Simple backup question

I just bought an external hard drive and i am in the process of using time machine to back up the hard drive. The reason i had to do this was because my hard drive was full and really killing the performance of the computer. So the whole point was to take some things off the computer and store them on the external. is this what time machine is doing? or with the "snap shots" it takes am i going to alter what is going to be stored on the external. I just want to free up some computer space and keep the info. As always, thanks.

boxofrocks,
The first question we should probably ask is: "How large is your new external drive?" Another one that might be helpful is, How much data do you have stored on your internal hard drive?"
Let's say that you have 100 GBs of data on your internal hard drive. You'll need at least twice that much external storage space for use with Time Machine, preferably three times as much. How large is that external drive? For now, I'll assume it is 500 GBs. If you partition it with two volumes, one volume of 250 GBs and another using the remainder of the drive (which will come out to around 210 GBs), that should leave you with plenty of room for both of your current needs.
Time Machine will be happy backing up to that 250 GB volume, and will remain happy for quite some time, if not indefinitely. The second volume you would use to store the "overflow" that you currently have on your internal drive. These files would be removed from that internal drive after copying them to the second volume, thereby relieving the stress on both your internal drive and Time Machine.
Off the top of my head, the largest "space consuming" files are probably going to be things like videos you might have in iTunes. If you have movies or TV shows that you have already viewed, these con be copied to the second volume of the external by dragging them there from within iTunes. These files can then be deleted from iTunes, moving them to your trash (which you would then empty to free up the space).
Another good candidate would be any iMovie or iDVD project files. Disk images (especially large ones) should also be copied to the external, then deleted from the internal.
As has already been stated in this thread, you wouldn't want to have Time Machine making backups of that second partition. Make sure you "exclude" it in Time Machine's preferences. This does bring me to another consideration, especially if your external drive isn't large enough to accommodate all the suggestions I have posted so far.... Namely, the possibilities presented by the use of two separate external drives.
If you had two external drives, or if you are forced to purchase a second because the first is not really large enough (remember, you'll need at least twice as much room there as what you currently have on your internal), you could use Time Machine to create a backup that contains everything you keep on your internal, and any additional files you keep on the second external. In this way, Time Machine would keep a backup of every file you have, in any location.
When you set up Time Machine, it will make a backup of every volume that is mounted at the time that it begins the first backup. It does this by default, unless you specifically exclude some volume(s). This is the option that would provide the most security for all of your data.

  • 4 Simple Flash Questions that Are Stumping Me!

    What is the Frame Rate for Web Animations
    Q1. I am making an animation which will be played on the web. What is the default frame rate (fps) of Flash CS5? And what is the frame rate of for web?
    Q2. My animation needs to be 30 seconds long. So at 15 fps that would mean I need to use 600 frames in Flash?
    How Do I Mask everything so all I see is the Content on the Stage?
    I have a wide image that extends past my movies stage size so when I preview my movie the image is visible. How do I mask out anything that extends past my movies window size? I believe I can create a layer named "mask" and place it above all other layers, but I forget how to make the mask. Any help is appreciated.
    How to Fade a Graphic
    I have a graphic element (some type) and I want it to fade from 0% to 100%. In older versions of Flash I could just select the symbol and then set it's alpha value to 0%, move a few keyframes and then set the alpha to 100%. Voila! but now it doesn't seem to work that way. How can I do this in CS5?

    Ned, it says 24 fps which means there is 24 frames per second so each 24 frames is 1 second.

    1 You can create your character as a movieclip and copy/paste that movieclip from one file to another. 2. One way to create a movieclip is to copy all the frame of the animation's timeline (select them all, right click the selection, choose Copy Frames), then create a new movieclip symbol (Insert -> New Symbol...etc) right click on its only keyframe and chhose Paste Frames.  THat will put all the layers and frames you copied into the movieclip The only way to come close to being certain about the timing of you animation is to use code to keep track of the time, something like getTimer()..  The frame rate that a file plays at is not a reliable means of dictating the time it takes due to a variety of factors which include the amount of content you are trying to process and performance limits of the user's machine.

  • Boot with Startup CD plus simple backup?

    Is it possible to reboot to a formatted iMac with just the original 10.6 startup
    cd plus a simple backup (SilverKeeper) of library, system, applications and users?  Now using 10.6.8.

    Gordon McGilvray wrote:

    cd...
    Yes you hold c and it boots off the installer disk that came with your comptuer or the OS X version you upgraded with.
    You can also install OS X onto a external drive provided it's formatted HFS+Journaled in Disk Utility.
    Gordon McGilvray wrote:

    Ok, you don't need to boot from the installer disk, all it does is install OS X and perform some disk repairs and reformatting. You go this route if you have to rebuild OS X completely, or reinstall it over the previous OS X to solve issues. Are you having a issue of some sort?
    We could use some more information why,
    What you seem to want to do is CLONE your boot drive to a Disk Utility > HFS+ journaled formatted (self powered) external drive.
    You can do this with the  free (donations accepted) Carbon Copy Cloner, which clones and makes the external drive "bootable"
    When your done cloning, the external clone is hold option bootable which you select the external clone to boot from.
    CCC only does OS X, no bootcamp or filevaulted drives.
    Once you have a clone, it can be updated much faster for small changes, the first clone takes longer as everything is copied.
    Only use one drive for a clone, it's a good idea to have two drives with two clones rotated every couple of weeks, updated daily with the auto-updte feature.
    This way if somethng goes bad, at least you can go back a week or two and recover by option booting off the older clone.
    More hardware redundancy also protects your data from hardware failure. Store a clone off site for any potential fire, theft etc.

  • Simple performance question

    Simple performance question. the simplest way possible, assume
    I have a int[][][][][] matrix, and a boolean add. The array is several dimensions long.
    When add is true, I must add a constant value to each element in the array.
    When add is false, I must subtract a constant value to each element in the array.
    Assume this is very hot code, i.e. it is called very often. How expensive is the condition checking? I present the two scenarios.
    private void process(){
    for (int i=0;i<dimension1;i++)
    for (int ii=0;ii<dimension1;ii++)
      for (int iii=0;iii<dimension1;iii++)
        for (int iiii=0;iiii<dimension1;iiii++)
             if (add)
             matrix[i][ii][iii][...]  += constant;
             else
             matrix[i][ii][iii][...]  -= constant;
    private void process(){
      if (add)
    for (int i=0;i<dimension1;i++)
    for (int ii=0;ii<dimension1;ii++)
      for (int iii=0;iii<dimension1;iii++)
        for (int iiii=0;iiii<dimension1;iiii++)
             matrix[i][ii][iii][...]  += constant;
    else
    for (int i=0;i<dimension1;i++)
    for (int ii=0;ii<dimension1;ii++)
      for (int iii=0;iii<dimension1;iii++)
        for (int iiii=0;iiii<dimension1;iiii++)
           matrix[i][ii][iii][...]  -= constant;
    }Is the second scenario worth a significant performance boost? Without understanding how the compilers generates executable code, it seems that in the first case, n^d conditions are checked, whereas in the second, only 1. It is however, less elegant, but I am willing to do it for a significant improvement.

    erjoalgo wrote:
    I guess my real question is, will the compiler optimize the condition check out when it realizes the boolean value will not change through these iterations, and if it does not, is it worth doing that micro optimization?Almost certainly not; the main reason being that
    matrix[i][ii][iii][...]  +/-= constantis liable to take many times longer than the condition check, and you can't avoid it. That said, Mel's suggestion is probably the best.
    but I will follow amickr advice and not worry about it.Good idea. Saves you getting flamed with all the quotes about premature optimization.

  • Wanted: Just A Simple Backup That Regularly Saves Latest Files

    Greetings:
    Subject line says it all. I'm just looking for a simple backup program that will hourly backup to my external hard drive and flash drive just the latest documents I'm working on in my User folder without having a whole duplicate of that folder on those disks. Maybe the idea's so basic it's overlooked but all my searching can't find any backup software along these lines. I've been told on MacWorld forum it might be possible to use Spotlight and Automation to search and save the latest files but they can't offer any clue how. I'd really be appreciative for any ideas!
    Thanks

  • Packup - a simple backup/restore/migration script for Pacman

    I have seen numerous posts on the forums asking for an easy way to backup and restore installed software for purposes of backup, migration or simply for convenience. Packup attempts to fill this void. Simply put, Packup is an ncurses wrapper for Pacman which provides a simple backup/restore/migration system for Arch. Don't believe me? Try it for yourself!

  • Simple backup - sync two folders

    I want to create a very simple backup process for a folder (with subfolders) to an identically named folder on an external drive.
    Right now I am just copying the folder with automator - but it takes several minutes as it writes each and every files regardless of whether it is new or not..
    Can I get it to sync the folders so that it only copies over new (or modified) files?
    I did find an action to do this in the apple downloads but it required Leopard.
    thanks

    Might try one of these instead...

  • A few simple Logic questions...please help.

    I have a few probably simple Logic questions, that are nonetheless frustrating me, wondering if someone could help me out.
    1. I run Logic 8, all of the sounds that came with logic seem to work except organ sounds. I can't trigger any organ sounds (MIDI) on Logic, they won't play. I have a Yamaha Motif as my midi controller.
    Any idea why?
    2. I've starting running into a situation where I will record a MIDI track, the notes are recorded but they won't playback. The only track effected is the one that was just recorded. All other midi tracks playback.
    I have to cut the track, usually go out of Logic and back in, re record for it to playback properly. Any idea why this may be happening?
    3. How important is it to update to Logic 9. Are there any disadvantages down the road if I don't upgrade. If I purchase the $200 upgrade, do I get a package of discs and material, or it just a web download.
    Any help is appreciated!

    you titled "simple quick question"...

    a) the TermsOfUse of the iTS don't allow any processing of purchased files, these are "copy protected"..
    b) iM has a voice-over function..
    c) iM is a video-edit app.. easy to use... just learn to handle it...
    d) iM allows to "extract" audio (=muting the original audio, adding your own..)
    e) to learn iM, spend some time here: http://www.apple.com/ilife/tutorials/imovie/index.html
    f) use pencil and paper first! WRITE and scribble, what shall happen when in your movie/parody... make a script, draw a storyboard .. THEN launch iM.. in other words: think first, then edit.. iM is just a tool, it does not "create"... Picasso needed a papertowel and half a stencil to create art....
    g) to get comfortable with iM, start with your own, small, short (3min!) project... import some stills, edit them, add a funny voice-over, add sounds, add music... good? make a bigger one...

  • Help with simple OS upgrade and backup questions for a dumb old previous PC user...?

    Ok...have mercy on me, please...
    I am not completely dumb, I know typical board etiquette, and I have searched for various answers (and found many)...but I just want to confirm my personal "research" and get all of this clear up before I proceed with this insanity.  I know I could probably search more, but this is taking hours, because of all my various questions, one leads to 10 more...
    I have an iMac with Mac OS X Version 10.5.8 (which, though not mentioned anywhere?...is apparently "Leopard", right?  Told you I was dumb...)
    Processor:  3.06 GHz Intel Core 2 Duo
    Memory: 2 GB 800 MHz DDR2 SDRAM
    My main goal:  install an app that was in the Mac App store.
    However, with Leopard, I can't access the Mac App store with Leopard, apparently. 
    I click on the Mac App store, and up pops up a Lion advertisement...telling me I should upgrade.  Ok, fine...probably a good idea, anyway...
    But how do you upgrade to Lion?  Apparently through the Mac App store!
    The web-redirects on the Apple site are amusing...taking me on an endless cycle...purchase Lion in the app store...click..."you need to upgrade to Lion"...OK...click..."you need Lion at the app store"...OK...click..."you need to upgrade to Lion to get to the app store"....etc.
    OK...fine...google searches...ahh, I need to upgrade to Snow Leopard first, apparently!  Yes?
    (Maybe the Apple redirects should detect that I have Leopard, and direct me to a screen that explains that I must upgrade to Snow Leopard...and then Lion!  Do you hear that, Apple?  Thanks.)
    Anyway...so here's my plan:
    1) Upgrade to Snow Leopard
    2) Access the Mac app store
    3) Upgrade to Lion
    Question A:  With my iMac (specs above), is it really advisable for me to do this?  Can my computer really handle Lion?  It seems I barely meet the minimum with my intel core 2 Duo and 2 GB ram...yes?  Is this a dumb idea, even if "OK"?  I know that "minimum requirements" on a PC often meant:  "Well, it will work...but it will be slower than a snail and crash if you run 5 programs at the same time" (which I usually do...)  I don't want to upgrade if the "minimum" is really not enough. 
    Question B:  If the answer to A is "not a good idea", then  do I just need a new computer (i.e. better processor)?  Or do I need more Ram?  And can I add Ram to this computer, and is it relatively easy?  I have added Ram to PCs tons of times, and you always have to determine type of Ram for your board, make sure they "match", or whatever, and then open up the machine and install.  Kind of a pain, but once I have the "right" type of Ram, opening the CPU and installing is within my abilities.  Will it be harder for a Mac?
    = = =
    Next:
    When upgrading an OS on a Windows, you pretty much format the harddrive and start all over.  Back in the day I was a PC user, there wasn't really a "great" way to back up programs and files, so this was a nightmare.  You could NOT just back-up software.  You typically had to re-purchase and install it all from scratch.  Is this the same with Macs?  Furthermore, personal files were scattered all over the hard-drive for the individual software...so trying to back all that up to get it back on the new system = nightmare!  I hate PCs.
    Anyway...so, my iMac has Time Machine.  I am pretty ignorant about this, and based on my previous PC backup program nightmares, I have a distrust for it...and don't really understand how it works.  But in any event, my external drive crashed a few months ago, and I haven't replaced it, yet.  So, I am replacing it soon and will get Time Machine back up and running...setting it up again, etc...leading to question C...
    Question C: When upgrading from Leopard to Snow Leopard to Lion, what is the best way to ensure I keep all my programs and files.  My wife and I both access the computer, so two user accounts.  Does Time Machine really do a good job backing up everything and all things?  Is it just a matter of upgrade to Snow Leopard...then immediately to Lion...and then some sort of "Restore" from Time Machine?  Anything for me to "watch out for"...or to do when I buy a new external hard-drive and setup up Time Machine for the first time on it, in order to make this work well?  Will I have to re-install all the various applications I have installed on this thing?  (like with PCs?)
    Thanks for any sincere help.

    Apple has discontinued support for 10.5, it's a plaque of our platform that Apple only supports the last two operating systems in circulation.
    Where as on Windows you can run the same OS version for 10 years and get updates free (if not stolen), on a Mac we get one year, two tops now and if you don't upgrade and break all your third party software and hardware drivers in the process, then your denied security updates.
    On top of that, the OS X upgrades tend to break your older hardware too, or slow it down so much that it drives you to want to buy newer hardware.
    It's funny Apple places the AppStore on your OS X version along with iTunes and Safari updates, but then doens't supply necessary security updates, your machine may be compromised and here you enter vital credit card info, banking  etc. thinking you have a secure machine.
    My advice, since that's a 10.5 era Mac, is to upgrade to 10.6.3 via this disk, then use Software Update until clear. You'll get security updates and your present installed 10.5 software will work in 10.6 using Rosetta.
    http://store.apple.com/us/product/MC573Z/A
    Rosetta is not avaialble in 10.7 so it could be a lot of your software will no longer function
    http://roaringapps.com/apps:table
    I don't see the sense in you buying all new software for a machine that's at it's end of life stage.
    You can buy software in the AppStore with 10.6.
    Question A:  With my iMac (specs above), is it really advisable for me to do this?  Can my computer really handle Lion?  It seems I barely meet the minimum with my intel core 2 Duo and 2 GB ram...yes?
    You will need to buy 4GB of RAM to run Lion well, the 2GB is just a bare minimum, and your processor is a bit dated.
    Lion 10.7 is certainly slower than Snow Leopard 10.6, in fact so many wanted to go back to Snow Leopard and one of the resons was Lion was slow.
    So I wrote a User Tip, here, but the Tips were implemented only recently.

    RAM is easy, you can buy it at Otherworld Computing or Crucial.com and install it yourself, there is a little door under the monitor.

    Mac'soperaing system is seperate, it can be replaced or upgraded indepentantly of programs or user accounts on the machine.
    There are some programs that install a kernel extension file at boot into OS X, those get knocked out, but those can be replaced with a new install of the software.
    You should always backup your users files as those can't be repalced.

    Question C: When upgrading from Leopard to Snow Leopard to Lion, what is the best way to ensure I keep all my programs and files.
    OS X upgrades dont' affect User accounts but they can have a affect on programs installed, which most of your 10.5 programs likely will no longer work in 10.7
    However they will (with a slight update) work in 10.6 just like before.
    You need to backup regardless, I suggest a manual backup of users files to a storage drive, a 10.5 clone on another drive, the your ready to upgrade to 10.6
    10.5 to 10.6 upgrade is rather painless, also 10.6 gives accelerated video drivers, so your machine will appear faster.
    However once you install 10.7, you will slow down.
    Does Time Machine really do a good job backing up everything and all things? 
    No, you shouldn't rely upon TM, have a multiple backup stragedy, TM files are hard to access directly.
    Is it just a matter of upgrade to Snow Leopard...then immediately to Lion...and then some sort of "Restore" from Time Machine?
    No need to restore, OS X upgrades and leaves everything else in place, just some programs (with 10.6) or a lot (with 10.7) when you try to launch them they will fail.
    Also when you connect TM it will do a substancial change to reflect the new boot drive.
    If you were using TM as a "storage drive" thinking you can use the archived versions later, that wil change upon the new OS X  upgrade.
    But in any event, my external drive crashed a few months ago, and I haven't replaced it, yet.  So, I am replacing it soon and will get Time Machine back up and running...setting it up again, etc...leading to question C..
    You need not only TM drive, but a bootable clone and user files on a storage drive.

    Will I have to re-install all the various applications I have installed on this thing?  (like with PCs?)
    No, depending upon what OS X version you stop at depends how many programs no longer work.
    You will have to buy a lot of new or upgrade versions with 10.7, not so with 10.6 only updates mostly because of Rosetta on 10.6 and not on 10.7
    My opinion, since that machine is a bit dated, is to upgrade to 10.6, Software update to 10.6.8, and stay there.
    Later on 10.8 is being released after this summer, you may want to consider getting a new machine with 10.8 a few months later to ensure all the bugs are worked out of it.
    Your not a comptuer savvy person, you like most Apple users expect your machine to "just work" I think going to 10.7 will be a bad experience for you.
    10.6.8 will server your needs until 10.8 is released and on new hardware where Apple will hold your hand for free for three months, 3 years with AppleCare.
    Your not a "OS X upgrader type of a person" and Apple needs to get of thier collective assets and pay better attention to it's most common users.

  • Simple optical disk backup question

    i want to backup some files to an optical disk so i can reinstall the op sys. how best to do this. also one of the files i am interested in is the bookmarks of my browser(safari) where is this located is it accessable?
    thanks
    tencups

    tencups:
    Your Safari bookmarks are located: Home > Library > Safari. If you are backing up data files they can be simply dragged and dropped. Depending on the size of your Users/Home folder you can probably just copy the whole thing.
    Good luck.

  • Please help me with some backup questions....

    After suffering through two hard drive failures (not my main drive, fortunately), and being frustrated with trying to keep everything backed up, I'm taking a fresh approach to everything and I plan to do the following:
    1.  Purchase a new, 2 TB hard drive (enterprise class - Can you guys recommend a reliable one?) and clone my existing main hard drive to it.
    2.  Purchase a second identical drive and install it in bay #2.
    3.  Likely purchase G-Technology's G-Safe with Raid 1 capability.  Likely 3 TB just cause.
    4.  I'll keep my current 1 TB Hitachi Deskstar in the 3rd bay.  It serves only my Sonos music system.  (I wanted a separate drive for that so my regular drives weren't always running.)
    So far so good.  I plan on putting all my files on the one main 2 TB drive.  (Formerly roughly 500 GB of music was on a separate internal drive, the one that's died twice now. Seagate Barracuda FYI.)  I'll then clone the main drive to the identical drive in the 2nd bay and make it bootable as well.  That's backup #1 and I plan on having it also updated regularly.  (Incrementally, not a complete erase and rewrite, but still keeping it bootable.)  I'll then hook up the Raid 1 drive and clone the main hard drive to that as well, also making it bootable.  That will give me backup #2 and #3 (through mirroring).  These drives will be backed up less often and when not being used, will be stored in a fire proof safe in the garage.  So far so good, I think.
    What I'm stuck on is what software to use for doing the cloning and more importantly, the backups.
    For the cloning, I understand I can simply use the Restore function in the Disk Utility.  Is this correct?  Or am I better off using SuperDuper or Carbon Copy Cloner?  If so, which one?  And why?
    For the regular backups, I have been using Retrospect but frankly, I'm less than impressed with their interface and I've never liked the fact that even if the backups aren't compressed, I can't see the files unless I do so through Retrospect.  I can't just go to the backup drive and view the files.  They're all hidden in the one Retrospect icon.  So, I'm considering the following:
    Time Machine:  However, I was less than impressed with it in the past as it seemed to completely fill whatever drive I pointed it to and then it would fail to backup.  I never could figure it out that well. 
    SuperDuper:  I was just checking them out and it seems that it's not only a good cloner, but will also then keep that clone up to date and bootable on a regular basis.  It really sounds like it's what I need.  And the screen shots I saw on their site seem pretty well thought out and explain a lot.
    Carbon Copy Cloner:  I know this app has been around for a long time, though I've never used it.  I'm presuming it's good for cloning a drive onto a larger drive, just as SuperDuper is, but can it do scheduled backups of that clone like SuperDuper can? 
    And in all cases, I want to keep both the second internal drive and the external RAID drives backed up from their original clonings.  Can any of these programs handle ongoing backups to two or more destinations from the same source? 
    And finally, a last question or two:
    To repeat my first question, who makes a really reliable enterprise class drive? 
    And has anyone had any experience with G-Technology's G-Safe with RAID 1? 
    Thanks much for all your help. 
    Oh, here's my system:  Mac Pro tower, 2008 2.8 GHz, 10 GB ram.  Dual Intel processors.  Currently 10.5.8, soon to be 10.6.8.

    Hitachi and Seagate both make enterprise class drives. Just visit their websites to find models.

    I don't know what your desires are for backup redundancy, but I would create a two drive mirrored RAID for your main backup. This could consist of two identical hard drives mounted in your Mac Pro's slots (this is what I do.) Or you could purchase a two-drive external case and use Firewire. (I also do this.) Drive size should be determined by how large a drive(s) you are backing up and if you plan to use Time Machine. TM's backup device must be at least twice the size of the drive(s) it backs up.

    If you are running Lion then do not use SuperDuper. It has not yet been updated for reliable use with Lion and cannot handle Lion's Recovery HD. Carbon Copy Cloner's recent beta release would be a good choice as would Synk Pro from Decimus, or Tri-Backup.  All of these will clone a drive as well as perform scheduled backups/updates of a clone. But only CCC properly deals with Lion's Recovery HD at this time. All of these make essentially file by file copies from the source to the destination. One can easily restore a file or a few items without needing to use the backup utility since everything on the backup is accessible through the Finder.
    TM is not able to create a bootable clone. It is an archival backup utility intended for home users needing basic, automatic, and simple to use backup software. Restoring software from a TM backup can only be done through the TM application.
