Time Machine Backup on External Drive Stops working after one week

Hello,
I'm having a problem with the Time machine backup on an external LaCie drive. After e few days, it suddenly locks up, not performing any backup unless I force-restart my computer and switch off the drive.
*My setup*:
- iMac Alu 24 with MacOS X 10.5.1 and 3Gb RAM
- LaCie external drive 320 Gb - design by Porsche, connected to the FW 400 port of the iMac --> this is the one used for the bakcups, it is left powered on at any time (never switched off)
- 2 other LaCie external drives 160 Gb - design by Porsche, connected to the FW 400 port of the iMac --> they are generally switched off
TimeMachine is setup to its default scenario, backing up automatically on the external 320 Gb.
*Daily usage* :
- the iMac is set to boot automatically at 6:45
- I usually switch it off manualy at the end of the day
- Screen Saver is set to launch after 5 minutes
- sleep time for computer is set to 1:30 hour
- display sleep 15 min
- hard disk are set to sleep whenever possible
First symptom : the computer never goes to sleep
Second symptom : I had the following problem already twice since I installed Leopard, once with the original install and today with the updated 10.5.1 version:
- automatic backups went fine during the whole day : 7:45 8:45 9:45...
- then an automatic backup starts but never finishes
*Console log extract* :

  • Time Machine backup on external drive no longer working after upgrade to Yosemite

    Can anyone explain why, after upgrade to Yosemite, Time Machine is no loger working? Backup on external drive stops few seconds after it has started. What can I do?

    Welcome to Apple Support Communities
    Try running a DVD Lens Cleaner disc through it, a little bit of dust or dirt is all it takes to throw them out and it might just be co-incidental with the upgrade.

  • Time machine backups to external drive causing kernel panics

    Hi,
    I am using an early 2011 MBP with a 1TB WD My Passport as a Time Machine backup disc.
    Time Machine has been working fine until 2 days ago when I tried to perform its backup to disc.
    It performed the usual backup but only up to 50MB of 2GB before it caused a KP.
    Tried it using a different USB port with the same results.
    Here's the report:

  • Time Machine - Backup/verify external drives, etc.?

    I store files (primarily large photoshop files, and misc digital photo images) on external hard drives. I plan to consolidate all photo files from older drives to a new 4Tb drive. (Will make also make a duplicate of that drive) The older drives are of an age that they may fail at any time. I know that I can simply COPY the files to the new drive, but I won't know if any of the files become corrupted during the transfer. I used to use Retrospect, which could copy and (very slowly) verify/compare copied files. I am new to Time Machine & don't see options for transferring files from specific external drives to a designated destination. And I don't know if Time Machine verifies/compares files -?
    If this is not possible, is there any way to ensure that copied files are transferred intact using OS 10.7.5? It would be impractical to open all the files after transfer.
    If this is NOT possible, can anyone recommend a RELIABLE copy/transfer utility that can verify/compare copied files? I only know of retrospect -which I haven't used recently.
    Thanks

    Does anyone know if it's possible to use two separate external drives in Time Machine to backup different parts of my mbp hard drive? That is, I want to use ex.drive1 to back up work files at work and ex.drive2 to back up personal files at home. In time machine options, I can set the folders for exclusion, but currently have to set those each time I back up at home/work.
    There's no easy way to do that with Time Machine. As you see, it only has one set of exclusions and one destination drive at a time.
    In theory, and if you're careful, you might be able to manipulate the preference file where all that's stored. Set TM up for home, say, then copy or rename that version. Then set it up for work and do the same.
    The file is at the top level of your drive, not in your home folder:
    /Library/Preferences/com.apple.TimeMachine.plist
    You could probably write an Automator workflow or AppleScript to simplify swapping the files.
    Otherwise, two alternatives:
    Back up everything in both places.
    Use Time Machine at home, and a different app, such as CarbonCopyCloner or SuperDuper, at work, or vice-versa.

  • Question about Time Machine backup on external drive containing photos

    I have a Le Cie external hard drive with iPhoto '08 photos on it.  I bought the drive when I started running out of room on my early 2008 iMac and moved a bunch of iphoto pictures and imovie movies onto it.  Can I use this same external drive to run Time Machine backups?  Or would that risk losing the photos that are already on the external drive??  Can an external drive be used for both photo storage and Time Machine backups?
    Ultimately, my goal is to update to iPhoto '11, but I would like to have all my photos backed up first in case it doesn't go well. 
    Thanks!

    Yes. You can back up your internal the external drives to the TM drive.

  • Time Machine Backup on External Drive Invalid sibling link

    I've used time machine to backup macbook air for several months.  From Feb 2011 without any problems until about 2 months ago.  I started to get the message that backups could not be started.
    I realized that the disk would not mount right away.  And after about 10 minutes or more I would get the message that my disk could not be mounted.  The error said my data could be backed up and I should do it right away.
    Okay, so I try to copy my backup files using finder and get an error saying I don't have permissions to copy data.
    My research indicates my hard drive is failing, which is unfortunate, since I bought it within the last year :-(
    Okay, so now I am trying to get my months worth of backups off the drive and this is proving to be quite difficult...actually, impossible.
    Here are my latest attempts at resolving my issue:
    1.  Ran Repair Disk - reusts:
              error:  Could not repair disk and something about backing up my data and reformating the disk
    2.  Ran fsck_hfs -f command in terminal
         The system indicated it was executing the command and about 2 or 3 minutes, I think the command prompt appeared.  No other message
    3. Run repair disk again - My results:
         Checking catalog file.
         INvalid sibling link
         rebuilding catalog B-Tree
         The volume My Passport could not be repaired
         Volume repair complete
         Updating boot support partitions for the volume as required
         Error:  Disk Utility can't repair this disk...disk, and restore your backed up files
    4.  Created a new partition on another external drive and did a restore in Disk Utility from the broken drive to the new partition on the other drive.  Took a few hours.  Unfortunately, I just created the same problem on that partition (invalid sibling link)
    Any other ideas on how I can rescue my backup data from the My Passport drive? I can see it in finder but I can't copy it do my other drive!
    Research on forums and other sites have mentioned cloning the drive using "dd" command.  Is this the same as the disk utility restore?
    Is there some way I can change the permissions of the disk/partitition/files to enable me to copy the data to the new external drive?
    Here is what the system looks like:  Mac HD is my mac mini; My book is the WD 1TB external drive usb connected;  My Passport is the broken external drive with the time machine backups that I can't get access to.

    ***Update to ask question***
    I would love to setup my new mini like my MBA.  Is there anything wrong with restoring my entire drive, I think it starts at /User/ level, to my mini????
      You know you never know when you will need the backups.  This makes me angry especially since I can see the files but can't repair the disk.
    OTOH, I attempted something I just now read about, option-click on time machine icon. Funny thing, I selected other disk and my passport (original broken drive) popped up with time machine backups on it.
    I, quite timidly, selected the disk, opened the time machine and traversed my broken drive with backups from feb.
    hmmm.  I then, selected some random pdf file to restore and behold, It was restored to my mac mini right before my eyes.
    I'm confused.  But I think I will go with your suggestion and just put the drive away in a closet somewhere and hope to never really need it.  It is quite interesting though that I am unable to repair this disk but I can restore files from it....Odd, I tell you, odd....
    Thanks

  • Time machine backup on external drive shared with windows PC

    Can I use time machine to back up files on my mac to an external hard drive, which also is used to back up files on my windows PC? Can time machine do this without erasing my pc's files?

    The only way to accomplish this would be to partition the drive. The partition for Time Machine needs to be Mac Extended (Journaled) GUID. Once partitioned and TM is backing up to the Mac partition, it won't effect the other partition that has your windows backup.
    You may need to move your windows backup elsewhere temporarily in order to partition your drive then move it back to your windows partition. -GDF

  • Time Machine backup of external drive

    I just noted that Time Machine is not backing up my external hard drive.  This drive contains my photos.  Can I set up TM to back up this drive too?

    Hi guys,
    I have similar a similar question but am confused by the response.
    Right now I have a 1 TB HDD in my IMac (about 200GB full), along with a number of external HDs == 911 GB (out of 1 TB) & 73 GB (out of 320 GB) used.
    Currently I have a 1TB ext drive that I use to backup my main computer HD to Time Machine. I really want to back up the other drives too, but am worried about disc usage, and having a big enough external drive to have everything on.
    Is it possible to have time machine split backups across multiple discs?
    Ideally I would buy a 3 TB drive for TM backups and just select EVERYTHING that I want to do, but i don't know if USB ones exist, and they are probably expensive.
    Let me know if you have ideas. Thanks!

  • Time Machine backup from external drive to MyBook World

    I'd like to back up my external flex drive (w/ about 350gig of pictures) to my 1TB MyBook World which is connected directly to my router (and not my laptop).
    My Macbook Pro recognized the drives, I seemed to have everything set up ok. When I went to do my backup I realized that the estimated total backup was only 60gig... clearly the external wasn't included. I went to see the files that were showing as excluded in options & that drive was there. I deleted it from external & in options, the new backup size looked perfect.
    Then when I went to actually run the backup, it says Backing up 1.32 gig of 60.67 gig again. When I go back to Options it looks correct in there.
    Am I missing something? Keep in mind that I've only been using a mac for a week & 1/2 so I'm still trying to catch up on knowledge.

    Thanks for your suggestion. I don't use iPhoto (I use LR and Photoshop & both were closed).
    I called apple care support & he said to let it run through the initial backup (which indicates that I only have 60 Gig to backup instead of 400ish Gig) and then to call them back. I will wait until the first backup is completed (hopefully today) and then I may try your suggestion.
    The exclusions initially included my external drive and I noticed it right after the backup started. I stopped the initial backup, removed the external from the exclusion list & then restarted the backup... but it was still showing a very small backup. I guess it could have somehow got messed up.
    Again, thanks for the suggestion.

  • HT201250 I have 2 Lacie external drives connected to a Windows PC.  What is the best scenario for backing up files on both computers?  I would like to save all my files on one backup drive and have Time Machine backup that external drive to the other.

    I don't know if this is a good idea, because the external drive is going to be slower than using my local hard drive to open files from.  My IMac has 1tb and the 2 external drives have 1tb each.  The IMac is my computer and my Wife uses the Windows PC, so I have to make sure both of our files are backed up.  Thanks in advance for any advice regarding this issue.

    I'm in a similar situation including movies I've purchased from iTunes...
    Here's my setup:
    I have all my iTunes data (music, movies, etc.) as well as about 10 GB of photos stored on a nework storage device that uses RAID-5 with SATA disks. This is basically a little toaster-sized NAS machine with four hard drives in it (www.infrant.com). If one of these drives dies, I get alerted and can insert a new one without missing a beat since the data is stored redundantly across all drives. I can also just yank out any one of the four drives while the thing is running and my data is still safe (I tried this after I bought it as a test).
    That's how I prevent problems with a single disk... Redundancy
    Now onto "backups"...
    Nightly, my little RAID toaster automatically backs itself up to an attached 250GB USB drive. However, these backups are only of my critical data... documents, photos and home movies... I don't bother backing up my "Hollywood" movies since I can live without them in a disaster.
    ... I actually don't permanently store anything I care about on a laptop or a desktop. It all goes on the NAS box (Network Sttached Storage) and then my other computers use it as a network drive. It's attached via Gigbait to my main computer and via wireless to most everything else.
    My achilles heel is that I don't store anything outside of my house yet. If I was smart, I'd alternate two USB drives attached to my NAS box and always keep one of them somewhere else (Safe Deposit Box?).
    ...and that's just one way to do it.

  • HT201250 Time machine backup to external drive

    I have left my backup drive plugged in overnight after not using it for quite a while.  Time Machine has not updated my backup drive.  Do I need to do more than plug it into the USB port?

    Be sure Time Machine and the drive are both ON.  Try a Back Up Now from the TM icon in your menubar, and see what happens.

    Is it possible to have Time Machine backUp computer HD AND external HD connected to Airport Extreme.
    Sorry, but no.
    Time Machine will backup your Mac, but not the hard drive attached to the AirPort Extreme.
    Time Machine will back up a hard drive only if it is attached directly to your Mac via USB or FireWire.

  • Does Time Machine backup other external hard drives?

    I am using a Seagate 500 GB to backup my data. Will Time Machine backup another external hard drive on which I store my iMovie projects? If so, how do I access them in the Time Machine mode? Thanks in advance.

    nachdenki wrote:
    strange, my external HDs were added to the exception list automatically. maybe because they wouldn't fit on the time machine volume.
    It seems to depend on when the drives were connected. When you first turn Time Machine on, it only excludes the TM drive itself, and any drives not formatted HFS+.
    If you connect a drive later on, that drive will be excluded automatically.

  • External Drive with Time Machine, booting from external drive with utilitie

    I'm using Time Machine now with
    a LaCie 1TB external hard drive.
    Everything works fine.
    But, I've been wondering:
    Can I place a program like TechTool
    on the external drive (that Time Machine uses)
    and boot from that external drive.
    I would like to be able to do that,
    because diagnostics and repair programs
    only works properly and fully when they run from
    external drives. Anything on the internal drive can be repaired
    and examine. Impossible to do if Techtool is on the same
    drive that's been examined.
    Any thoughts as to what I should do?

    Isn't there many versions of the OS on the Time Machine backup taken at different times?

    As V.K. says, you can't boot from TM backups.
    But you can restore your entire system from any one of them, per the procedure in #14 of the Frequently Asked Questions *User Tip,* also at the top of this forum.
    You can also selectively restore from them, while running normally. See #15 in the FAQ Tip.
