Time Machine - change back-up exclusions

I changed from direct attached time machine drive to a NAS (LaCie) and succesfully completed a time machine back-up. Excluded in TM preferences were the appliccations folder and a movie file folder. After a few weeks, I decided to include the Applications folder (ie to be TM backedup) and changed the preferences accordingly, ie deleted App folder in TM options dialog box that was previously excluded. However, it now won't back-up the applications folder. I deleted the TM pref file but to no avail. Any ideas?

  • How do I know if time machine is backing up my apple mail? I need to have copies of all of my emails, so there I have a lot of mail files. I was told that if I change computers, that the mail files will all be on time machine. Is this true? Thanks, Dave

    Is there a way to verify  if time machine is backing up my apple mail?  I was told that if I change computers, that the mail files will all be on time machine and can be easily be put on a new computer using my time machine backups.  Is this true? Thanks, Dave

    Having deleted some Mail messages by mistake, I have had to recover them from TM. I can tell you that the recovery of mail messages will be done at the mailbox level. In my case it was half of the messages in a mailbox. So I recovered the complete mailbox from TM. Then I copied the messages from the recovered mailbox back into the mailbox I use in Mail. I hope that helps.
    Please be aware that TM is a backup application and not an archival application. What that means is that if your TM drive gets full, it will get rid of older files which could be mail messages to make space for newer backups. You might want to consider archiving your mail instead of using TM if you need to maintain your mail messages for extended periods of time.

  • Time machine not backing up new changes

    Time machine was working perfectly fine until this past weekend. Now, it seems like it's not recognizing any new changed on my hard drive. The time machine still runs successfully, but it just repeats the same back up over and over again. I've checked the logs in console (see below)
    Dec 15 00:35:25 localhost com.apple.backupd[6749]: Starting standard backup

    I've also downloaded Time Tracker and it says that things were fine till this weekend and then everything for the past couple of days have 0 bytes backed up. Any ideas what could be the problem? I haven't done anything special or changed anything besides install Google Chrome. The external hard drive I back up to may have been unplugged/plugged but not before it's unmounted or the computer is off. I don't think I unmounted while time machine was backing up, but if I did could this be the problem?

    Solved! Thanks for the swift replies! I didn't do a Verify Disk, but I did do a Verify Disk Permissions without restarting recently.
    Are you sure? Because +Verify Permissions+ doesn't do it. Only +*Verify Disk,+* or altering any partition on your boot drive.
    There are some 3rd-party disk repair/maintenance apps that use the same internal OSX routine as +*Repair Disk,+* so if you used one of them, you'd have the same problem.
    And by the way, there's no point to running +Verify Permissions+ -- you might as well just run +Repair Permissions.+
    I just restarted and Time Machine has in fact "caught up" with the most recent changes! Cheers Pondini.
    Oh, well, whatever it was, I'm glad it's fixed! And thanks for the star.

  • Time Machine changed my driver permissions - can't change back

    Hello,
    I've been using my external hard drive for about 6 months to backup my work, never had a problem.
    Today I mounted the drive, as usual, and a window came up asking me if I wanted to use it for time machine backup. I clicked OK, thinking I could backup my new work, then when I saw that I would have to format my drive, I decided it was not what I needed, since I have all my old work in it.
    So I de-selected my drive from the window where it asks which drive to be used for time machine, and turned TM off before doing any operations.
    Since then my hard disk has become "read-only"!! Luckily I haven't lost any of my work, but I am now unable to set the permission back to "read - write". The "Repair Disk Permissions" button is greyed out.. and if I do GetInfo, I can only see it is read only, but I have no option to change that.
    Any idea why time machine changed my settings before I even used it??
    How can I change it back?
    Thank you

    Not it all makes sense. I should go kill him.
    I rather suspect that TM is at fault. TM drives have to be formatted HFS and by what you describe it sounds like it started reformatting the drive when you stopped it.

  • How do I stop Time Machine from backing up Aperture thumbnails?

    Hi,
    My 2TB backup drive recently became full, and I became curious as to what was filling it up. I wrote a perl script to analyze the Time Machine backups, and I noticed that over 50% of my backup was filled with AP.Thumbnails and AP.Minis from the Aperture project directory. In particular, the AP.Thumbnails files in the backup consumed 737 GB of disk space!
    The problem with the thumbnails files is that they are a single file that contains all of the thumbnails for all of the 40,000 photos I have in Aperture and it is now 20gb in size. Every time I add a new file to Aperture, the thumbnail file changes, and I get a new 20gb of data added to my backup. I add photos often which means that most of my backups have 20gb of Aperture files (which are easy to rebuild and don't need to be backed up).
    I decided to try and stop Time Machine from backing up these files, and there seems to be no way of doing so (without telling Time Machine to skip backing up my entire Aperture project which I don't want to do). In Finder, you can do a "show package contents", but the Time Machine GUI doesn't allow this.
    I tried to tell Time Machine to exclude the files via the GUI, but Time Machine sees the Aperture Library as a single package and won't let me exclude individual files from within the package.
    I googled around, and found the attribute that Time Machine puts on files to exclude them from the backup. I used xattr to set the attributes:
    xattr -w com.apple.metadata:comapple_backupexcludeItem com.apple.backupd <filename>
    I also used this command on the iPhoto thumbnail files.
    I used spotlight to find all of the files with this attribute using this command:
    sudo mdfind "comapple_backupexcludeItem = 'com.apple.backupd'"
    This command returned the iPhoto files, but did not return the Aperture files.
    However, if I run "xattr" on the Aperture files, the attribute does exist!
    During my next time machine backup, the iPhoto files were skipped as I wanted them to be, but the Aperture thumbnails were backed up again
    I thought that maybe time machine was looking at the aperture package as an atomic unit, but iPhoto is stored as a package as well, and the attributes worked there on files inside the package.
    Does anyone have any idea why time machine is still backing up these files? Is there any way I can get around this?
    It seems to me to be an incredible oversight on Apple's part since both tools are Apple. The thumbnails files are very expensive to backup, and they are not necessary for backup since the are easy to rebuild from the original photos which are also backed up.
    Thanks,
    Ron

    No need to write your own script for that. there are a couple of already made nice GUI tools for this - TimeTracker http://www.charlessoft.com/ and BackupLoupe http://soma-zone.com/BackupLoupe/

    I don't have aperture but I think most people exclude the whole thing from TM backups and back it up separately. but if you want to exclude a subfolder in a package that's easy too. just select the package in finder, control-click on it and select "show package contents". in the resulting finder window drill to the folder you want to exclude and drag it to the TM exclusion list in TM system preferences->options.
    I googled around, and found the attribute that Time Machine puts on files to exclude them from the backup. I used xattr to set the attributes:
    xattr -w com.apple.metadata:comapple_backupexcludeItem com.apple.backupd <filename>
    I was not aware of this method for excluding stuff from TM backups. could you provide a link to where you found this?
    I also used this command on the iPhoto thumbnail files.
    I used spotlight to find all of the files with this attribute using this command:
    sudo mdfind "comapple_backupexcludeItem = 'com.apple.backupd'"
    This command returned the iPhoto files, but did not return the Aperture files.
    that's because Spotlight never looks inside packages unless you start a search inside a package directly. iphoto seems to be the only exception. I don't know how it's done.

  • Time machine will not save exclusions

    I have a Mid 2011 Mac Mini.  I installed an SSD and moved most of the data I would like to backup to an external 3 TB USB drive.  I also have a 2TB external drive I am trying to set-up for use as Time Machine.  I am only interested in backing up my photos, documents, and music.
    I set-up Time Machine to use the 2TB drive.  I have excluded everything I do not want, leaving an estimated 591 GB to back-up.  However, when I tell Time Machine to back up the data, it says I need 1.92 TB to back-up my data and I only have 1.32 TB avaiable (I guess the rest is needed to run the software).  When I re-open the exclusion list, only the default stuff is on that list.  I have followed the reset instructions at http://pondini.org/TM/A4.html and other troubleshooting there.  I have also reinstalled Mountain Lion on top of itself and that didn't help, either.
    Can anyone point me to the solution?  This is driving me crazy!  I could keep manual backups of the data I want, but Time Machine should do that for me...

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.

  • Time Machine stopped backing up now

    Time machine was working well ( i think!) but now takes up an enormous amount of space 180gb. My external drives are too small at 160gb and I feel time machine has multiplied the amount of space it needs as my hard drive only contains 75gb of data.
    Help! I have tried removing files and some applications from the back up volume, but it still wants more space than the apparent volume to back up.
    Do I need a bigger external hard drive or will it keep multiplying as I suspect it will.
    Thanks

    Rob,
    This might give you some ideas as to why it's filling up so fast.
    *_Incremental Backups Seem Too Large!_*
    Open the Time Machine Prefs on the Mac in question. How much space does it report you have "Available"? When a backup is initiated how much space does it report you need?
    Now, consider the following, it might give you some ideas:
    Time Machine performs backups at the file level. If a single bit in a large file is changed, the WHOLE file is backed up again. This is a problem for programs that save data to monolithic virtual disk files that are modified frequently. These include Parallels, VMware Fusion, Aperture vaults, or the databases that Entourage and Thunderbird create. These should be excluded from backup using the Time Machine Preference Exclusion list. You will, however, need to backup these files manually to another external disk.
    If you do a lot of movie editing, unless these files are excluded, expect Time Machine to treat revised versions of a single movie as entirely new files.
    If you frequently download software or video files that you only expect to keep for a short time, consider excluding the folder these are stored in from Time Machine backups.
    If you have recently created a new disk image or burned a DVD, Time Machine will target these files for backup unless they are deleted or excluded from backup.
    *Events-Based Backups*
    Time Machine does not compare file-for-file to see if changes have been made. If it had to rescan every file on your drive before each backup, it would not be able to perform backups as often as it does. Rather, it relies on a process called FSEvents. This is a system log that records changes that occur with all the directories on your Mac. Moving / copying / deleting / & saving files and folders creates events that are recorded in this log. At the beginning of each backup, Time Machine simply looks at this log to determine what has changed since the last backup. [http://arstechnica.com/reviews/os/mac-os-x-10-5.ars/14]
    Installing new software, upgrading existing software, or updating Mac OS X system software can create major changes in the structure of your directories. Every one of these changes is recorded by the OS as an event. Time Machine will backup every file that has an event associated with it since the installation.
    Files or folders that are simply moved or renamed are counted as NEW files or folders. If you rename any file or folder, Time Machine will back up the ENTIRE file or folder again no matter how big or small it is.
    George Schreyer describes this behavior: “If you should want to do some massive rearrangement of your disk, Time Machine will interpret the rearranged files as new files and back them up again in their new locations. Just renaming a folder will cause this to happen. This is OK if you've got lots of room on your backup disk. Eventually, Time Machine will thin those backups and the space consumed will be recovered. However, if you really want recover the space in the backup volume immediately, you can. To do this, bring a Finder window to the front and then click the Time Machine icon on the dock. This will activate the Time Machine user interface. Navigate back in time to where the old stuff exists and select it. Then pull down the "action" menu (the gear thing) and select "delete all backups" and the older stuff vanishes.” (http://www.girr.org/mac_stuff/backups.html)
    *TechTool Pro Directory Protection*
    This disk utility feature creates backup copies of your system directories. Obviously these directories are changing all the time. So, depending on how it is configured, these backup files will be changing as well which is interpreted by Time Machine as new data to backup. Excluding the folder these backups are stored in will eliminate this effect.
    *Backups WAY Too Large*
    If an initial full backup or a subsequent incremental backup is tens or hundreds of Gigs larger than expected, check to see that all unwanted external hard disks are still excluded from Time Machine backups. Time Machine will attempt to backup any hard disk attached to your Mac, including secondary internal drives, that have not been added to Time Machines Exclusion list.
    This includes the Time Machine backup drive ITSELF. Normally, Time Machine is set to exclude its’ own backup disk by default. But on rare occasions it can forget. When your backup begins, Time Machine mounts the backup on your desktop. (For Time Capsule/AirDisk users it appears as a white drive icon labeled something like “Backup of (your computer)”.) If, while it is mounted, it does not show up in the Time Machine Preferences “Do not back up” list, then Time Machine will attempt to back ITSELF up. If it is not listed while the drive is mounted, then you need to add it to the list.
    *Recovering Backup Space*
    If you have discovered that large unwanted files have been backed up, you can use the Time Machine “time travel” interface to recovered some of that space.
    Launch Time Machine from the Dock icon.
    Initially, you are presented with a window that represents “Today (Now)”. DO NOT make changes to file while you see “Today (Now)” at the bottom of the screen.
    Click on the window just behind “Today (Now)”. This represents the last successful backup and should display the date and time of this backup at the bottom of the screen.
    Now, navigate to where the unwanted file resides.
    Highlight the file and click the Actions menu (Gear icon) from the toolbar.
    Select “Delete all backups of <this file>”.
    *FileVault / Boot Camp / iDisk Syncing*
    Note: Leopard has changed the way it deals with FileVault disk images, so it is not necessary to exclude your Home folder if you have FileVault activated. Additionally, Time Machine ignores Boot Camp partitions as the manner in which they are formatted is incompatible. Finally, if you have your iDisk Synced to your desktop, it is not necessary to exclude the disk image file it creates as that has been changed to a sparsebundle as well in Leopard.
    If none of the above seem to apply to your case, then you may need to attempt to compress the disk image in question. We'll consider that if the above fails to explain your circumstance.
    Let us know if this was helpful.
    Cheers!

  • I can not get Time Machine to back up an external WD Passport 2 TB drive!  Has anyone else had this problem?  The drive is new and I was running Snow Leopard and upgraded to Lion and it still won't do it.  Time Machine backs up the internal drive fine.

    I bought 2 2TB WD Passport Drives with the intention of housing my iTunes/iPhoto libraries off my older MacBook.  I have successfully transferred the Libraries to one and am using the other one for Time Machine.  In Snow Leopard I could back up my computer to Time Machine no problem but when I did not exclude the iTunes/iPhoto drive the back up fails.  Both drives have been reformatted, permissions repaired and checked in Disk Utility and one was replaced.  I have been to the Genius Bar now 5 times.  I have tried using USB drive and FireWire.  Both drives are recognized and are working properly otherwise regardless how they are connected.  Finally yesterday the Apple store installed Lion to see if that fixed the issue and it did not.  Time Machine successfully backed up a USB Flash drive, and today I will try an older external drive.  Any ideas on what else to try??? Do I have to resort to third party software like Carbon Copy Cloned to get this done?  Any ideas why this wont work?  I am using a FireWire converter but as I said, both drives are working normally otherwise (libraries working, time machine working for the computer's hard drive.  Any ideas would be appreciated!!?

    Thanks so much but none of that helped.  It was driving me crazy because it would back up another external drive.  I just changed the name of the drive from iPhoto/iTunes Library to Media Libraries and IT WORKED!! I guess for some reason it didn't like the drive being called iPhoto or iTunes ???? I don't understand but I have tried so many solutions and exchanging things out but the name change did it????!!!
    Thank you for your help and replying to this.  Guess I made my own issue!

  • Using Time Machine to back up an external hard drive dedicated to Adobe Lightroom 5

    I recently began to use Adobe Lightroom 5 (I continue to use Aperture, as I have for years).    All of the Lightroom image files and catalogs are on one external hard drive, which I use on my iMac, my Macbook Pro, and in the digital labs of a school where I'm taking a course.
    Not yet having developed a protocoI for creating a back up of all my Lightroom image files and catalogs that I could use in the event of my Lightroom-dedicated drive's failure, I have just done a drag and drop of the whole drive's contents to another external drive (which, as it happens, I have been using for some time for my Aperture vaults).
    I am thinking of removing the dedicated Lightroom drive from the excluded list of my iMac's Time Machine (which uses yet another external drive), so that I can easily and automatically create back ups of changes to the Lightroom external drive without having to do the cumberome and inelegant drag and drop at some yet-to-be-determined frequency.  (The Macbook Pro uses a Time Capsule for its Time Machine; I envision using only the iMac's TM external drive for Lightroom backups.)
    What is the simplest and most desirable way to actually execute the backup?  I envision that it would be this: that every time I want to do a Lightroom back up, I'd mount the Lightroom external drive on the iMac (or keep it mounted if my work session has just been on the iMac) and then ask Time Machine to "Back Up Now." When the backup is finished, I'd dismount the dedicated Lightroom drive.
    A related question is what if anything would be the effect on my Lightroom work if a Time Machine back up began while I was working in Lightroom? Or if for some reason an hourly TM back up began and I needed to quickly end a Lightroom session before the backup was completed?

    Mac Basics: Time Machine backs up your Mac

  • Time Machine to back up MacBook AND External Drive?

    I have a MacBook and a 1TB G Drive which holds all of my photographs and iTunes library (none of which is on my MacBook, since I ran out of space long ago), and where I have backed up my Documents folder by simply copying and pasting.
    I bought another 1TB G Drive to use as a back up, but I have no idea what I'm doing. The first time I backed anything up I just copied and pasted again, from both the first drive and my MacBook, which is ridiculous and took hours and is pathetic.
    I want to set up Time Machine so all of my applications and settings are backed up, in addition to my files which are in two separate places right now. I'm not sure how to set up the second drive to take care of both.
    After looking at the FAQs at the top of this forum, I'm afraid that any partitions I set up may re-format the drives and thus wipe out everything I have. Any advice on how to set this up without losing my data would be appreciated. Thank you!

    That may not be large enough. It varies greatly depending on how you use your Mac, but Time Machine usually requires 2-3 times the space of the data it's backing-up. So add-up the space used on your MacBook's internal HD and the amount used on the other drive. If that's less than 500 GB, you'll probably be fine. If it's between 500 GB and about 750 GB, it might work, at least for a while.
    I want to set up Time Machine so all of my applications and settings are backed up, in addition to my files which are in two separate places right now. I'm not sure how to set up the second drive to take care of both.
    Most likely, piece of cake.

    No, Time Machine won't wipe out your data.
    First check the Format of the media drive. You can do that via +Get Info+ in the Finder. In the General area of the Info panel it will show Format. If it's any variation of +Mac OS Extended,+ then Time Machine can back it up. If not, your best bet will be to switch drives -- format the new one for your Mac, copy the data to it, then erase and reformat the old one to be used for your backups. Post back for instructions if you need to do that.
    You should erase and format the Time Machine drive with a single partition, per #5 in the FAQ.
    When you're ready to start Time Machine, click the Options button in Time Machine > Preferences. See if the media drive is listed in the exclusions box; if it is, select it and click the minus sign. Then Time Machine will back it up.

  • Will Time machine automatically back up an external hard drive connected to my iMac?

    I have a Lacie external firewire hard disc connected to my iMac, containing Aperture library. Will Time Machine automatically back up both the external disc and the iMac HD?
    Adrian

    Will Time Machine automatically back up both the external disc and the iMac HD
    Open System Preferences (gear icon on the dock) and open Time Machine
    Click on Options
    Do you see the name of your Lacie drive in the "Exclusions List"?  If yes, the Lacie drive is currently not set to backup with your Mac.
    Click on your Lacie drive to highlght it, then click the - (minus) button at the bottom of the list to remove the drive from the "Exclusions" list.
    Now, Time Machine will backup both your Mac and the Lacie drive on the next pass. Allow plenty of time for this backup, avoiding wireless if possible, and connecting the Mac directly to one of the Ethernet ports on the Time Capsule. Ethernet will go 3-5 faster than wireless, on average.

  • Does Time Machine *really* back-up everything?

    I've run into some problems with my computer and will have it repaired tomorrow. They will be replacing the hard disk, so I need to make sure I have everything before I give it to them tomorrow morning. I used Time Machine to back up things, so all should be fine. Theoretically, I guess... ;-)
    I've now restored from Time Machine back-up to a different computer - this is the one I'll be using while my own is being fixed. But: About 40GB (of about 300GB in total) seems to be missing! The file number reported by Disk Utility is about the same (I've been using the "new" Mac for a day, so I expect it to be different), and I've used "du" in terminal to find out whether there are any major discrepancies but haven't found any. Maybe a few massive swap files that are ignored? Or what could it be?
    Any idea what's going on???

    No one is an idiot.
    It is worth going to Apple's website and reading all the info on their pages about these products. They tell a lot and there are usually links to tutorials.
    Time Machine backs up everything the first time. Then it only backs up changes. When you enter time machine you will seethe series of what ever folder you are in running back into space. You can go to a specific date and the version of say a letter will be in the state it was in at the time of that back up.
    The same is true for the contest of a folder. If a back up runs at 2:00 pm and the you delete the file at 3:00 the file will remain in the 2:00 pm back up.
    There is an option to exclude files from the back up. My opinion is that backing up the system files all the time isn't worth it. I find if there is a system problem I want to reinstall the whole thing fresh.
    This works if you don't mind sitting through software installs.
    Time Machine if left alone will back up the entire system and keep it current. Once the back up drive is full however it will start deleting old back ups. It will let you know it is going to do this. You can choose to let that happen or add a new drive. It isn't the best system for a permanent archive.
    I have excluded everything but my home folder. I expect to get at least a years worth on my drive and at that point a new drive wouldn't be that big a deal.
    Hope this helps.

    How do I get Time Machine to back up my iTunes movies and tv shows?

    They're backed up automatically unless in a folder in the exclusion list of the Time Machine pane of System Preferences.

  • Am I able to use both Carbonite and Time Machine as back-ups for my iMac?

    HI,
    I have a iMac, and I have recently recently completed the initial back up for Carbonite. I also have a 2TB Seagate external hard drive that I would like to use with Time Machine. I am wondering if I am able to use both Carbonite and Time Machine simultaneously.

    Hi, and welcome to the forums.
    As bdmarsha says, yes, you can run both simultaneously.
    But one caution; there are some reports here that some of the online backup apps keep some fairly large, frequently-changing files on your system. Time Machine will back them up along with everything else, which can take some extra time and space on your TM drive.
    After your initial TM backup, see how large the incremental backups are (by watching the progress bar and info on the +Time Machine Preferences+ window). If those seem too large for the changes you've made since the previous backup, see #A2 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum), for a couple of apps that will show exactly what was backed-up.
    If you find such things, you can exclude them from TM backups, per #10 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).
