Time machine backups have slowed considerably since my installation of Mavericks -- why?

Ever since installation of Mavericks, time machine backups have slowed to a crawl. The message preparing backup used to to take 10 seconds to a minute, now it takes 5 minutes. The status of the backup used to show 10mb's of 80 mb's backed up, and take under 1 minute, now it takes 5 minutes. Finally cleaning up notice, and the time to clean up has increased significantly. My backups go to an external HD (7200rpm) connected vis firewire 800, that has approx 180 gigabytes available of its 1 terrabybyte capacity.

I upgraded to Mountain Lion a few weeks ago. Everything was fine with Time Machine until a few of days ago.
Same problem others described: extremely slow, taking hours to back up just a few MB.
I verified the Time Capsule drive and my Mac hard drive - no problems found.
I then erased the Time Capsule and started Time Machine. It did the full backup in a fairly reasonable amount of time (several hours, but not unexpectedly long).
When it started its first incremental backup, it reverted to the same problem: extremely slow, but it did finish eventually.
I then shut down the Mac and restarted (power cycled) the Time Capsule. Then I started up the Mac and told Time Machine to back up now. It backed up 30+ MB in just a few minutes, so it seems back to normal. We'll see how it goes when the next scheduled backup starts up.
But you might try rebooting the Time Capsule (and your Mac).
By the way, when it was in the middle of the extremely slow backup, I disabled Norton Anti-virus and it didn't seem to speed it up any. But I left it disabled after I rebooted the Time Capsule and had a successful incremental backup, so I'm not sure yet if Norton is a factor.

Time Machine backups have not worked since upgrade to Lion OS X

I get the following error message when trying to use Time Machine - "The backup was not performed because an error occurred whilecopying files to the backup disk. The problem may be temporary. Try again later to back up. Ifthe problem persists, use Disk Utility to repair your backup disk."

Not one of Apple's better messages.
It's having a problem with a particular file, but there's no hint of that.

I have been using a WD Passport with Time Machine on my iMac. Since I upgraded to Mavericks, the backup no longer works. What do I need to do?

I have been using a WD Passport with Time Machine on my iMac. Since I upgraded to Mavericks, the backup no longer works. What do I need to do?
I assume that upgrading the WD SmartWare is irrelevant as it is not being used. Should I upgrade just as a precaution?
One complication is that I have renamed my user since the last time I backed up.

the problem is with the WD Passport drives. I also have one, and since upgrading to 10.9 I can no longer use mine either. See if this solution works for you: https://discussions.apple.com/message/23943103#23943103

Time Machine backup painfully slow all of a sudden

For some reason my time machine backups have become painfully slow for some reason. They were fine earlier today, then IIRC I booted windows, then booted back into OSX to run a backup. Despite there being only 1 or two changes (files added to the system) time machine began "preparing backup" by going through all the files on my HDD! Now, it is backing up, but at the rate of about 5 Kb/s!
Something is wrong. I've tried deleting the progress file in the backup folder and "resetting" TM by deselecting the backup drive and selecting it again. Nothing worked. Why would TM be so slow all of a sudden?
Has anyone any ideas?

That is a bit suspicious, but not necessarily wrong. Something caused it to think about 16 GB had been changed (it adds 20% for the "padding" in the message).
How are you running Windoze? Is it on a separate partition? If you're running it via virtualization software, with the vm file on an OSX disk but excluded from TM, that's a possible explanation.
105384 files in only 7.2mb? I doubt it...something seems fishy
Those counts are nearly always very high, and sometimes crazy high. There's some indication it's counting all the metadata, extended attributes, etc., as separate files.
If in doubt, boot up from your Install disc and do a +*Repair Disk+* on your boot volume. Then reboot normally and run another backup. That should trigger a "deep traversal," where TM will compare everything on your system with it's backups, to be sure it's got everything it should.

Time Machine backups have become very slow

My time machine backups to a USB attached external drive (dedicated to backups) have recently slowed horribly. They are taking timeframes like 30 minutes to even an hour even when nothing has changed on my system. They didn’t do that previously (usually just a couple of minutes for same).
Console ouput below. I see MDS errors. What are those? Are they a concern?
I have run Disk Utility on both my hard drive and the time machine drive and they look okay.

Time Machine Backup EXTREMELY SLOW

I've recently noticed that my Time Machine backups from my Mid 2009 iMac 3.06 to a WD 1tb MYBook take an incredibly long time. For example, an hourly backup where nothing has really changed (350k according to a TM log) takes over 30 minutes. I've been working with applecare and they can't pin it down. I've tried the following and nothing has changed-
- creating a back to a brand new drive
- disabling or deleting every startup program and launch agent
- Created another new user and backed up from there
- Reinstalled OSX to repair Time Machine
- Created a new boot partition on my HD and installed OSX
- I used the same backup disc on my laptop and it worked fine
The strange thing is hat everything seems to work fine. I ran a verify on my disks. I Boot my original OS disc in and ran the hardware test. NOthing finds a problem. I tried writing large files to and from my HD to see if that could be the problem. MY HD reads and writes quickly (2.5gb copies to/from an external drive in less than 2 minutes).
The only thing that has changed in the past 6 month s is that I updated my ram from 4 to 8GB with Kingston ram. Could it be a bad piece of RAM or my logic board? Everything else seems to be working fine.
Anybody experience anything likes this???

After a hard drive crash, I restored using a Time Machine backup. I figured it would be a good idea to start a fresh Time Machine backup going forward.
Does that mean you erased or reformatted the drive?
If you deleted some or all of the backups via the Finder, cancel the backup, reformat the drive, and start over.
Using a LaCie 500GB Firewire 800 drive (formatted MacOS Extended Journaled), after one hour, only 5GB has been backed up. As my MacBook Pro has 165GB of data, at this rate, it will take almost two days.
Does that hour include the "Preparing" phase? If so, nothing at all was backed-up during that time, so the actual rate is probably much faster.
Also note that the first items backed-up contain a very large number of mostly small files; there are things that must be done for each item, so that sort of backup will be longer than saving a few large files that total the same amount of space. The speed of the backup will increase and decrease during the backup; initial estimates are almost always quite high.
I've removed the Time Machine drive from Spotlight indexing. I have ensured Norton AntiVirus is not running. What else can I do to speed this up? It seems extremely slow by all comparisons I've read.
First, be sure the *Partition Map Scheme* of the LaCie is correct. Use the procedure in item #C1 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.
Also see item #D2 of the same post (you've already done the first two things). Don't try the +*Repair Disk+* while the backup is running, or if you erased or reformatted it before starting this backup.

Time Machine backup size has doubled since updating to iMovie 10.0

So since installing Mavericks and running iMovie 10.0, the size of my Time Machine backup has increased enormously.
It seems clear that Time Machine is backing up my iMovie content twice, that is seeing the old iMovie Events and iMovie Projects folders (which are still present in my Movies folder), and the new iMovie Library package, as separate things even though they cannot be separate as they are not taking up any more space on the disk.
The backup is also taking much longer than usual, though I'm not so worried about that.
Any ideas about the cause or how to fix this?
I'm running Mavericks on a late 2008 MacBook 2.4 GHz Unibody with 8GB RAM and 250GB SSD, backing up to Time Capsule with 2TB hard drive

What I have found so far is that when upgrading to iMovie 10 there is a conversion/duplication process that takes place in order to make your iMovie 9 events compatible with iMovie 10.
They should be nearly identical in size. You can confirm this by right clicking the "iMovie Events" folder (iMovie 9) and the "iMovie Library" package (iMovie 10) and selecting "Get Info" and their respective sizes should be nearly identical. The reason for this is unclear other than you retain the ability to run iMovie 9 which will continue to access the "iMovie Events" folder. iMovie 10 will access the newly created/duplicated "iMovie Library" package. Any new video you add using iMovie 10 will also be stored in the new "iMovie Library".
If you want to see the contents of the "iMovie Library" then right click and select "Show Package Contents". You should see all the folders (events) you created originally in iMovie 9.
At some point I presume you have the option to delete the "iMovie Events" folder if iMovie 9 will no longer be utilized or, better yet, back it up on a separate drive if like me you don't like deleting files until you're absolutely sure you don't need them. Otherwise, from what I have found, you are in fact backing up two sets of files.
For now I had to exclude the "iMovie Events" folder from my Time Machine backup because, like you, my back up nearly doubled in size (videos take up a lot of space) otherwise I got an error message from Time Machine indicating that my external drive did not have enough space for the backup file.

Time Machine backups extremely slow after hard drive replacement

I'm having trouble with Time Machine backups following a hard drive replacement. The Apple Store replaced my MacBook Pro's damaged hard drive three days ago and I successfully restored my system (OSX 10.6.8) using a Time Machine backup. The computer is running fine now, but ever since the repair my Time Machine back-ups take a very long time (>2 hours per backup, versus 30-60 seconds before the repair). I know that the intiial backup of a new computer can take a while but I'm now onto complete backup #10 since the repair and they are not getting quicker. I'm not adding/changing many files or software in between backups. The backups appear to be successful but the external hard drive and computer fan are running nearly constantly, which is concerning (and annoying). Any advice would be appreciated! Thanks.

How many GB does a typical Time Machine backup have?

I have always backep up my Mac to a 500GB external USb hard drive (Seagate, pretty small). It is only filled up about 90 GB so far and its been about a year. (my backups are NOT every day, mostly every two weeks. Every backup is about 2-3 GB and takes 10-15 minutes to complete.
I recently got a Seagate GoFlex Home for wireless backups. However, my first backup says over 200 GB to back up with a wait itme of 7-8 hours. This doesn't seem right... Am I doing something wrong?
I also still haven't found out a way to transfer my old Time Machine Backups to the new GoFlex.
It's backing up right now, and I am continuing to do so until I get a reply that says I shouldn't be. If anyone has an answer, please reply A.S.A.P.
Please Help.
Thanks in advance.

Well I cancelled this backup already, to figure out the prolem first.
Via the Widget, this is what i have so far:

Could the 200 GB backup be because i changed the name of my home folder and now its backing up the permissions changes of all of the files?

Initial Time Machine Backup - Extremely Slow/Freeze

Hello,
I recently switched my external HDDs and began utilizing a different HDD in conjunction with Time Machine. I have used this HDD in the past with Time Machine and never had a problem. The initial backup is proceeding at an extremely slow rate and often freezes - as of writing, it is currently standing at 125.3MB of 1.07TB - About 1,172 days. I have erased and reformatted the drive (Mac OS Extended (Journaled)), tested data transfer rates to it by transferring files myself (normal rate), repaired permissions, verified my disks, tried the initial backup while spotlight was off and have forced a spotlight re-index, allowing it to go to completion before attemtping a backup - however, no solution has thus far worked. I have not made any large changes to my computer since I switched the HDDs either.
Does anybody know what could be causing such a problem and how to fix this? Many thanks for any help,
- Cptbigt

Time Machine Backup is slow (perhaps corrupt?) after Mountain Lion upgrade

Hello!
I managed to download and upgrade from Lion to Mountain Lion yesterday. Before the upgrade, I performed a backup via TM just in case. Now, in Mountain Lion, the backup prepares and begins around 12GB of backups but never gets passed 2MB of data transferred. The TM logo keeps turning, the external HDD is clicking and the activity light is blinking to indicate communication.
I vaguely remember having a slow backup after upgrading from Snow Leopard to Lion, but never *this* slow.
Has anyone else encountered a similar issue or know of any diags I could do? As a prerequisite to this, I have attempted to verify the disk in Disk Utility but it seemed to be taking a long time (around 2 hours without completion) to verify, too.
Thanks =]

I am also experiencing very slow backups since upgrading to ML. You didn't go into specifics on your hardware setup (type of machine, backup drive, etc).
I'm using a MB air (Mid 2011) with a Thunderbolt display. I have a G-Tech 2 gig external drive connected with Firewire 800 through the Thunderbolt display.
My backups had always been pretty quick. Now they can take up to half an hour or longer depending on the amount of data to be processed.
One suggestion for you is to obtain a time machine log viewer. I use "logviewer for time machine" that I got in the Mac App store. I think it is $0.99, but there other apps that are available for free. This is nothing more than a log viewer that you refresh and see each step of your backup including any errors. A lot better than right clicking the spinning circle around the clock in the menu bar for status updates.
I am baffled on why the slowdown. I am think of opening a case with Apple Support.
Take care

Time Machine backup very slow on WD My Book For Mac external HD

I have been using a Western Digital 1 TB external HD (My Book For Mac) to backup my data today for the first time, using their SmartWare software. Everything went smoothly, I backed up 91 GB of data in 2-3 hours.
At the same time, I have also Time Machine activated, which started backing up my files a while ago, but it is crawling at 8 MB per minute. A quick calculation tells me it will take 180 hours to back up 90 GB (?).
I have 2 questions:
1. Are SmartWare and TimeMachine supposed to be run exclusive of each other?
2. If I just ran TimeMachine, why is it so slow? I use a USB 2.0 connection that worked fine for the My Book's own software.
Thanks for your help!

You should first repartition and format the drive. Most likely it is setup for use on Windows. Try this:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Do not use the WD software. If it's you wish to create a bootable backup of your drive as well as keep a TM backup, then you should create two partitions on the drive. One for your non-TM backup and one for TM. For the bootable backup use third-party software such as SuperDuper!, Carbon Copy Cloner, or SilverKeeper - Download at VersionTracker or MacUpdate.
Note that many WD drive systems cannot be used for bootable backups. You can find information related to this at the WD web site.

Why is Entering Time Machine Backup SO SLOW ???

I have been using Time Machine (TM) for almost 2 years and when I enter TM - its is SLOW when I go back the timeline. I have the email window open when entering TM and it is taking minutes to fill in only 50 or so emails (I know I have 1000's).
Any suggestions to help this????
I have an external hardrive for TM connected to Time capsule.

60 seconds !!!
I solved it!
What I did:
I interrupted a running incremental backup after 20 minutes by switching off Time Machine in the control panel. In the log the message was:
     Stopping backupd to allow ejection of backup destination disk!
Then I rebooted the iMac from the Snow Leopard DVD and repaired the SSD and the FireWire Drive. In both cases no failures could be found.
Then I restarted the iMac from its internal SSD and waited until Time Machine started again (after one hour). Now there was something new in the log:
              Event store UUIDs don't match for volume: Speedy HD
              Node requires deep traversal:/ reason:must scan subdirs|new event db|
This backup took just 12 Minutes and was much faster than the previous incremental backups which took 30..45 minutes.
Now I tried the ultimate thing: I ordered Time Machine to make a new incremental backup. See what happens:
30.06.11 21:10:23 Starting standard backup
30.06.11 21:10:23 Backing up to: /Volumes/Archiv 1/Backups.backupdb
30.06.11 21:10:32 No pre-backup thinning needed: 1.83 GB requested (including padding), 911.84 GB available
30.06.11 21:11:03 Copied 9117 files (647.1 MB) from volume Speedy HD.
30.06.11 21:11:08 Copied 9365 files (647.1 MB) from volume Speedy Medien.
30.06.11 21:11:10 No pre-backup thinning needed: 1.08 GB requested (including padding), 911.18 GB available
30.06.11 21:11:15 Copied 2811 files (1 KB) from volume Speedy HD.
30.06.11 21:11:18 Copied 3059 files (1 KB) from volume Speedy Medien.
30.06.11 21:11:22 Starting post-backup thinning
30.06.11 21:11:22 No post-back up thinning needed: no expired backups exist
30.06.11 21:11:23 Backup completed successfully.
I don't know what made the difference and I do not know how long Time Machine behaves well from now on. But I hope, that the problem is solved.

Time Machine backup *incredibly* slow following full restore

I recently suffered a catastrophic failure of my hard disk, but was fortunately able to perform a full restore from TM, to a brand new disk. The restored system is as close to perfect as I would hope, with the usual minor omissions, such as recent mails etc.
However, I am finding it impossible to resume backing up to the TM disk that I was using previously, It takes a fair time to determine what needs to be saved, but then proceeds at a snail's pace - i.e. data saved is being measured in Kb, rather than Gb!
Could this be related to the FAQ issue about re-using the TM backup from a 2nd machine? It doesn't prompt me to re-use anything but I guess it might be getting confused under the covers. If so, is there any way I can 'fool' it into realising that it is still the same machine as before?
Note that I have run Disk Utility on the TM backup disk, and it all seems fine. Note also that I am connecting to the disk using Firewire, as I always have done.

I'm in the midst of a full backup using 10.6.3 on a new MBP. I turned it on nearly 4 hours ago, and it's backed up only 2.8 gigs out of 141. Now, that's slow.
Is this related to this thread (first backup after a full restore)? It doesn't seem to be.
What is the destination for your backups? If it's a Time Capsule, via WIFI, it's going to be quite slow, even with an excellent WIFI connection. I'd be inclined to cancel the backup, connect via Ethernet, and start over.
Whatever the destination, try the things in the green box in #D2 of the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
If none of that helps, a clue may be lurking in your logs. Click here to download the +Time Machine Buddy+ widget. It shows the messages from your logs for one TM backup run at a time, in a small window. Please start your own thread, with full details, and copy and post all the messages for the backup, too.

Time machine backups have slowed considerably since my installation of Mavericks -- why?
