Start up disk back up

hello, i am a video editor/ motion graphic designer. i have an 8 core 2,8 mac with 16gb RAM a start up of 750 GB, a 500 where i store sound loops, and certain often used data, and a 1 tb raid where i have my personal projects and so on...when i work i use an external raid house for the big data connected by a esata card...
until now i have always used super duper to back up my start up disk. i just bought a 1 TB drive and thought about using that with time machine. i have never used time machine and i would looking for advice... woul it be wiser to use such a 1 tb drive as a backup to my start up disk, or possible as a back up for one of my other disks, should i stay with super duper?...is there place i can read up on time machine to get a better idea of what it does and how/if it suits my needs?
thanks a lot for the help...

The general rule of thumb is to have the TM backup drive be 2-3x bigger than the data that is being backed up.
For more info on TM, and how it works, see this ars technica review of it.
Good luck!

  • How do I switch the Start Up Disk back to Mac OSX hardrive ?

    Hi Mac users....
    I think I created a huge problem on my computer. I was looking to stop a program from opening up, snapz pro x, every time I restarted my computer. I found out how to delete eventually, but during my search I went to system preferences...than hit startup disk...then clicked on Network startup without switching back to Mac OSX hardrive startup. When I restarted the computer it only flashes a small world button logo and doesn’t reboot. How do I get back onto the computer to change it back to startup with MAC OS X on Mac system. Would I hold the control button down while restarting? I am worried...I hope I didn’t crash my computer? Thanks for help in advance. Please email me if this is quicker to respond.

    Hi,
    Welcome to the Discussions.
    Hold down the option key while starting. That will launch Startup manager and you can choose your drive there to start from. Once started go to System Preferences>Startup Disk and select the hard drive again.

  • If I can't find the start up disks, is there anyway to get iWork back after installing a new hard drive?

    I had to install a new hard drive because my orginal one crashed. When I bought my macbook, iWork came pre-installed. Now with a new hard drive I would like iWork back on my computer, but can't find the start up disks, assuming I'd be able to do it that way. Is there anyway I can contact Apple and have them give me the iWork software?
    (Overall, very upset about this since my macbook is only 2 years old and I lost everything. A friend of mine has been working on it for 3 weeks trying to recover some data.)

    - Did you restore from a backup that contained the photos?
    - The backup only contains photos in the iPod's Camera Roll album. It does not included photos synced to the iPod.
    - All you can do is try restoring from backup again.

  • I have a G5 imac that is using Disk Warrior as the start up disk and can't change back.

    I am using a G5 imac (OS 10.4.8 I think the last update is) and I was attempting to use Disk Warrior to recover a lost file. On my other Macs you made Disk Warrior the start up disk to use it, which I did here but I think that was a mistake. Now I can't change back to the regular start up disk.
    I tried starting in safe mode but I think I'm getting kernel panic because it goes to a gray screen and tells me to restart.

    I don't think Disk Warrior does file recovery. See:
    Basics of File Recovery
    Files in Trash
    If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location.  OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
    If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone.  Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
    General File Recovery
    If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro.  Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.  Two free alternatives are Disk Drill and TestDisk.  Look for them and demos at MacUpdate or CNET Downloads.
    The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

    There is nothing wrong with the OS update.
    Delete ALL your email accounts.
    Restart Playbook
    Put the accounts back and ensure they are all set with PUSH ON.  Manual (push off) will burn battery.
    Similarly delete your wifi connections and add back when required. 
    Turn off wifi is not connected to wifi. 
    Any "hunting for connection" in email or wifi will burn up battery.

  • Start up disk was full and i guess I changed the start up disk by error and now I can't see the dock and not able to change back to original start up disk

    I tried to delete start up disk files and messed up, galaxy screen only comes after I log in, no dock, won't take start up disk, can't get to utilities to try and fix it

    This document should help. It sounds like you just need to reinstall the OS using the install DVD's that came with your system.

    Hello Mac4541,
    It sounds like you may have reinstalled OS X on your 2008 MacBook and iPhoto didn't get installed.

  • I bought a new Macbook Pro with Retina (13") a few months back and all of a sudden saw my opened programs got paused with a message that I should free space in my start up disk. Any help?

    My opened programs got paused and I got a message to free up space in my start up disk. It asked me to quit some apps. I checked and found that I did not heve lot of apps opened. How do I troubleshoot this?

    How much free space do you have on the flash storage device? Go under the Apple menu to "About This Mac..." then "More Info..." and look at the storage tab. Post a screenshot of you Storage tab in a reply here (http://support.apple.com/kb/PH4391).

  • How to get windows partition back on start up disk

    I have used boot camp partition (windows) for months without any problem. I recently installed VM ware fusion. But unfortunately it did not work properly so I had to uninstall it.
    Now I can no longer reboot from 'system preferences / start up disk' since the windows partition no longer appears beside OS X.
    Can somebody help me?
    Thanks
    Phalch
    NB I can still reboot windows when I restart the computer with alt key pressed.

    You probably want to post your question in the Intel-based iMac discussion area instead of here in the discussion area for the much older iMac G4.

  • How to delete files from start up disk

    Please help. After my macbook air is on for 2-5 mins, it comes up with I need to delete files from my start up disk. I went into start up disk and the only thing in there is the OS X system. So, then a small box appears. and tells me my memory is full and that I need to force quit applications. Sometimes the only application that is on it is finder. At this point the macbook air then freezes and I have to turn it off holding the button down. When I go to turn it back on it will often not turn back on. This laptop is only 11months old and running the new OS X system (mountain Lion) that just came out.

  • Imac will not see my hard drive on start up, wants to start from network start up disk that does not exist. How to get rid of it? So there is just one choice / my hard drive.

    I have a Intel duo Imac. Everything has been running relatively smoothly for a few years now. All of a sudden my computer will not start. I get the flashing folder with a question mark.
    When I go to Start up disk in my system perfernces while the computer is on. I see 2 possible choices. One is my hard drive with the operating system shown. The other is a non-existant Network Start up disk with a question mark in it ( looks like a hard drive with a question mark and it say's its a "network start up disk).
    All I think I want to do is get rid of the Network startup with the question mark. I can not find anywhere how one can just remove an old or non existant start up disk without reformatting.
    I believe this came from a clients hard drive who had a network system on it. We no longer have that drive. It no longer exists. But a latent icon shows up in start up disk.
    When I go to change the start up disk. I can change it to either the hard drive or the network with the question mark. But when I select my hard drive and then got to restart the computer. I get the flashing folder with a question mark on start up. I have also seen the flashing globe a couple times.
    When I attempt to run disk utility from may install disk ( holding down "C" on start-up ). Disk utility does not see my hard drive. Just the Apple install disk with the disk utility on it.
    What can I do to remedy this short of re-installing? Will a program like Disk Warrior or Tech Tool help?

    Thank you. That's what I thought will need to happen.
    One more question. I tried using the Apple install disk that came with the computer. It's an OS 10.5.6 disk. It does not see my 10.6.8 system internal hard drive to repair. All it see's is itself 10.5.6 disk. Do you think I can use a 10.8+ disk utillity since that is a higher system it will see the 10.6.8. Where the 10.5.6 does not?
    I don't want to turn the computer off for fear I'll get the question mark again. P-Ram got me going last time but for how long I don't know?  It would be nice to be able to turn the computer off for the night and startup as usual to give it a rest and try to reset itself.
    Thanks for your help, I know I will eventually need to re-install. But I am in the middle of a project with tight deadlines and all I can do right now is back-up. Trying to migrate to another computer temporarily to finish the job. That's a lot of extra work in the short time also.
    Just trying to put a band-aid on it for another couple weeks.

  • How do I make multiple start up disks

    I've partitioned my Imac(intel) for lion and leopard but can only start up in leopard. how do I make both partitions start up disks?

    Frankly, I'm stumped because I didn't know that Time Machine backups are bootable?
    The backups aren't, but when you restore them, the result is bootable.
    And, effective with 10.7.2, if you back up to a directly-connected external HD, Time Machine copies the Recovery HD to the Time Machine drive, so you can start up from it if your internal dies.
    Take a look at this site (in particular scroll down to Time Machine):
    Just for future reference, since Apple's dropping web hosting via MobileMe, I've moved my site.
    The new version is at http://pondini.org
    I'll leave the old one "as is" for a few days, then put redirect notices on it until it goes "poof" in June.

  • 'No' symbol on start-up, disk utility not recognizing internal drive

    Need a little assistance.
    Two days ago I was using the Macbook and it froze. Restarted and I was hit with the international no symbol. I've also gotten the blinking file folder at times when I've tried the holding down of various buttons on start-up.
    I put a Hitachi 750 gb harddrive in last fall, it has been working fine up until now.
    I do not have the system disk for Snow Leopard on hand, so until I can get it from my Dad, I decided to check on the system disk I actually have from the laptop purchase in 2007.
    This allowed me to get to the start-up disk and disk utility area. I could not find my external harddrive in the list for a start-up, and it is the back-up using Time Machine. I also could not get the internal harddrive to be found in the utility so I could do a repair. It did seem to recognize that there is a drive, but not the actual named portion of it that contains the info.
    I removed the internal and put it in an external case: my netbook recognizes that there is hardware, but does not let me access it. I attribute this to the fact that the drive is formatted for Mac and the Windows machine can't recognize the data.
    My next step was to see if my old iMac would recognize the internal as an external, but since I don't know where the keyboard is and it is running an early version of OS X, figured it won't do me much good.
    What is my next step? Will the Snow Leopard disk make a difference? Or is the reaction with the older system disk going to carry on the same way with Snow Leopard?
    I was going to buy a Macbook Pro, but not for over another month, so I'm hoping I can figure something out with this and make it last a little longer.

    I hooked my internal as an external up to my Mom's Macbook Pro and it recognized my HD. I'm thinking it is something internal with the hook-up, which is awesome, because maybe I can actually fix it!!!!  Any thoughts?
