quick, easy and cheap storage location for simplex files for transfer to keep on hand and yet off the computer.
2. Easy source for small-file data sharing.

Failed resting from Time Machine backup on a new HD

Is anyone here dealing with a problem of full restoration from time machine on a brand new HD on MacBook Pro?
I follow the full procedure:
- did a complete backup of old HD with TM
- started the PC with http://support.apple.com/kb/DL1433 Lion recovery Disk Assistant
- formatted HD with disk tool
- launched the restoration from time machine
- restoration move very very slowly and @ certain point of time crash (after some % of process)
I did several attemps doing in different way the backup and restore but no way.
I'm gonna do a full image and restore the image. Not good for a promising backup system!!
Some suggestions?
thanks Matteo.

Please visit Pondini's Time Machine FAQ for help with all things Time Machine.
You will find that Mountain Lion stores an invisible copy of the Recovery HD. You can boot from your Time Machine backup drive by restarting with OPTION boot:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the "OPTION" key.
3. Release the key when the boot manager appears.
4. Select the disk icon for your Time Machine backup drive.
5. Click on the arrow button below the icon.
Your computer should boot into the Recovery HD. You will be presented with a main window of options. Select the option to restore from a Time Machine backup then click on the Continue button.

Going on using existing time machine backup in a new network

Hello community,
I just set up a wireless network with my new time capsule. As I used to do my time machine backups on an external USB hard drive (Intenso), I connected it to the TC for extending my network space and going on using this volume as my backup-volume.
Unfortunately Time Machine doesn't recognize the Intenso drive as my old backup volume although I did nothing else than plugging it into the TC instead of my Macbook. My Macbook is the same, the OS is the same, the backup drive is the same. Only the port is a different one. I cant understand that Time Machine doesn't recognize my backup only because its now in the wireless network instead of plugged to the USB port.
Is there anything I can do to make time machine going on using my old backup in the network?
Thanks a lot.
Fabian

Unfortunately Time Machine doesn't recognize the Intenso drive as my old backup volume although I did nothing else than plugging it into the TC instead of my Macbook.
Nothing is the same. There is a huge difference here depending on whether a hard drive is connected directly to a Mac......in which case it is a "local" drive.....or if a drive is connected to a device like the Time Capsule.....which is a "network" device.
In other words, if you connect a drive to the USB port on the Time Capsule, the drive becomes a "network" drive.
Time Machine stores backups differently depending on whether the drive is attached as a "local" drive or whether the drive will be connected as a "network" drive. On a "network" drive, Time Machine backups are stored in a special type of container called a sparsebundle.
You can set up Time Machine to back up to the drive connected to the Time Capsule.......but Time Machine will not continue to back up to the same file that was being used when the drive was connected directly to your Mac. Instead, Time Machine will make a new, complete backup and then continue to back up incrementally once the first "master" back up is done.
Obviously, this will require quite a bit more space on the hard drive, since you will have two sets of backups on the drive.
If you want to "see" the backups that were made when the drive was connected directly to your Mac, you will need to connect the drive directly to your Mac and access them that way.

Time Machine stuck in Preparing Data Mode

In the past two days my time Machine has not made a successful back up. It seems to be stuck in "preparing data" and will stay like this all day. Even when I click the time machine preferences and stop it, it never changes. Does anyone have any solutions to this or has experienced it.Any suggestions would be greatly appreciated.
Thanks!!

Judith,
The following might contain an explanation for what you are experiencing.
*_Time Machine May Report "Preparing..." For a Long Time_*
First, it’s good to determine WHY Time Machine is "Preparing..." for an extended period of time. Examining the Console logs during this event can reveal what is actually going on behind the scenes. It may be “Preparing…” for a genuinely good reason. How long is 'too long' to wait for Time Machine to finish "Preparing..."? Some times, "Preparing..." is required to perform the normal housekeeping that Time Machine does periodically. Other times, it really is "stuck" and never proceeds after more than 24 hours.
*”Deep Traversal” (Recent Crash / Forced Restart / System Update / Extended Period Between Backups)*
According to the following KB article it can sometimes take quite a long time if Time Machine begins a “deep traversal” and has to compare data inventories. This may apply to your situation, particularly if many Gigs of data are involved. [http://support.apple.com/kb/TS1516]
You see, Time Machine *+does not+* ordinarily perform file-by-file comparisons to determine what has changed and thus determine what needs to be backed up. Rather, Time Machine relies on FSEvents notifications. This is a log that the system uses to keep track of changes to directories. Rather than scan tens of thousands of files for changes each time, Time Machine simply looks at this log and narrows its’ scan to only the directories that have experienced changes since the last backup. Otherwise, Time Machine would have to be running constantly just to catch every change on its own and thus eat up precious CPU.
Every event that FSEvents records has its’ own ID which includes a time stamp. At the end of every backup, Time Machine stores the last event ID that it processes. When the next backup is initiated, Time Machine looks at this stored ID and determines that it only needs to backup events that have occurred after the time stamp on this last event ID.
If, due to a system crash, power failure, forced restart, or some other major system event, Time Machine cannot find this last event ID in the system logs then it will consider the FSEvents log “untrustable” and it will go into what’s called “deep traversal”. The Console logs may report +“Event store UUIDs don't match”.+ In this event, Time Machine will by-pass the system log entirely and perform its’ own file-by-file comparison to determine what has changed since its’ last backup. Obviously, if tens or hundreds of Gigs are involved, then this process can take quite some time and should be allowed to proceed.
Additionally, it appears that if Time Machine has to go back too far to find the last event ID, then it will give up and simply go into “deep traversal” and do the file-by-file scan on its’ own. This can occur if Time Machine has not been able to perform its’ hourly backups for some time, as is the case for users who only backup once a week or so. This is also the case with major Mac OS system updates that change thousands of files at one time. There are simply too many events logged by the system for Time Machine to bother looking for the last known event ID.
*Consolidation / “Thinning”*
At the beginning, when Time Machine is first used, incremental backups are relatively quick events. But as time goes on, and backup files grow, Time Machine requires time to perform house-keeping on the backed up data. This maintenance is referred to in the Console logs as "thinning". The larger the backup files become, the more time Time Machine requires.
To prevent the backup drive from filling up too fast, Time Machine will periodically consolidate, or 'thin', backups to free up space for new data. After a certain period of time, each hourly backup becomes "expired". This occurs about 24-48 hours after the hourly backup took place. At that point Time Machine begins consolidating, or "thinning", all the hourly backups of a given day into one daily backup. Then, after about a month all daily backups for a given week “expire” and are consolidated into a single weekly backup.
Obviously, since the Time Machine process (backupd) does not run continuously, it has to do this "thinning" during routine backups. That is where "Preparing Backup..." and "Finishing Backup..." come in. It is during these initial and closing phases of a backup that "thinning" occurs. As a result, while not every backup will be accompanied by extended periods of "Preparing..." and "Finishing...", periodically Time Machine will require extra time to perform these space-saving consolidations.
*Anti-Virus Software*
Running anti-virus software can interfere with the backup process. Either disable it altogether, or try the suggestion outlined here, “If you use third-party anti-virus scanning software and have issues, make sure your Time Machine back up folder (Backups.backupdb on the Time Machine disk) is excluded from virus scanning.” (http://support.apple.com/kb/TS1516)
*Software Updates* #
Installing new software, upgrading existing software, or updating Mac OS X system software can create major changes in the structure of your Macs directories. Time Machine will backup every file that has changed since the installation.
After an OS update (like 10.5.5) Time Machine realizes the system no longer matches what it looked like during the previous backup. So it has determined that it's earlier catalogue of what-should-be-where is “untrustable”. So it is going to go item-by-item comparing the before and after of your system.
*Spotlight Keeps Indexing Backup Drive* #
It may be that Time Machine can’t proceed or complete a backup due to Spotlight indexing. During this period, take a look at the Spotlight icon in the upper right corner of your screen. Is there a tiny dot pulsating in the center of the spyglass? Click on the icon. Is there a progress bar displayed? Generally, Spotlight indexing is a good thing. If it has only been a couple of hours then, stop the backup, turn Time Machine OFF, and let the indexing continue.
However, at times Spotlight may hang and never progress after many hours, preventing further backups from taking place.
Go to System Preferences --> Time Machine.
Using the slider on the left, turn OFF Time Machine backups for now.
Next, click “Show All” in the toolbar.
Select the Spotlight Preferences.
Click the Privacy Tab.
First, drag your Macs’ internal hard disk from the desktop to the Privacy list.
Wait 10 seconds, then highlight the Macs’ hard disk in the list and click the tiny “-” button at the bottom to remove it from the list.
Spotlight will initiate a reindex of the hard disk. If you click on the Spotlight menu icon you may see the message:
+“Spotlight helps you quickly find things on your computer. Spotlight will be available as soon as the contents of your computer have been indexed.”+
...and a progress bar will indicate the time remaining.
Once completed, drag your Time Machine backup disk into the Privacy list of the Spotlight Preferences.
Wait 10 seconds, then highlight the Time Machine backup disk in the list and click the tiny “-” button at the bottom to remove it from the list.
Spotlight will now initiate a reindex of the hard disk.
Once completed, if you have any other hard disks attached to your Mac that are also being backed using Time Machine, then force a reindex as well using the procedure outlined above.
Then turn Time Machine back ON and initiate a backup.
*Run Away System Process*
It’s possible that Time Machine is stuck “Preparing…” because another process is monopolizing your Macs’ CPU. Launch Activity Monitor and sort the items by “CPU”. Is there a process that is at or near 100% that might be preventing the backupd process from moving forward?
One poster stated, “I took it to my local Genius Bar and they found a Syslogd daemon running, taking up 100% of my CPU….This resulted in the "Preparing..." mode running forever.” [http://discussions.apple.com/thread.jspa?threadID=1755600&tstart=15]
You may be able use Activity Monitor to “kill” the offending process. Or you may be able to resolve it simply by rebooting your Mac. Then try backing up again.
*Verify/Repair Mac Hard Disk & Permissions*
It may be that your Macs’ internal hard disk has so many file/directory issues that Time Machine simply has trouble making sense of it. Some users have had success using Disk Utility on their Macs’ hard drive.
Launch Disk Utility and click “Repair Disk Permissions”.
Once complete, attempt a backup.
If Time Machine appears to hang at “Preparing…” again, then do the following:
Insert your Macs’ original install DVD and reboot holding down the “C” key.
At the Welcome screen go up to the “Utilities” menu and select Disk Utility.
Select your Macs’ hard disk on the left and click “Verify Disk” on the right.
If problems are found click “Repair Disk”.
Reboot to your normal desktop and try backing up again.
*For Time Capsule Users* #
If, though, none of the options above have helped and it has been 12 hours or more of “Preparing…”, then the Time Capsule may need to be restarted.
Stop the backup from the Time Machine menu. (Give if a few minutes while it says “Stopping backup…”)
When the Time Machine icon stops spinning, unplug the TC from the wall outlet.
Wait 10-15 seconds.
Re-plug it in again.
After it has restarted (30-60 seconds), attempt another backup.
Time Machine will report “Preparing…” again, but it shouldn’t be lasting more than a couple of hours.
Let us know if any of the above was helpful in resolving your issue.
Cheers!

Time Machine stuck in "preparing" endlessly.

I have been able to successfully back up my MacBook Pro twice in the past two months using Time Machine, but both times I had to monkey with it, and I'm not even sure what exactly I did to make it work.
Today I've tried several times to back up my machine, but it seems to get stuck "preparing" for hours.
I don't keep Time Machine plugged into my laptop because I need that USB for my printer. Rather, I periodically plug my Sea Gate FreeAgent external drive in and attempt to manually back up. But it never just works without a lot of clicking around.
What am I doing wrong??? How can I get it to work??
Thanks so much!

xtine,
Your situation is explained in the first section of the info below:
*_Time Machine May Report "Preparing..." For a Long Time_*
Consider these factors regarding an extended period of "Preparing...". Consider each topic separately and do not attempt to act on all of them at once.
*Recent Crash or Other Major System Event* (Deep Traversal)
The reasons for this process are described in an article by George Schreyer. “During the preparation step it checks the FSEvents log for consistency. If it determines that something isn't quite right it has to rescan the whole disk. This can take quite awhile. A full rescan is always triggered by a crash, an unplanned shut down event or by booting from some other bootable disk between backups…. After a crash, Time Machine must scan the whole disk to determine what it has to do because it cannot trust the information that it left behind. Connected via an Ethernet connection, this phase would typically take 20 minutes on an older PowerBook. Being connected wirelessly stretches this phase out to over 3 hours.” [http://www.girr.org/mac_stuff/backups.html]
According to the following KB article it can sometimes take a very long time if Time Machine begins this “deep traversal” and has to compare data inventories. This may apply to your situation, particularly if many Gigs of data are involved. (http://support.apple.com/kb/TS1516) Additionally, if Time Machine has not been able to perform its’ hourly backups for 24 hours or more, then it will perform a “deep traversal” once backups are renewed. This is the case for users who only backup once a week or so.
*Anti-Virus Software*
Running anti-virus software can interfere with the backup process. Either disable it altogether, or try the suggestion outlined here, “If you use third-party anti-virus scanning software and have issues, make sure your Time Machine back up folder (Backups.backupdb on the Time Machine disk) is excluded from virus scanning.” (http://support.apple.com/kb/TS1516)
*Software Updates* #
Installing new software, upgrading existing software, or updating Mac OS X system software can create major changes in the structure of your Macs directories. Time Machine will backup every file that has changed since the installation.
If you take a look at the Console logs Time Machine may be reporting that your backups need "deep traversal". That's fine. Time Machine knows what is wrong and how to fix it. If you have a great deal of data, it may take quite awhile.
After an OS update (like 10.5.5) Time Machine realizes the system no longer matches what it looked like during the previous backup. So it has determined that it's earlier catalogue of what-should-be-where is 'untrustable'. So it is going to go item-by-item comparing the before and after of your system. If you have just performed an OS Update then Time Machine knows what it's doing - let it do it!
*Spotlight Keeps Indexing Backup Drive* #
It may be that Time Machine can’t proceed or complete a backup due to a Spotlight indexing error. During this period, take a look at the Spotlight icon in the upper right corner of your screen. Is there a tiny dot pulsating in the center of the spyglass? Click on the icon. Is there a progress bar displayed? Generally, Spotlight indexing is a good thing. If it has only been a couple of hours then let the process contiune.
However, at times it may hang and never progress after many hours, preventing further backups from taking place.
Go to System Prefs --> Spotlight --> Privacy Tab.
Drag your Time Machine disk into the window. It should now be among the items to exclude from indexing.
Now quit System Prefs.
Reboot your Mac.
Reopen System Prefs and remove ("-") the Time Machine disk from the window.
Now initiate a backup.
This should clear out Spotlights cache. Naturally, Spotlight should begin indexing again (maybe even for a few hours depending on how much data there is), but it should eventually stop.
*Reboot Time Capsule* #
If, though, none of the options above have helped and it has been 12 hours or more of “Preparing…”, then the Time Capsule may need to be restarted.
Stop the backup from the Time Machine menu. (Give if a few minutes while it says “Stopping backup…”)
When the Time Machine icon stops spinning, unplug the TC from the wall outlet.
Wait 10-15 seconds.
Re-plug it in again.
After it has restarted (30-60 seconds), attempt another backup.
Time Machine will report “Preparing…” again, but it shouldn’t be lasting more than a couple of hours.
Let us know if any of the suggestions above helped in your case.
Cheers!

Using Time Machine Backup Drive with NEW Macbook Pro

I just got a new Macbook Pro. I migrated from my old MacBook Pro. Now I want to use my Time Machine Disk with this new machine.
When I connect the external drive, and select back up now, it says there is not enough space (due to the fact this is a new machine and it wants to backup the entire thing)
Also, when I go into the TimeMachine, it doesn't show me anything past today. . . all of my backups are not displayed over the past year. . .
How do I make it so that the external drive displays all my old backups. . . ??
Thank you for your help.

Turn off TM or set the backup drive to null. Rename your computer in Sharing preferences to the same computer name of your old computer. Turn TM back on and reselect the backup drive. TM will behave as you expect. Of course if the file dates on the new machine are all changed since the migration, then TM will correctly assume that they require backing up. You will then find that there will not be sufficient space on the drive for the new backups. If this occurs then you should simply erase the backup drive and start your TM backup anew.

HT5096 I need to transfer a time machine backup to a new drive. It keeps failing.

I have a 2TB Time Capsule that I was using for Time Machine for both a MacBook and an iMac. The iMac sparse bundle became corrupted earlier this spring and I was unable to delete it, so I need to reformat the TC. First, however, I need to move the TM sparse bundle for the MacBook to a new drive that I have set up just for TM for the MacBook. After reformatting, I plan to only use the TC for the iMac. I tried moving the sparse bundle tonight to the new drive, following directions listed in several places on this site and on Pondini's site. However, it failed. I am going to guess that it failed b/c I was not hooked up to the TC via ethernet. (I was on WIFI). The new backup drive is a 2TB external that was plugged directly to the MacBook. So, now I have connected them via ethernet. I am again reparing the TC volume using Disk Utility, just to make sure all permissions, etc, are ok before moving. Will I be able to move this file to the new drive easily, or should I plug the new drive directly to the Time Capsule and move it that way (while MacBook is connected via Ethernet).
Alternativey, is there a way to just archive that sparse bundle for the MacBook before I erase the drive?
FYI I am still running Snow Leopard on these machines, but trying to clean up the time machine backups today before installing Lion and moving to iCloud, so time is of the utmost importance here.
Thanks so much!
Kat

OK, this has now failed twice. I repaired the drive using DU and there were no problems (even though it took 2 hours to go thru everything to verify). Right now, the MacBook is connected via Ethernet to the TC. The new TM drive (WD 3TB external, USB 3.0/2.0) is attached to the MacBook via USB. I really need to keep this TM backup for the MacBook and also need to erase the TC. How can I accmplish both? I thought that there was a way to archive a TM sparse bundle?

Time Machine stuck in a new and different way
