If I back up on my external hard drive and then delete files on my computer, those files will remain on my external hard drive even after future back ups when those files aren't on my computer?

I am backing up my macbook pro on an external harddrive because I have run out of space on it.  I am wondering if when I do a backup and then delete those files from my computer, during the next backup, those files will still be availavle on the external harddrive or will they be deleted because they are no longer on my computer.  Confusing I know but I'm sure there is a simple answer to it!

Its good to have both, a time machine backup, AND a second cloned HD.
If your HD ever dies on you, you can in a matter of 20 mins, install the old HD and be up and running again quickly.
Its extremely important to have MULTIPLE backups, so many people have been so upset at losing massive amounts of data, because they "had a backup HD" for their data, but when that died etc, its gone.
1 backup is never enough, and the data on your computer "doesnt count" as a backup.

  • My goal is to backup my pictures and movies and then delete them from my computer to open up more space. What's the best way to do this?

    Let's say I let time machine backup my computer, then I delete most of my pictures (that are now backed up) to make room on my laptop's hard drive. The next time Time Machine backs up my computer will it overwrite the old backup with what it currently sees on my computer? Will it loose all of those pictures, because they're no longer on my laptop?

    Yes eventually or sooner by large changes to your boot drive.

    When you make a move to an external hard drive, it's really an all or none proposition. You can move the iTunes music folder to the EHD, then change your iTunes preferences to point iTunes to the iT music folder on the EHD. The following link will explain things in detail, as there is a little more involved then simply moving a few files.

    As long as the apps and ibooks are still available in the store, and you use the same iTunes account as you originally used to buy them, then you should be able to re-download them for free : http://support.apple.com/kb/HT2519

I never send anything from there but I have the same email in yahoo but delete them and they still show up in apple mail from day one how do I get rid of these once and for all.Please help

    I am soooooooooooo confused now.  Ok, if you are having problems with Yahoo Mail and Gmail but you do not use Apple's Mail you need to do the following:
    1 - Post in Yahoo's Mail forums and/or contact their tech support.
    2 - Post in Gmails forums and/or contact their tech support.
    Neither of the above are Apple's products.

  • Is it possible to save an iPhone back up and access the files later if needed?  I have a string of text sms and iMessages that I would like to save and then delete them from my phone.  Is this possible?

    I have a string of text sms and iMessages that I would like to save and then delete them from my phone, but gain access to them later if I need them.  I prefer to have the string with the date/time stamp vs copying and pasting into a doc or text file.  Is this possible?

    Not unless you buy an app that accesses data from an iTunes backup.  Check in the app store.

  • Does Time Machine make back-ups when nobody is logged on?

    Hello,
    Does Time Machine make back-ups when nobody is logged on and does it continue to back-up when I log off?
    I'm using an directly connected external hard drive to back-up my data with Time Machine, the back-ups are encrypted.
    Thanks in advance.

    I had the same problem with Time Machine and solved it by enabling "Enable Power Nap" in Energy Saver:
    System Preferences...
    Energy Saver
    Restore Defaults
    Check "Enable Power Nap: While sleeping, your Mac can back up using Time Machine and periodically check for new email, calendar, and other iCloud updates."

    EMERGENCY!!!!!!!!
    IS THERE ANY WAY TO RETREIVE AN ACCIDENTALLY DELETED BACK UP FROM MY TIME MACHINE DRIVE????
    In other words, I emptied out a folder on my main MAC to make space and the next subsequent backup backed up the EMPTY FOLDER and then deleted the "old backup" that actually contained the contents of the very important folder.
    Now only the emptied folder exists on my MAC and in the two backups on my Time machine backup drive.
    This was clearly a big mistake on my part not realizing that the "old backup" being deleted by Time Machine would include backed up files that I had no intention of getting rid of....
    What can I do now?
    Is DATA RETREIVAL even an option?
    I am sure that the Folder of files that I need are on the most recently deleted "OLD BACKUP" but how do I get to this, if even possible?????
    Super desperate situation here...

    It may be possible to recover some of the data, if it hasn't been overwritten, but it won't be cheap or easy. 
    You've posted in the Time Capsule forum, but you mention a "backup drive."  If your backups are on a Time Capsule's internal HD, instead of an external HD, it's even worse.
    See Data Recovery.
    Good luck.

    I tried to rename a file, it gave me an error message (can't remember the number - 43??) and then the file disappeared from the original folder. When I do a search, the file comes up under the new name, but it does not show a path, and even though preview shows the contents, I can't open the document (Powerpoint) and I can't move the document. I tried "Copy" and paste but it doesn't work. I tried "Share" with Airdrop and iChat, but the file is inaccessible. When i try to rename the file, it says the filename is too long.
    When I try to open it, it says the alias is not good, and asks if I want to fix the alias. I'm afraid to do that and lose all access to this document.
    Right now, it feels like a ghost document - it is on the computer intact, but it is in an undisclosed location and inaccessible.
    Please help!!

    I was able to resolve this by repairing permissions, even though no permissions error was listed specifically for that file.
    I could also have recovered it through Time Machine, but I'm interested in knowing how not to have this happen again!
    I was afraid of rebooting and possibly losing track even of the ghost.
    I did not try EasyFind - I'll keep that in mind next time.
    Thanks for all the comments.

  • Trying to save a new document and then "The file "lyrics project.pages-tef" couldn't be opened."

    As the title says...  Open Pages, Create new document, click Save, the dialog box comes up, I give it a name and select the Desktop as the destination, click OK, the dialog box disappears for about a second and then I get the above message.
    No way to save the doc.  I even copied the text, opened another new document, Renamed it and tried to save and same results.  It's a very simple document saved in Pages format, without involving iCloud so it should be as easy as it gets.  On top of that, I just want to Save.  Why is it trying to Open something???
    I ended up having to copy the text into an email and sending it to myself in order to copy it into a SimpleText file.
    Any ideas on what might have been going wrong?
    MacBook Pro 13, OSX 10.8.2, current version of Pages.
    Thanks much.
    Bo

    That is the iCloud version of the document as I understand it. There is a version saved on the Net for iCloud to be shared and a local version on your hard drive. One of those is currently inaccessible.

  • I backed up a video to icloud and then deleted it from my iPhone but have recently backed up again - will my video still be in icloud?

    I backed up my iPhone to the Cloud a few weeks ago and then deleted a video from my iPhone.  I have since backed up my iPhone again....will my video still be in the iCloud? Does the iCloud when restoring, overwrite existing data on my phone?

    If the latest backup does not include the video, then it won't be restored if you restore from that backup.  Technically, there should be around 3 backups maintained in icloud, but many users find that they have one one choice to make (the latest backup) when they perform a restore from icloud. 
    Like photos, video should always be synced to a computer for archiving.  If you've done that, then you should be able to find it on your computer.

  • TS3992 If I back up pictures from the camera roll on my iPad to iCloud and then delete the pictures off my iPad will the next back up to iCloud erase those picutres from iCloud?

    If I back up pictures from the camera roll on my iPad to iCloud and then delete the pictures off my iPad will the next back up to iCloud erase those picutres from iCloud? or will all pictures remain in iCloud?

    They will be erased.  The backup only includes the data (and photos) on the iPad at the time of the backup.  To keep your photos permanently, import them to your computer as explained here before deleting them: http://support.apple.com/kb/HT4083.

As for the version, when I open pages from my apps and click 'about' it says version 5.1? And when I open the document it just goes grey and kind of blinks and doesnt open? No error message or any indication of why it will not open now when I for sure have opened it in the past! Andddd for the OS X I think it is 10.9.1 ??

  • HT1311 To create a new apple ID, if I sign out of the current Apple ID account, and then sign in with a newly created account, will I lose any songs or apps on my phone or computer that were downloaded from the old apple ID?

    To create a new apple ID, if I sign out of the current Apple ID account, and then sign in with a newly created account, will I lose any songs or apps on my Iphone and Macbook Pro computer that were downloaded from the old apple ID?

    No, you will not loose anything.  However, if you ever need to update any of that previously purchased content, or re-download it, you will have to use the older AppleID.  Purchases are permanently tied to the AppleID you use when making the purchase.

  • How do I find a previous windows version. It's telling me to copy files and then delete old version.

    When I got on my laptop today, I saw that there was a message from HP Support Assistant. It says that I have an older versions of windows and that the previous versions of windows was saved in a folder c:\windows.old. it says that the folder is very large and it recommends me coping any old files I want to keep and then delete the Windows.old to free up more disk space. It has a help column that says, "How do I backup my files from Window.old? When I do what it tells me to do, I can't find it. Could someone please help me? Thanks you.

    Looks like a new OS has been installed/re-installed. Do you want to keep Windows.old folder for just in case? Otherwise you can delete it using the following instructions:
