Is information stored in Time Machine considered backed up?
Sorry for the newbie questions below - I scanned the threads but didn't find exactly what I was looking for.
1) As far as backing up contents of my computer, is Time Machine (and the external drive it's running on) considered safe? That is to say - if my only back up is Time Machine to feel that my pictures, videos, etc are safely backed up - am I crazy?
2) When the external drive Time Machine is currently running on fills up, do I buy another one and disconnect and store the first one?
3) Getting close to buying a HD camcorder - so - how best to manage the big volumes needed for storage? Can I rig up a big external drive specifically for large files such as high res photos and HD video? Will iMovie and iPhoto reference such an external drive?
Thanks in advance.
Cheers.
Time Machine is currently my only form of overall backup. There are two ways to do a restore.
If you start up from your Mac OS X installation disc, you can run a utility that restores the entire volume. I have actually tried it recently, to make myself feel comfortable with how it works, and it did work as expected. I did do a clone to another volume immediately before, in case the +restore complete volume from Time Machine backup+ process failed.
The other way is to go into the Time Machine archive directly. So if I want to start with a fresh system installation instead, I can go do a system installation onto an erased volume. Then run Migration Assistant and use my Time Machine backup as the data source. Or I can migrate the data manually using Finder (the way I would really do it), by going into the Time Machine archive directly. The folder structure is organized by date/time of the backup. By using something called multi-linked files when Time Machine created the backup, Finder will show a complete backup for any available date/time, even though a file that never changed is stored in the archive only one time. In other words, each date/time folder shows everything being backed up, even though 99% of it did not change from the backup one hour earlier. So I can manually copy the files I want from the archive to the new installation, just by picking which available date/time to use.
Since I have these two options, I feel comfortable with Time Machine being my only backup for most of my personal data. For data that is extremely valuable, I back that up separately to another hard drive. But I would do that second backup (for the most critical data) no matter what backup method I was using.
When Time Machine runs out of space on the drive, it tells you. If you let it continue, Time Machine starts deleting your oldest date/time backup states to make room for the newest date/time backup states. So how far back in time you can go starts moving forward. However, there is no need to get a new drive, if that automatic process is OK and you mostly want the recent backup states. It is a good idea to buy as large a drive as reasonable, so that Time Machine has plenty of space. From my experience, Time Machine starts to take a long time to perform each run once the free space on the drive starts to become low (or gets to a point where it is deleting the oldest backup states).
You can tell Time Machine to back up attached external drives, as long as the Time Machine volume is larger than the total size of the data being backed up. To operate effectively, the Time Machine volume really should be +at least+ twice the total size of the data being backed up. In System Preferences +Time Machine+ pane, the Options button shows a list of what NOT to back up. External drives are put on the list by default. If you want an external drive to be backed up, remove it from this list.
You can generally tell applications where to store data.

I have been storing my Aperture and IMovie Libraries on an external hard drive that recently died. Fortunately I've been using Time Machine to back up to a 2nd external drive. How do I restore my libraries to a new external hard drive?
This is a tricky one.
Open up Time Machine and go back to a date using the timeline on the right side of the window when you know the drive was working and was backing up as part of Time Machine backups.
Click on the name of your Mac under the Devices heading on the left side of the window in Time Machine, and if things are working correctly you will see Macintosh HD (or whatever you have named it) and the name of the external hard drive that was backing up in the past.
Right-Click on the name of the external hard drive and then click on "Restore (name of drive) to....." You may be asked for your adminstrator password at this point.
It might be easier to restore the drive contents to your desktop if you have room on your Mac, and then copy things over to the new external drive where you want to store the Aperture and iMovie Libraries.
Once the libraries have been moved over the new external hard drive, you will likely need to "point" Aperture and iMovie to the location of the libraries on the new external hard drive. -
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.
ThanksRob,
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.

I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was? I want to make sure I will still have various important files on my new computer, like my songs in iTunes, my photos in iPhoto, etc, etc. Thanks so much in advance!
Welcome to the Apple Support Communities
When you turn on the new iMac for the first time, Setup Assistant will ask you to restore a backup, so connect the external disk and follow steps to restore all your files to your new iMac. Your new Mac will have the same settings and programs as your old computer.
In other cases, I would recommend to restore the whole backup without using Migration Assistant or Setup Assistant, but a Late 2012 iMac uses a special OS X build, so the OS X version that you're using on your old Mac won't work on the new one. For more information, see > http://pondini.org/OSX/Home.html -
Having trouble getting Time Machine to back up my external hard drive. Any suggestions?
I'm running Mountain Lion on my iMac and I've been using Time Machine to back it up to my Time Capsule. Recently, the iMac's hard drive filled up, so I moved my iTunes library to a new Airport Time Capsule. But I can't seem to get Time Machine to include the new Airport Time Capsule in its back up.
The only suggestion I can find is to make sure it's not excluded in the Time Machine options, and I can see that nothing is excluded. However, when I go into Time Machine, the Airport Time Capsule is greyed out in the Finder window.
Anyone have any ideas? Thanks in advance, I'm a little nervous about having my iTunes library hanging out there without a back up...Linc Davis wrote:
You can't back up the internal drive of the Time Capsule with Time Machine. It will only back up locally attached storage devices, not network devices. There's no way around it. You may be able to back up the TC with third-party software such as "Carbon Copy Cloner," but it will be very slow. The internal drive of the TC is only suitable for use as a backup device. It's not suited for storing original data.
yeah well you can use the external hard drive as a data extension to the time capsule internal hard drive. like a RAID in effect... -
I currently have a mini server (OSX10.8.5, server 2.2.2) that I am using Time Machine to back up 4 external drives that are connected to the server via firewire 800. I would like to use Time Machine to back up to a windows network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it for use.
Can this be done
Thanks for any and all helpThe supported targets for Time Machine backups are local (direct-connected) disks, and network targets include Time Capsule, a disk hanging off the current-generation AirPort (though not earlier AirPort devices), and OS X Server systems.
The Time Machine storage is based on the HFS+ file system, so I would not expect TM to work with SMB file services.
While there are hacks to allow Time Machine to access network drives, I would not consider those to be reliable. Skim the forum and the 'net for related details, and for previous discussions of setting this up and the related issues that can arise.
Remember to test the recovery with whatever you decide to use; whole point of backups is the ability to restore the data, after all.

I am currently in Zambia on missions work and my computer is constantly exposed to heat. I have just been trying to avoid using it during the hottest part of the day. Today though, I started it up and it was stuck on the grey page with the rotating circle for over an hour, then once the circle left, it remained frozen on the gray page. I used command + r at startup to go to the utilities page to analyze the disk. It found that there were problems with the disk, but then it could not fix those problems and told me to backup as much information as I could and reinstall or redo it all. I haven't ever used time machine to back up any of my information, but i have an external drive that I can use right now to backup my files. I can't get into my computer though to backup the files. How can I use this external drive to backup my files while the computer is currently messed up? Please help.
Emergency Backups (Data Recovery)
A) Format an external disk:
(This will erase all data on the external disk.)
Boot in recovery mode (power then Command-R).
Alternative: Network recovery boot (power then Command-Option-R keys)
To format (and erase) the destination recovery disk:
Plug in the drive you are about to erase.
Select the volume that is NOT your system disk.
Click on Partition.
Pull down under Partition Layout to 1 Partition.
Click on Options…
Select GUID Partition Table.
Name: Emergency Backup (or whatever you prefer)
Format: Select Mac OS Extended (journaled)
Click Apply.
Click Partition.
B) Try to boot in Safe Mode (power then Shift key).
(This will be a slow boot. Be patient.)
If it won’t boot in Safe Mode, jump to C.
If it boots in Safe Mode, try to boot in normal mode.
If that fixed your problem then start a Time Machine backup.
http://support.apple.com/kb/ht1427
https://discussions.apple.com/docs/DOC-4055
If not, boot in Safe Mode again.
Go > Computer.
Double click on the system disk.
Drag the Users folder to the recovery disk.
C) To clone the disk:
Boot in recovery mode.
Select Disk Utility.
Try to repair the system disk twice.
Whether or not the repair succeeds:
Drag and drop the system disk to Source:
Drag an drop Emergency Backup to Destination:
(Take care not to reverse this order.)
Click Restore (the lower Restore button).
Once your system is healthy, maintain two reasonably current backups. (Time machine restores can fail.)
Create either two Time Machine backups (good) or one or more Time Machine backup(s) and one or more bootable-clone backup(s) (better).
Use Carbon Copy Cloner or SuperDuper! to create bootable-clone recovery disks.

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,

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. -
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.

Can't get Time Machine to back up server or attached drives
Tried to use the search on these new discussion forums and was told I'm not authorized to search the server forums so sorry if this has already been asked and answered.
I'm having a serious issue trying to back up my Mac Mini Server running 10.6.7. The setup is I've got the main server hard drive running the OS and storing user folders, the second drive is storing all server data (mail, ical, etc). I have an attached Drobo that is where all our company's job files are stored. I want to back up mainly the job files to an external USB drive via time machine. I wouldn't mind having the server and data backed up as well but it's not as essential as the customer files. I have not been able to get a successful Time Machine Backup of anything. Time Machine will start backing up and hang after what seems like a random amount of data has been backed up. This can range anywhere from a few hundred Gigabytes or a few Megabytes. The last attempt has stalled out at 17MB of 518GB.
The troubleshooting I've done so far is to try to back up only certain things, so:
Format the USB Drive then try to back up only the main server hard drive, excluding all else.
Format the USB Drive then try to back up only the server data hard drive, excluding all else.
Format the USB Drive then try to back up only our jobs folder on the Drobo, excluding all else.
The result has been the same every time. Seemingly random amount of data get's copied and then the backup hangs. I do not get an error message the Time Machine backup icon on the menu bar just keeps spinning and I have the Time Machine window up that says:
Time Machine Backup
Backing up 269,376 Items
17.3 MB of 518.7 GB
This current attempt was to backup just our jobs folder and was started yesterday morning so it has been over 24 hours. Disk Checks on the external USB drive come up with no errors every time I've scanned it.
Hoping someone has a solution. One of the main reason's the company owner decided to get a mac server was how well time machine worked on his mac at home and the idea of being able to go back to pervious versions of customer jobs if necessary.I agree with Sven. I use TM to backup my server and have had EXCELLENT success. I work in a school with many teachers that love to delete files and empty the trash on their user accounts.
>>facepalm<<
They promptly come-a-runnin' crying about how they've lost that ever important document. Time machine to the rescue!
About the hanging problem... I've see it as well. I fixed it by finding the document that it was trying to back up. I copied it to a USB stick and deleted said file from the server.
I ran the time machine backup again, and it worked! I kindly asked the teacher to just remake the file in question. Luckily it wasn't anything important. I just chalked that one up to a corrupt or unreadable file.
Another thing to beware of. DO NOT expect time machine to be able to do a complete system restore on OS X server. It's great for getting those lost files while the system is up and running, but it will not work when trying to replace your Open Directory. It might get stuck on MySQL, and Mail as well. These databases are VERY finicky. If you need to back up your OD database, open up server admin and select "Open Directory."
Click the "Archive" button at the top.
To the far right hand side of the "Archive in" field, click choose.
Select the location that you want to save your archive to (the time machine drive will work) and click choose.
Click "Archive..." Type the name for your OD backup and type a password if desired. You don't need to have one.
Lastly... Smile on the inside knowing that your OD is nicely backed up and safe! -
Can you use time machine to back up an external hard drive?
I haven't used Time Machine so far and setting it up now.
Because my retina MBP has the limited hard drive size of 500GB, I'll be using a 2TB G-Tech hard drive as external hard drive.
I'll be partitioning it, 500 GB for the MBP as a time machine back-up, the rest as a hard drive for photography RAW files.
Can I set up time machine to back up the larger partition (the one with the RAW files) to a second external hard drive? Or does Time Machine only handle back-up from the main computer hard drive?
thanks!Try reviewing this information.
Time Machine FAQ
You will definitely need more than 500 GB to use Time Machine - see question 1.
Time Machine works with the main hard drive and any locally attached storage, but I don't know of any way to make it backup the second partition without resetting the Time Machine Preferences. You can do that with a cloning program.
Clone - Carbon Copy Cloner
Clone – Data Backup
Clone – Deja Vu
Clone - SuperDuper
Clone Software – 6 Applications Tested
Two backups are better than one. Drives do fail. -

Time machine slow, backing up 1,800,000 items of a few MB total?
I recently bought me second time capsule (1st one died) and use time machine to back up. It took some days to get everything on it (i'm patient, and didn't have a network cable), but now it got sort of stuck. Everytime time machine starts, it says that it is backing up e few milion items, but only displays about a 100 mb and estimates that it takes a few minutes. In reality, it never finishes, also not after 12 hours, after which I take my laptop to work and in the evening the same thing happens, every night...
Hope someone understands what is going on here!

I'm trying to set up time machine to back up on an external HD connected t my airport extreme, but the disk doesn't show as an option in the time machine selecting a disk, any suggestion anyone? My mac "sees" the airport extreme ??
The first important thing to consider here is that Apple does not support Time Machine backups to a drive at the USB port on the AirPort Extreme, so that may likely have something to do with your difficulties.
If you want to continue to try this, the drive must be formatted in Mac OS Extended (Journaled) and you almost always have to use a powered USB hub with a drive at the port of the Extreme...even if the hard drive has its own power supply....because the port on the Extreme is under powered.
Most users who try this unsupported method have corruption difficulties sooner or later, but we do hear from some users who seem to be able to make it work.
The bottom line is that there is no support from Apple on this if you have difficulties, so you may want to consider a secondary backup plan for your important data. -

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message. Clear the text field and scroll back in the log to that time. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Some personal information, such as the names of your files, may be included — anonymize before posting.
