How far back will time machine save?

i hear that it keeps growing farther and farther back. doesnt it start deleting the backups at some point? is there a way to select how much history it will save like a web browser?

Has anyone out there had a disk fill up then give a TM error. I have a 500GB external FW. It managed to go about a month then started giving me an error saying the disk was full. The only way I could stop the roor was to manually delete the earliest back-ups. I asked at an Apple store and they said that other than adding another disk that was the way to do it.
Seems to me that TM should have an option to save a certain number of back-ups then delete the older one's automatically.
Am I missing something?

How far back does Time Machine back up?

How far back does Time Machine back up? Thanks.

Thanks Kappy and Tech Guy. I'll try and digest that info--it may take awhile!
Just for info, I am using a Lacie d2 500 GB, presently it has used 263 of the 500.
It is presently backed up until January 2010 which must be the date I hooked into Time Machine. I have a 1TB iOmega which I am thinking of using for the back up drive but feel the Lacie may be the better of the two so may leave it on.
Thanks again. Cheers.

How far back in time does iCal go (accurately)?

Silly question, I know, but is there a built in limit or a point at which iCal becomes inaccurate?

Calculators with a calendar facility normally go back as far as 1904, or sometimes 1901, because of the leap year odditiy (2000 was a leap year but 1900 wasn't) so for two centuries the every four years rules works, but not before 1901.
iCal however correctly shows 1900 as not a leap year, and you can enter any earlier date you like. I haven't checked that the days of the week are correct, but I would image that it works back to September 1752, when 11 days were dropped as a result of the change from the Julian to the Gregorian calendar (which caused disturbances because people thought 11 days had been taken off their life span). Dates prior to that in iCal would not match contemporary usage.

How far back will Apple go with the new OS 10 Mavericks in it's Mac Line up?

Just wondering if my 2010 Mac Mini will be able to update to Mavericks when it comes out.

Nice !
Apple just announced 20 mins ago that the new OS Mavericks is "being released today" and it is FREE

How do I restart Time Machine back-up from scratch?

How do I restart Time Machine back-up from scratch? I have a MacBook Air that was my wife's - now given to my daughter for school. My wife never used Time Machine to back up (she simply copied files to an external drive), so before clearing her files off the Mac HD, I tried using Time Machine for the first time with an external HD. However, the Time Machine back up repeatedly failed after about 2GB of 28GB of files. I manually copied my wife's 28GB of files to another external HD and deleted all the files off the Mac HD. I then reformatted the external Time Machine drive. But when I try to use Time Machine to back up the MacBook Air as it is now with my daughter's files on the Mac HD to the external TM drive, Time Machine acts as if the 28GB of my wife's deleted files are still on the Mac HD and fails back-up after counting to about 2GB, even though there aren't even 2GB of files on the Mac HD now and nothing on the external TM drive. I don't need to save any back-ups of how the MacBook used to be - I just need to start from scratch with how the computer is now. Can anyone please tell me how to get Time Machine to think the MacBook is a brand new computer and act as if it's a first time ever back up? I tried updating to Yosemite, and tried renaming the computer in System Preferences>Sharing, plus (as noted above) deleting all the old files off the Mac HD and reformatting the external Time Machine drive - none of that worked. All I can do at the moment is manually copy my daughter's files to an external HD - very frustrating.

Hmmm.. Office is not hard to restore.
You have something major wrong (Yosemite being the primary one).
Do a verify of the source drive.. to do that you will need to boot to the recovery.. and run the disk utility from there.. it sounds like your main disk is corrupted.
Once that is complete, delete the current setup of TM and try again.. use the widget to find out why it is failing..
See Troubleshooting.
A1, A4 and A5 for further info.
http://pondini.org/TM/Troubleshooting.html
Good luck with it..
I would also download carbon copy cloner.. it is $40, but you can use it free for a time.. forget if a week or a month??.. to try out.. and make a proper backup before you start.. CCC is far more reliable than TM.. and in fact you might decide to simply forget about TM if it works and pays the $40.. because you can produce a bootable clone on the external drive which is a heck of a lot easier to use than TM.

Will Time Machine back up iTunes media on a different internal drive

I have my iTunes media on a different internal drive.
Will Time machine back up that data as well?
I have two other internal drives, each 750gb.
Does Time Machine back those drives up as well? Or does it contain itself to the OS disk?

Stephen,
Amazingly, Time Machine will do this by default!! In fact, Time Machine will back up every volume that is present at the time of the initial backup, unless told to do otherwise. I keep my iTunes and iPhoto libraries on a secondary partition of my MBP's hard drive, and Time Machine backed that up automatically.
Your backup will be contained in a "Backups.backupdb" folder on whatever external volume you choose to use for Time Machine. Within this folder, you will find other folders named for the various volumes that are being backed up. As far as I know, there is no limit to how many can be kept.

I'd like to go back to Maverick but i miss a Time machine save

Hi everyone.
Here are my 2 questions:
- First, I'd like to go back to Maverick but i miss a Time machine save. Is it possible or it would be too complicated? Complicated is another word that i'd never, ever, imagine to use with an Apple product.
- Second, how can i ask for a refund? I payed much for a high level of service and this is not even a good service
It has been a while since i wrote something in English so sorry for any errors, i'll try to fix them soon.
Thanks for the help.

I'm sure Apple will be happy to refund the purchase price for Yosemite in full...

If you look at the User Tips tab, you will find a write up on just this subject:
https://discussions.apple.com/docs/DOC-4053
The subject of buying/selling a Mac is quite complicated. Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
SELLING A MAC A
Internet Recovery, and Transferability of OS & iLife Apps
Selling an Old Mac:
• When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
• Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
Internet Recovery:
• In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
• Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
iLife Apps:
• When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
• Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
• It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
SELLING A MAC B
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
B. Clone to an external drive using using Carbon Copy Cloner.
1. Open Carbon Copy Cloner.
2. Select the Source volume from the Select a source drop down menu on the left side.
3. Select the Destination volume from the Select a destination drop down menu on the right
side.
4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
sure to opt for that.
Destination means a freshly erased external backup drive. Source means the internal
startup drive.
Step Two - Prepare the machine for the new buyer:
1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
2, Remove any Open Firmware passwords or Firmware passwords.
3. Turn the brightness full up and volume nearly so.
4. Turn off File Vault, if enabled.
5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
A. Snow Leopard and earlier versions of OS X
1. Insert the original OS X install CD/DVD that came with your computer.
2. Restart the computer while holding down the C key to boot from the CD/DVD.
3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
Optionally, click on the Security button and set the Zero Data option to one-pass.
4. Install OS X.
5. Upon completion DO NOT restart the computer.
6. Shutdown the computer.
B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
Note: You will need an active Internet connection. I suggest using Ethernet if possible because
it is three times faster than wireless.
1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
Utilities window appears.
2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
on the Erase tab in the DU main window.
4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
and set the Zero Data option to one-pass.
5. Click on the Erase button and wait until the process has completed.
6. Quit DU and return to the Mac OS X Utilities window.
7. Select Reinstall Lion/Mountain Lion and click on the Install button.
8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.

How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.
When I start a backup. Time Machine says "Oldest Backup: None; Latest Backup: None", so it seems like it should do a complete backup, but it only does a partial.

Hi I'd like to jump in here. Your app showed me this:

                    Plastic Wrapper [Local] (Last used)
                    Total size: 999.86 GB
                    Total number of backups: 64
                    Oldest backup: 2013-07-24 23:25:11 +0000
                    Last backup: 2013-11-17 01:40:47 +0000
                    Size of backup disk: Too small
                              Backup size 999.86 GB < (Disk used 453.81 GB X 3)
          Time Machine details may not be accurate.
          All volumes being backed up may not be listed.
          /sbin excluded from backup!
          /usr excluded from backup!
          /System excluded from backup!
          /bin excluded from backup!
          /private excluded from backup!
          /Library excluded from backup!
          /Applications excluded from backup!
Aside from the size of my backup drive, which I will increase at some point, I'd really like to have time machine backing up all system folders, especially Applications. How to I reset this hidden exclusions?
Thanks,
Darcy

I have an iMac and I am running out of disc space. I am considering an external drive to house my iTunes library. If I buy a second drive to operate as a back up will time machine back up the disc on the IMac and the external drive with the iTunes library

I have an iMac and I am running out of disc space. I am considering an external drive to house my iTunes library. If I buy a second drive to operate as a back up will time machine back up the disc on the IMac and the external drive with the iTunes library?

If you have a considerable photograph and/or movie collection you may want to consider off loading those to the EHD too. Here are Apple's article showing how handle iTunes & iPhoto libraries.

How do I redirect time machine to current back up?

I just sent my Powerbook to Applecare for a repair (screen, fans, and keyboard), and I just received it yesterday. The first thing I did was click time machine to go back into time to retrieve some files that I didn't want to be somehow (purposely or more likely accidentally) affected by Apple's repair. Only the problem is, there is nothing there. Can't go back in time. Then an error pops up telling me that my disk has 1.99 GB's left to use and it needs 77 to create a new back up. The issue here is the fact that my partition has 200 GB's to back up on, and the reason that I only have 1.99 is because everything is already currently backed up to the backup bundle already created and used before sending it to Applecare. How do I make Time Machine recognize the current back up again (which has been in use since October) so that I can actually access all the files and continue to back up? I know the files are there, and I know the .sparsebundle still exists (I'm looking at), so how do I make Time Machine recognize and utilize it like nothing has happened?

Thanks a lot for responding, I really appreciate you taking the time to respond. I did check the computer name and it is the same. There are no new backups since I've received my computer back from Applecare so I'm not afraid to loose and current saves, all the ones I want are in that bundle. Once I saw that it tried to create whole new back up (sparsebundle) and couldn't because it didn't have enough space, I turned time machine off to make sure nothing changes from what was previously set. It's just a matter of figuring out how to make Time Machine recognize all the backups again so that I can access the them and continue to back up on it.
I'm not sure if I wrote this in already, but thought I would to see if it helps. My external hard drive is set up with the backups on it. When I access the external hard drive in finder, it shows a file that says "Kagan Buck's Powerbook G4's backups.sparsebundle" (not exact, but you get the drift). And it's trying to create a new one of those. So my basic question how do I make Time Machine access the current bundle again to utilize it like it always used too.
Sorry again if I'm being repetitious, but I feel like that's the first time I've actually correctly described the issue.
Thanks a lot.

How can I get Time Machine to back up an external hard drive (iPhotos) that is attached to airport extreme base station. Note: Time machine is usb to macbook pro and external drive with iphotos is usb to airport extreme base station. Help please. Thanks!

Once you have the drive connected to your Mac, click System Preferences (gear icon) on the dock
Click Time Machine
Click Options
Be default, the hard drive will be Excluded from backups. Click the drive to highlight it, then click the "-" (minus) button at the bottom of the list to remove the drive from Excluded items.
The drive will be backed up on the next Time Machine pass
Everything above assumes that the hard drive has been formatted in Mac OS Extended (Journaled) as Time Machine will only backup drives in that format.

ITunes on external Hardrive- Will Time Machine back it up?

I have all my iTunes music and iPhoto pictures on an external harddrive. I have another external Harddrive that I use for Time machine. I want Time Machine to Back up the external harddrive. When I open Time Machine preferences, the list of "Do not backup" contains my external harddrive and when I try to select it and hit the "-" sign it is grayed out. What gives? How can I use time Machine to back up my music and photos? I cant keep all that info on my internal harddrive. Surely Apple must have thought of this. Help!

Had the same issue,
Had to make sure that all the drives I wanted to back up using Time Machine were in the same format. e.g. Mac OS Extended (Case-sensitive, Journaled)
When I did that it gave me the option to back up the drive(s). However, be aware that to format a drive will delete the data currently on it.
I had to move everything off the drive. Reformat. Put the data back on. Then Time Machine accepted the drive for back up.
Hope that helps?

Will time machine back up a second "internal" drive?

I have a Macbook Pro "late 2008" unibody.
I'd like to eventually buy an SSD drive to use as my "boot up / programs" drive and then use my much larger conventional drive as a "data" drive which will reside where my superdrive was. Will time machine back up this second drive or is it limited to the drive it's installed on?
If it's not possible, I'd appreciate any recommendations / tips on how I would back up the second drive or an alternate back up solution to back up both drives more efficiently.

It'll backup all except items you add in the exclude options as below:

How to Delete a Time Machine Backup - YouTube
If you want to remove an entire Time Machine backup on a backup drive, then the easiest way to do that is to erase the backup drive using Disk Utility. However, this will delete everything on the disk:
Drive Erase Snow Leopard and Earlier
1. 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 Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select the volume you wish to format from the left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
