Time Machine and renamed files

Hi. Stupid question time. External HD for TM, set up for once a week.
I have multiple gigs of video files, for which I'm considering changing my naming convention. If I rename the files but don't make any other changes, will Time Machine back them up as new files next time? As in, the backup HD would have duplicate full-size files, one with the old name in an old backup and one with the new in the new backup.
I suspect the answer is yes, but I thought I'd ask. Space is not an issue at the moment, but obviously if I made a habit of doing this it would be. (In which case, I'd hope to do it with one re-backup and move forward.)

No such thing (only stupid answers.)

Why? Why not let Time Machine work as designed, to protect you best, by doing hourly backups? Since all but one per day are deleted after 24 hours, they don't take up much space, but can really save your bacon if you accidentally change or delete the wrong file (I occasionally get distracted and click "Save" when I mean to click "Save As," for example).

The same thing will happen if you move files or folders; they'll be backed-up again. If you move a folder, all the sub-folders and files inside it will also be backed-up again. But of course only once; if they're not changed, moved, or renamed, they're not backed-up again.
If space does become a problem, you can delete all the backups that were made from the old location, per #12 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

  • I want to use my 1TB Seagate Hard drive for time machine and transferring files from Mac to PC.

    For about a year I've been using my 1TB external hard drive for only time machine. To be honest, it wasn't until today that I tried to connect my hard drive to a PC and realize it isn't compatible. I read about partitioning the hard drive so that it can work both for time machine and transferring files between pc and mac. I'm not what you would call tech savvy, so I was wondering if I can get some advice on how to do this.
    Thanks in advance.

    To do it, you have to partition the hard disk, so you will have one partition for Time Machine and another one to store files and use them in a PC and Mac. To create the partition, follow these steps > http://pondini.org/OSX/DU3.html
    In order to read and write in the external disk on the PC, you have to select "MS-DOS (FAT)" as "Format". If you choose any other option, the PC won't be able to read your external disk. Apart from that, note that you can't use files bigger than 4 GB with FAT. If you want to use the external disk with files bigger than 4 GB, you have to format your new partition in exFAT, and you have to do it on a PC

  • External Drive Time Machine and other files

    I want to use an external drive for time machine and storing other files.  Does time machine need the external drive exclusively or can one also put other files on the drive?

    A backup strategy is one of individual choice.  By having more than on HDD for your data, you are distributing the risk
    I have 5 external HDDs.  One is dedicated to Time Machine, the others have data that simply takes up too much room on the internal drive in the MBP (mostly video).  Some of the data that I have on these HDDs is redundant copies of what I have on the MBP and in Time Machine.  This is data that is important to me.  This may seem excessive but I would argue not.
    Ex: my iTunes is on the internal HHD, Time Machine and also on my secondary MBP (and the iPod).  That for me is important an I do not want to lose it.
    I have seen too many instances on this forum where individuals have lost data without adequate backups looking for answers on how to retrieve that information only to be disappointed.  Please don't let that happen to you.  Given enough time, ALL HDDs will fail!
    Ciao.

  • Time machine and hidden files

    Hi all
    Apples old Backup software didnt backup hidden files (which i think really *****), but the question is does Time Machine backup hidden files as well?

    The best way I have found to restore hidden files using Time Machine is to download the "HiddenFiles" widget from the widgets downloads here:
    http://www.apple.com/downloads/dashboard/developer/hiddenfiles.html
    Once you have hidden files enabled, then they also show up in Time Machine, and appear to restore just as easily as normal files

  • Encrypted Time Machine and Other Files

    Hello. Is it possible to store other files on an encrypted Time Machine backup drive? I'm trying to find a place to store files such as raw images etc that I don't want to store on my MacBook but want to store on an external drive. I'm trying to avoid the need to purchase another hard drive as there is plenty of space available on the external drive I use for my Time Machine backups.
    The external drive cannot be paritioned to accomplish this as Time Machine encryption only works if the drive has a single partion.

  • Time machine and network file server

    Hi,
    Is it possible to set up the time machine to a network file server which my macbook is able to see and use? Right now, time machine is limited to be used with a delicated external HD or another Mac...
    It would be convenient to share files between my 1st mac and other windows PCs.

    I believe I can do a work around by simply sharing my External HD so that that can happen. It's just very awkward to navigate to that shared drive each time we access it. If I had separate backup HDs for each MAC, I think I could use the TC as a media server (at least that's what I get from the marketing material here ).
    You might want to try one of the workarounds in #Q3 of Using Time Machine with a Time Capsule.
    Have you ever used Time Machine Editor? Is it worth downloading and using?
    It's not recommended;  Time Machine usually works best the way it was designed.  See Time Machine - Frequently Asked Question #13.

  • Time Machine and iWeb file

    I have used time machine for weeks. Yesterday I deleted an iWeb file I was preparing for publishing and decided I wanted to do it differently. Now I want to restore the iWeb file I had 2 days ago.
    How do I find that file in Time Machine? I have no idea where it resides on my HD either.

    quit iweb and restore the contents of the directory /users/username/library/application support/iweb.

  • Itunes, Time machine and 4Gb  files. Getting a FAT32 error.

    Using Itunes to purchase a movie in 1080.
    Something I have done many times before...
    I have a remote itunes disk, it is a Apple 3Tb Time Capsule.
    Now I get a can't download the file to a FAT32 file system error that stops me dead... the error I get is generated by itunes... I have many >4Gb files on the Time Capsule and they are no problem.
    Any insight? Thanks

    Hi Damballa,
    Time Machine's backup folder can coexist together with other files, however it would most likely be better practice to partition the drive into 2 parts in disk utility. 1 part for time machine, the other for your audio files. That way, it keeps them separate from each other, which is always better imo, especially for time machine.
    OR, since you have a Mac Pro, put those 4 HD slots to good use! Buy 2 HDs!
    They are so affordable right now. I'm not sure your main drive size, but Western Digital 640GB drives are simply awesome: speed, price, size. $75 for what you get..is sick.

    If I were you, use the WD 640s as your main drive, great boot times.

  • Shared Time Machine and duplicated files?

    I have a new MBP (running Lion) and an older MacBook (running Leopard).  I'd like both to run Time Machine to a shared external hard drive which I think I've worked out.  My question is whether or not TM will store duplicate versions of the same files (particularly photos, videos, etc.) on the external hard drive, thus using up the EHD capacity more quickly, or will one file be saved and just recognized as being on both computers by TM. 
    Any ideas on this?  Ideally I'd like to take a good amount of files off the old MacBook so my wife can still use it and it will run a little smoother since it's hard drive is pretty close to maxed out now. 

    The backups will be separate. Identical files will be duplicated.

  • Time machine and extra files?

    Hey yo,
    If I get an extra Hd to use for Time Machine can I also use that Hd to store and access say Audio files for Pro Tools? Im looking into getting an additional HD to store a image of my Hd for backup purposes and figure while Im at it I could just get a larger HD and store my audio files for PT to it. Since the logic is that Pro Tools runs faster and better if you put your audio files on another HD that is not you boot hd. Can I do this?

  • Can you back up Time Machine and store files as well?

    Ive been reading on and on about Time Campsule, and in the early stages of it has been mentioned if you use this as a back up for your laptop (Time machine) to not use it as a storing place for files?
    For example,
    I have two macbook pro's.  I want to store time machine of both of my laptops onto time capsule, so if my hard drive dies, or laptop is stolen I can just restore from time capsule.  (That might be a question in itself, If my laptop is stolen can I restore from a back up in time capsule onto a new macbook pro?)
    But I also would like to store my photo's, songs, doc's etc.. onto time capsule as a stoarge drive, so I can just pull the files from each laptop and vice versa.  I was hearing if your going to be using time capsuel as a storage unit and putting your time machine to it as well, its not a good idea because the hard drive will fail? Is this still the case?

    I understand having all your data on a drive is not a back up. (I was wanting to use time capsule as a stoage drive "not a backup" along with time machine "to back up the whole computer.")  I guess what im trying to say is, can time capsule store files on it as well as use time machine? 
    So if time machine will take up all your space on your time capsule, will it delete the older back ups of time machine to create new space for the new backups? The hard drive in total is only 500gb of each mabook, that would be a total of 1TB.

    Be sure you're signed-on as the user who "owns" the backups.
    If that doesn't help, try a +*Repair Disk+* on your backups, per #A5 of the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.

  • Time Machine and .dmg files

    Ok, this isn't technically a TM issue, but I'm posting in here as it directly affects TM backups.
    I'm running OS X 10.5.2, and whenever I mount an encrypted disk image and open the disk image folder, the modified date of the disk image changes. This causes TM to back it up again.
    This happens even if I don't actually run any of the files in the disk image, or change anything in it. So, my question is how (if) this can be stopped. Perhaps by setting the image to Read Only?
    All help appreciated. I'm relatively new to MAC (switched from Windows a few weeks ago and loving it!) so any assistance will need to be reasonably detailed.

    Yes, that will always happen. If you use Parallels or VM Fusion and just run a VM the pseudo drive will post a modification date and any backup program will then backup the file. Same with any disk image file. To stop it you need to drag the file to the TM exclusion list. Any item in the exclusion list will be ignored during backup.

  • Using Time Machine and other uses on one drive

    I want to get the Iomega Prestige 500 GB USB 2.0 Desktop External Hard Drive 34270 to back up some files from a Tiger machine, and possibly from some Windows machines to, but I also want to be able to use it for Time Machine in the future.
    How do I format the drive for Time Machine? If I format it after I start putting files on, would the files be removed? If it's formatted for Time Machine, will it work with the Windows computers? If formatted for Time Machine, will I be able to use it for Time Machine AND regular file storage?

    Prepare the drive as follows:
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Set the number of partitions from the drop down menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Now, you cannot use a Mac formatted drive with Windows unless you install Windows software that enables this such as MediaFour's Mac Drive.
    If you format the drive FAT32 instead of Mac OS X Extended then you can use the drive on both the Mac and Windows without anything additional, but the drive will not be usable with Time Machine unless it's formatted Mac OS X Extended.
    Now, you can partition the drive so that one partition is formatted for OS X and the other for Windows, but to do that you must partition the drive using GUID instead of APM. The former is not compatible with Tiger or non-Intel Macs.
    Note that to use Time Machine you must upgrade to Leopard. TM is an incremental archiving backup program so your backup drive will need to be at least twice the capacity of the drive you will backup.
