Time Machine not backing up - Backup disc could not be found

Time Machine has not backed up since April 2 because the backup disc could not be found.  It was working prior to this.  I cannot restore from prior backups - Restore button is greyed out.  Time Capsule is not connected in AirPort Utility.

Installed Dr. Cleaner 3/29 and Memory Clean 3/29 - both were updates.
That.....is the problem. Time Machine does not like "cleaners", "optimizers", "keepers".....anything like that. Your Mac does not need these types of applications since they generally do more harm than good.
Anti-virus applications will drive Time Machine crazy as well.
My advice would be to remove this type of software from your Mac according to the software manufacturer's instructions.
Then power cycle the entire network.
If the Time Capsule disk comes back into view, you should run a Verify Disk operation as soon as possible.  Your backups may now likely be corrupted, and if that is the case, Time Machine will not be able to back up until you erase the Time Capsule disk and try to start over again with a new backup.

  • Backup discs could not be read error occurred (-50). HELP!

    I'm using itunes 9.0.2; running Windows XP on Oracle Virtual Box in Ubuntu 10.04. the latest itunes will not work and 9.0.2 is the closest i can get.
    One out of 4 backup discs contains only the itunes purchases and it works but a message pops up: +'could not restore some of the files from the play-list'+, +'they may be on other backup discs'+ even though all the songs on disc play. I put the next disc in and the following message pops up: +'the disc cannot be read. an unknown error occurred (-50)'.+
    Any ideas why this is happening? I loaded the discs in the latest itunes on another PC and it is fine. would it be that I may be using an older itunes then when i backed up the other discs and so not compatible? is that possible??
    Any help on how to get all my music back on would be great!!

  • Time Machine: Problem selecting the backup disc - there is no option

    My Time Machine is innate, so to activate it I have to select a backup disc. The problem is that: there's no option there!
    What's the problem? Why this is happening?

    Hi, and welcome to the forums.
    If you mean your disk doesn't show up as a possible destination, see #B1 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).
    If that's not what you mean, please clarify.

  • Time Machine-restoring from a backup that is not the most recent

    My hard drive was failing so I backed it up to Time Machine and had it replaced. It failed again and I replaced it again. The trouble is that the backup seems to also have become corrupt. The Genius Bar told me to try restoring from an earlier backup, but it doesn't want to do that. Migration Assistant doesn't let me choose the earlier date and Time Machine won't replace the entire drive, refusing to replace the Applications and Library folders. If I boot from a different disk I can't choose the destination.
    Even though the earlier backups are probably fine, I have no way of recovering them without some guidance.

    I found the answer. The way to access the earlier backups is to boot from the 10.6 install DVD while the Time Machine drive is attached. Choose the primary language, but then instead of proceeding with an install and using the transfer near the end, go immediately to the Utility menu and choose Restore From Time Machine. It will display the Time Machine Drive and allow you to choose a backup by date.

  • The ipod could not be synced. the disc could not be read or writtern to

    Hi,
    I am having some major problems with my Nano. I upgraded to the new firmware through the new iTunes about 10 days ago, but now it just doesn't work all I keep getting is the above message. What is upsetting me is that it worked fine until this firmware update.
    I have tried following the other advice including resetting it, I have also tried factory restting it through iTunes and it still doesn't want to work.
    I am running XP Pro SP2, and you cannot see the Ipod in the list of attached disc drives.
    Please help as my nano is now useless.
    Thanks

  • Time Machine error "The backup disk could not be found"

    I use Time Capsule with Time Machine, Lion OS and manage to setup successfully. However after I on it for few hours, there is backup error. Time Machine error message "The backup disk could not be found." But the internet wifi is working normally.
    To solve this issue I have to power off and on it again, then the disk can be detected. But after few hours same thing happen again.
    Is it a hardware faulty or sometime that cause the Time Capusle harddisk to sleep after sometime?

    I have this exact same problem.  When I restart the Time Capsule I can then start backups normally, but it requires manual intervention.  That's dissapointing because Time Machine and Time Capsule are supposed to be an automatic, worry free backup.  I have to restart the Time Capsule frequently.  Annoyed.

  • "back up disc could not be found"

    my time machine is saying "backup disc could not be found" any suggestions?

    apparently I needed to upgrade the time capsule software.  duh!

  • Time Machine to back up MacBook AND External Drive?

    I have a MacBook and a 1TB G Drive which holds all of my photographs and iTunes library (none of which is on my MacBook, since I ran out of space long ago), and where I have backed up my Documents folder by simply copying and pasting.
    I bought another 1TB G Drive to use as a back up, but I have no idea what I'm doing. The first time I backed anything up I just copied and pasted again, from both the first drive and my MacBook, which is ridiculous and took hours and is pathetic.
    I want to set up Time Machine so all of my applications and settings are backed up, in addition to my files which are in two separate places right now. I'm not sure how to set up the second drive to take care of both.
    After looking at the FAQs at the top of this forum, I'm afraid that any partitions I set up may re-format the drives and thus wipe out everything I have. Any advice on how to set this up without losing my data would be appreciated. Thank you!

    That may not be large enough. It varies greatly depending on how you use your Mac, but Time Machine usually requires 2-3 times the space of the data it's backing-up. So add-up the space used on your MacBook's internal HD and the amount used on the other drive. If that's less than 500 GB, you'll probably be fine. If it's between 500 GB and about 750 GB, it might work, at least for a while.

    Most likely, piece of cake.

    No, Time Machine won't wipe out your data.
    First check the Format of the media drive. You can do that via +Get Info+ in the Finder. In the General area of the Info panel it will show Format. If it's any variation of +Mac OS Extended,+ then Time Machine can back it up. If not, your best bet will be to switch drives -- format the new one for your Mac, copy the data to it, then erase and reformat the old one to be used for your backups. Post back for instructions if you need to do that.
    You should erase and format the Time Machine drive with a single partition, per #5 in the FAQ.
    When you're ready to start Time Machine, click the Options button in Time Machine > Preferences. See if the media drive is listed in the exclusions box; if it is, select it and click the minus sign. Then Time Machine will back it up.

  • My time machine back up failed because it says the backup volume could not be mounted

    My time machine back up failed because it says the backup volume could not be mounted.  What does that mean and how do I fix it so that it backs up?

    A  whole  lot  about  Time  Machine for help with TM problems.  Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM.  See also Mac 101- Time Machine.
    Use Disk Utility to repair the TM drive.  If that doesn't help, and you don't find help from the above, then erase the drive and start a new TM backup.

  • I am trying to get space on an external hard drive which has some old time machine back up files that I do not need but can not eliminate, even by going into the time machine, clicking on the backup file to be eliminated and using the drop down eliminate

    I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
    You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots.  Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
    See Pondini's page for more explanation:   What are Local Snapshots?   http://pondini.org/TM/FAQ.html
    I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
    You have tested the library on the external drive, and so your photos are save there.  
    The local TimeMachine snapshot probably now contains a backup of the moved library.  Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.

  • Time Machine Contradiction: "The backup volume could not be mounted"

    (This is only one wireless issue I've had this year, but I'm trying to keep this brief -- hoping clarity will instigate some help.)
    Recently I bought a Western Digital 500GB drive to go with my AEBS. I was intent upon using the drive as an Airdisk for Time Machine backups, but it isn't working. (I also have the WD drive partitioned in halves, but there is no reason to believe that is an issue.) When wired, the disk backs-up quickly and easily. After the initial backup, and attempting to do so wirelessly, however, it doesn't work. I get the message: "The backup volume could not be mounted."
    And there's the contradiction: the disk is mounted, I'm looking at the mounted disk as I type -- I even have no problems reading and writing from the Airdisks independent of Time Machine. I have all the latest software updates and am running Leopard. I've been going at this for hours, but I would really appreciate some help.
    Here are some of the things I've tried:
    -checking all connections
    -erasing the Airdisk and starting from scratch
    -repairing disk permissions(on my internal harddrive, the one I boot on, not the WD)
    -attempting to "Connect to Server" in the Finder, only to get this:
    And if you look, you can see that while the Airdisks are there, they are grey and can't be selected. It
    never becomes possible to select them, and "Connecting to Server" never connects.
    -I've toggled every Airport Utility setting to no avail(I will admit I might have missed something though).
    -I've done everything I can think of
    -banged my head into walls...
    -and pulled my hair out, but nothing.
    I really would like to get this working. This is my worst Apple experience yet, and it is literally making me sick. You will be my God if you can help me with this. Let me know if you need anymore information. Thanks in advance.
    <Edited by Moderator>

    Okay, so it seems you need to do initial Time-Machine-ing over WiFi if you intend to use it that way. Why nobody at Apple mentioned this baffles me; why this is even a problem, makes me wonder if Time Machine went through adequate testing.
    So my problem is solved! I am my own God!

  • Time Machine - "The backup volume could not be mounted" alert

    This is a heads-up for anybody suffering from this error when performing Time Machine backups:
    "The backup volume could not be mounted"
    I had been using this facility fine for months until a few days ago when backing up mysteriously failed. The Apple support KB articles didn't help (eg, reset time machine drive setup, etc).
    Apple Support didn't want to help me because they don't "support backups over networks" - sheesh! What happened to "Think Different!"??
    Drag and drop your SPARSEBUNDLE file from your backup drive to the Disk Utility.
    Perform a Verify Disk operation by clicking on the button.
    A normal backup should be able to perform this procedure, but a corrupted one won't.
    When trying to perform this on my backup, the Disk Utility would simply return to the original screen without performing anything a second after pressing the button.
    In this case, I found deleting the old backup file and starting from scratch restored my computers ability to perform automated Time Machine backups.
    I have concluded that the backup file became corrupted in some way - several previous posts have pointed to systems going into standby while backing up files as the cause of this.
    Hopefully someone finds this useful one day.

    There is a Time Machine preferences file at
    <your startup drive root>/Library/Preferences/com.apple.TimeMachine.plist
    Note: This is be main Library folder, not the one in your user folder.
    You might try moving that to the Desktop so that the system creates a new one.

  • Time Machine Error - The backup image could not be mounted

    Bought two new MacBooks.
    Put first MacBook on LAN connected to TC.
    1. Selected Use Time machine Backup
    Selected TC
    It then sat there for 3 hours "Checking Time Machine Backup.....
    The only way out was to power off and power on again
    Did 1 again, and again , and again
    By now the two iMacs are now reporting either the backup image is Read Only followed by The backup image could not be mounted!!!!
    So it seems that the two new MacBooks cannot use TM backups and c]have corrupted our backups!!
    Tried calling Apple Care, which I paid for both MacBooks - but they had closed. That was a very useful £400 spent!!!!!!
    Arrrrrrgh I had just been bragging about how easy Macs made things
    Very frustrating
    If I cannot get these going tonight they are back in the box and back to the store in the morning

    OK
    Called Applecare - took out the £195 Applecare option when I purchased the MacBook.
    The AppleCare guy told me said first:-
    The TimeCapsule is broken take it in for repairs.
    I pointed out the TC was working fine.
    Then :-
    After explaining again that the Macbook had been sitting for several hours saying it had 1 minute to go before finishing.
    "My supervisor says Macs take longer to do things than PCs, give it another two hours then if it still hasn't finished it's last minute call us back.
    I challenged him on this he put me on hold again for 10 mins and eventually hung up on me.
    That was why I paid and extra £195 for telephone support!!!
    Called back again and very helpful guy walked me through some options and escalated to Tier 2, couldn't get anywhere so the only thing left now is to return the MacBooks to the store.
    It Appears that Macbooks are incompatible with the Time Capsule.
    Never mind Windows 7 is coming soon and I am hearing good things about it.
