Mavericks speed up time machine first backup.

to speed up time machine,(this worked for me.) just turn of firewall and turn off wifi and ry not to use anything. simple!

Oops!  Just discovered that Time Machine was backing up the other half of the partitioned disk.  I will add that to the list of things not to back up.  PFL

  • Time Machine First Backup After Upgrade Stuck @ Deleting Old Backups

    This has been going on for the past 4 hours.  Should I quit and start over.  I think I may have messed it up when I clicked the "Encypt Disk" during the first update...  Thanks...

    Quite possibly. 
    I don't know how long it takes to encrypt about 480 GBs, but it will clearly take quite a while. 
    See #31 in Time Machine - Frequently Asked Questions for some info on encrypting your backups.

  • Time Capsule / Time Machine First Backup

    Now in the 14th hour of wirelessly backing up the 40 gigs on my MBP to my new Time Capsule (i.e., less than 2 gb per hour). Can I safely stop and then connect an ethernet cable to TC to complete the backup? Am I likely to speed up the transfer by doing this?

    *"Can I safely stop and then connect an ethernet cable to TC to complete the backup?"*
    Yes
    *"Am I likely to speed up the transfer by doing this?"*
    Most likely

  • Time machine first backup

    I have 2 mac books and a 24" I mac. Just bought Time Capsule. Backed up fine on the Mac Books but it refuses to Back up the I mac. It says that The size is too big and the TC does not have space. I know for a fact that is not true. Mt TC is a tera, and the amount on my I mac HD is not more than 70GB. Collectively I have 240GB of Memory which is by far less than the Tera in my TC. Any Suggestions?

    run Applications-->Utilities-->Console, choose "All Messages" and search for "backupd." Read the messages from backupd, they may be informative.

  • Maverick and Time Machine and backup

    I moved to maverick. My time machine indicator at the top right of my imac does not spin when it is backing up. It used to with Lion. Is this normal.
    When adding Maverick. Is it normal my external hard drives seem to view the first back up and a new one, and is taking more than an hour to back up?
    thanks,

    Hi John et al,
    Update: Finally...
    At least for the Promise Pegasus R4... but I noticed on other threads that WD drives are also acting up too so this might work with them too.
    I turned off Time Machine, and deleted that pesky .plist file, again. I unplugged the R4, power and thunderbolt, then played whack the gopher with the drives swapping them around randomly.  I reintalled Mavericks from a fresh download, yet again, then set Time Machine to backup on a fast USB 3TB drive (which it did in 6 hours or so).  Then I turned off Time Machine, deleleted that .plist file again, rebooted the iMac, plugged in the R4, reformatted it again with Disk Utility, then hooked it to Time Machine, said a few slightly heretic prayers to whatever demons came with Maverick, and 2 minutes later Time Machine started to backup and report 1 hour to complete... the hour isn't up yet, but I'm crossing everything I have 2 of...
    I've noticed a few other 'didn't copy over or mesh well' things with Maverick, but that's a different thread and 2 updates from now once we all suffer through this extended beta-test by Apple.

  • Mavericks killed my Time Machine backups

    I have not been able to back up to my external  Time Machine disk since installing Mavericks.
    When I click on details, I see a message that says:
    Time Machine couldn't complete the back up to "my time machine drive name".
    An error occurred while copying the files. The problem
    may be temporary. If the problelm persists, use Disk
    Utility to repair your backup disk.
    I have used Disk Utilities to repair the back up.
    I restarted using the command R key combination and used disk utilities to repair both the backup and the system disk until no errors were found on either. But I still haven't been able to use Time Machine to back up.
    Suggestions?

    I went into the Console and looked at the logs for the past 2 failures and they seemed to die on the same files. Here's a sample log.

  • HT3275 Using time machine first time and the estimated time says 25 days. Wow! Am I able to use my Mac when Machine is doing its first backup?

    Using time machine first time and the estimated backup time says 25 days. Wow!
    Am I able to use my MacBook Pro when Machine is doing its first backup?
    I can't be without my computer that long. I would have withdrawal symptoms (very painful).

    Something WAS radically wrong, but I don't know what it was. However, using Apple's disk utility, I decided to totally erase the Seagate, which was "pre-formatted" for Mac and PC.
    I first saved the Seagate software to my hard drive just in case I needed it later (which I don't),
    By the way, the first time I tried Time Machine it stalled after about 3 GB. The second time I got the message saying 25 days backup time. I stopped that backup after receiving your response.
    After reformatting (extended - journaled) I made my third attempt. Success!!! It took about 8 hours, but went through without a hitch..
    I bought the SeagateI because a momentary power failure messed up my 1 TB LaCie external, which was divided into 2 partitions. The power glitch completely fouled one partiton and it will not reformat no matter what I try. I did not do a full reformat because I did not want to lose the backup on the good partition. Now that I have a good backup I plan to do a full 1 TB reformat (without partitions) on the LaCie.
    Thank you for your response, which really did help me.

  • Time Machine reports backup disc needs to be 8.78 Tb.  I only have a 250Gb system drive???

    Thought I'd do a TM backup before installing Mavericks.  It messed up big time!
    I backup manually depending on how much stuff has accumulated.  It varies between a few Mb to 3 or 4 Gb sometimes more.  Today Time Machine decided that it wanted to reorganise the backup in some way.  I watched as the available space on the TM disk went up as TM set about the task.  After a couple or three hours TM actually started to do the backup.  The size of the backup being 500Gb or something like that.  Several hours later of listening to my fans working flat out I cancelled the back up with TM reporting that there was 200 odd Gb to go.  No warning from TM to say this was a bad idea.  It had been chuntering away for something like 5 hours.
    After halting the backup I thought I'd start the backup again just to see how much more needed to be done.  This is when I got the report that the backup disk needed to be in the order of Tb. And the oldest backup is now Nov 2013.  The oldest backup before this was way back in June 2012 (MacBookPro Rertina mid 2012) when I first bought the computer.
    Entering TM I find that even that is not complete. All but a couple of applications have dissapeared as have many other files.
    Trouble is I use it as an archive and happily delete files on my hard drive knowing that there is a copy in a backup that pre dates the deletion. 
    There is also an earlier backup from my previous machine - again as a rarely accessed archive.  So that's another reason not to reformat.
    I'm pretty sure all is lost and I think I just have to bite the bullet and risk not needing anything from the archive.  After all I have CD and DVD backups/archives that go back to the late '90s and I have rarely needed to access them over the years.  The biggest loss will be photos.  ****!
    Anyway.  What happened?  Why has TM gone off the rails?  I have done nothing different to what I have done in 5 years or so.  Is this normal behaviour?  If I hadn't have cancelled the back up would TM have slowly rebuilt all my backups as was?
    Andy

    Trouble is I use it as an archive and happily delete files on my hard drive knowing that there is a copy in a backup that pre dates the deletion.
    Before going any further please understand that's a very bad idea. It's beyond Time Machine's scope to do that. It is not an archival system and cannot be made to become one. Time Machine guarantees nothing other than one complete copy of the source volume's contents. Anything erased from the source becomes fair game for Time Machine to delete from the backup, the moment it requires the space it occupies.
    Next: I have no idea why the problem occurred, but a first and harmless troubleshooting step is to reset Time Machine by doing the following:
    Turn off Time Machine first, and make sure a backup is not in progress.
    Triple click to select the entire line, then control-click and select Services > Reveal in Finder. Drag the selected file to the Desktop, or directly to the Trash:
    /Library/Preferences/com.apple.TimeMachine.plist
    This will not delete your existing backups.
    Turn on Time Machine and reselect your backup volume. The effect of deleting that file will cause erroneous values to be shown in the "backing up xxx of yyy" messages until the subsequent backup.
    If it's any consolation, terminating Time Machine as you did is not an abnormal user action and did not cause the problem. It may have resulted in inaccurate information being written to the property list, which you will fix by deleting it. It's quite possible that your backups have remained intact. Just remember that anything you delete from the source may no longer exist following the subsequent backup, and that is to be expected.

  • Is there a way to use Time Machine to backup my Macbook Pro to an external drive connected to my iMac?

    I recently purchased a Seagate Goflex Desk 2TB and I've already used Time Machine to backup my iMac running 10.5.8 to the drive. Is there a way to backup my Macbook Pro running 10.6.8 to the drive using Time Machine while the drive is still connected to my iMac? Any help is appreciated!

    Choose Connect to Server from the Finder's Go menu, provide the first computer's IP address, log in, and set it up in the Time Machine pane of System Preferences.

  • Time Machine thinks backup disk is full but its not

    I just purchased a new 1 Terabyte hard drive for backup. In the past I backed up both my internal Mac harddrive (250 Gb with 8gb free) and an external iOmega archive drive (DRIVE H 320Gb with 41Gb free) to a 500Gb Lacie drive. I purchased an iOmega 1 Terabyte drive (DRIVE G) because the Lacie drive was full. I went into Time Machine and changed the backup drive to the G one terabyte drive and did a full backup of my internal hard drive. When I did this I did not have the external H archive drive attached so Time Machine didn't back that up. I did it that way because I wanted to first backup the internal drive then do some work and then go backup the external archive drive over night. I plugged the H archive drive in, so it show up in the finder and then told Time Machine to Backup Now. It started the back up but right after doing the initial computations when it actually started backing up I got the standard error message that "the backup disk ran out of space unexpectedly..."  I've double checked that the backup disk is set correctly in Time Machine to the 1Tb G drive and when I do a Get Info on the G drive it shows Capacity: 1TB, Available: 713.54 GB.
    Is it possible something is wrong with the new drive? Can I test that?

    Its funny how sometimes asking a question can prompt  your thinking. As soon as I finished posting this I thought "of course Disk Utility".  I ran a check disk and got the following error message:
    Unused node is not erased (node = 107)
    I did a restore which corrected the error. Turned Time Machine back on and its backing up the rest of my data now.

    Annoying!

    Regarding time machine, it probably took a full backup after you put mavericks on. To investigate, open Console, select "All Messages" and type "backup" (without the quotes). It will then only show you backup-related messages. If you're not sure how to read those, copy them and paste them into a reply here; we can investigate the situation.
    I don't know anything about your PPC software issue, sorry.

  • Time Machine vs Backup

    I plan on reformatting my computer and would love to know if I should use Time Machine or Backup. I want to keep some of the programs and data from the computer, but not all of it. Which one will allow me to select data to "bring back"?
    Thanks for your help!

    Hi, and welcome to the forums.
    You do not want to use Backup for large amounts of data. It's fine for it's original purpose: to get relatively-small amounts of data off-site to iDisk, automatically, but don't use it for anything more.
    Time Machine will back-up your entire system by default. The first backup is, of course, lengthy, but thereafter it will back-up only new and changed items hourly. This gives you an excellent chance to recover things that were deleted or changed in error, or somehow corrupted. But whether you use Time Machine or some other app, use something or you can lose some or all of your data in an instant.
    But the question here is, are you doing this only to get rid of some apps and files? If so, that's not the best approach. Unlike Windoze, a periodic reload is usually not needed on Macs.
    Unless your internal HD is over 85% full, your best bet may be to get an external drive thats at least twice the size of the data on your Mac and let TM do a full backup. Then start identifying and deleting the things you don't want. If you delete something you shouldn't, you can easily get it back from Time Machine (for a while).
    Most applications on Macs can just be deleted. Some need uninstallers. Apps will be where you put them, hopefully in your Applications folder. Most data will be in +<your home folder>/Library/Application Support,+ usually in a file or folder containing the name of the app or maker.
    Unless you're very tight on space, you could make a folder named +Apps to be Deleted+ or something similar, at the top level of your home folder, and move them and their data files there, rather than delete them immediately. You could even create a sub-folder for those apps that have data files, and put both the apps and files inside them. Once you're sure they're not needed, delete them.
    Doing it the other way is much riskier; if you omit things you actually need, all sorts of things may go wrong, unpredictably.

  • Time machine fails backup

    Can anyone advise me?
    I use Time Machine to backup. All has been well the backups were flawless until recently when I decided that I needed to encrypt my sensitive work and personal files placing them into an encrypted Apple Disk Image on my hard disk. Ever since then at some stage Time Machine had decided that there is insufficient disk space and the backup fails.
    When it first began to fail I increased the backup disk space and began a fresh start backup.
    The backup disk is now 1 TB and the total amount on my hard disk to be backed up to backup is 183 gb which includes the disk image which is 40 gb.
    The only change has been the creation of the disk image otherwise everything else is the same. Would it be better to have a number of disk image files and spread the encrypted material across smaller dmgs?

    Thank you for your response which is very helpful. I have changed the dmg to a sparse bundle and Time Machine appears to be handling the backup better.
    Initially I was confused about the difference between a sparse image and a sparse bundle but read in https://discussions.apple.com/thread/2001162?start=0&tstart=0 what the difference is and see that the sparse bundle appears to have been developed by Apple for exactly my kind of problem.
    You say that "… be aware that disk image files are not backed up at all while the image is mounted."
    I do not wish to disagree but when I was backing up the vanilla dmg and also last night backing the sparse bundle dmg the back up has worked and did work on the mounted disk. In my case the disc is always mounted as it contains the bulk of the files I work on. Perhaps I have misunderstood what you were saying.
    Thank you again for your response.
